    System Recommendations

    JayNewWeb Community Member

      Hi Harm,

       

      I've read this thread and have a few questions for a system I'm looking to build, please.

       

      [Naturally, while I'm directing that towards Harm, I hugely appreciate advice from anyone else, too.]

       

      I will mainly be running Premiere CS5 and the common related apps. My budget for everything excluding software is about $5,000 ($4,000 is okay too).

       

      CASE: For a case, I'm not into contours, windows or lights. I like the clean, "business-like" look of the Lian Li PC-A77F you recommended, for instance -- though that's currently unavailable on NewEgg as I type this and I'm wondering if there's a reason -- such as it being discontinued for another model or something (or else I can just look elsewhere). It seems to provide plenty of cooling, and options for quieter fans. So, can we confirm this as the choice, please, or suggest a similar alternative? (Note that once I decide on the case, I may ask your advice on upgrading the cooling, including specifically for the GPU, which I notice the Lian Li PC-A77F supports.)

       

      MOBO: ASUS P6X58D. I'm guessing that's a good choice that should require no further dialog.

       

      CPU: i7, but then the question is 920, 930, 980x? I'm not an enthusiast and would normally never consider overclocking, but I see you recommend it. I will need you or someone to point me to how, but you say it's simple so that's fine. Just as long as I never risk it crashing and corrupting my OS. (Note that I read somewhere that overclocking requires slowing down the memory and it becomes almost a wash, but I don't know the details or how reliable that was.) As to cost, well, it becomes a question of where it hits the point of diminishing returns. If there really is a significant time difference when encoding, I'll pay for it. The time it saves me will be worth it. I'm not going to begin to try to guess how to quantify this, or figure this one out without your advice.

       

      GPU: That will be the GTX-470, thank-you-very-much.

       

      RAM: What I'm currently looking at is "Kingston HyperX 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) XMP Desktop Memory Model KHX1600C9D3K3/12GX Intel XMP Ready." I'll go with whatever you suggest, and will appreciate your advice on generally ballparking the performance difference between 12 GB vs 24 GB.

       

      HARD DISK DRIVES: At your suggestion, I did a lot of reading and chose the Samsung SpinPoint F3 for my choice for hard drive. I will go with a total of five hard drives: one for OS/apps, one for swap, and three in a RAID-5 array for data.

       

      RAID CONTROLLER: I have gotten unanimous advice not to use the on-board RAID, but don't yet have any suggestions for the controller card to get. I have had used LSI before and am told it's one of the best. I'd appreciate your advice.

       

      PSU: I know I need "plenty." Would you care to make a recommendation? (If using the Lian Li PC-A77F, I believe mounting the PSU in the bottom is preferred. Would you agree?)

       

      COOLING: Once the choice for case and mobo is made, I'd appreciate your advice on an aftermarket CPU fan if any and extra GPU cooling if any. I don't know that you'd suggest getting into water cooling for this system, and I assume I can handle quieter aftermarket case fans on my own.

       

      BURNER: I'm planning on burning DVDs and CDs, and have not even begun to explore Blue-ray at all yet. I'm strictly producing business presentations. Do you suggest I get a BR burner, or just a standard DVD/CD burner? And would you care to suggest one?

       

      Thanks so much!

       

      Jay

          Jay,

           

          The PC-A77F case is a new model this year, so it should be available. Might be temporarily out-of-stock. The alternative is the previous model the A77B, but I have not yet found any significant differences between the two.

           

          CPU: the 920 is no longer produced, the 930 has taken it's place, so actually you have to choose between the 930 or the 980X, at quadruple the price. Undoubtedly, the i7-980X is the faster CPU. Whether that is worth the investment is up to you.

           

          Memory: Your choices are limited to http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007611%20600006078%20600006 127&IsNodeId=1&name=DDR3%201600%20%28PC3%2012800%29 with this one looking the best: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231381

           

          Raid controller: This is my favorite http://www.newegg.com/Product/Product.aspx?Item=N82E16816151049&cm_re=areca_arc-1680ix-_-1 6-151-049-_-Product

           

          PSU: 1000W modular CoolerMaster or Corsair. Like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171056

           

          CPU cooler depends on your memory choice. Let's review that when you know what to go for.

           

          BR, let it be for the time being. you have plenty of space in the case to add 1 or 2 later.

           

          Hard disk: If you opt for a hardware controller, like the Areca, I suggest you add a couple of F3's right now. A 3 disk raid5 is not very fast and if you add a couple to them, it will make the raid a lot faster, and 2 extra disks won't bring you over budget.

           

          I haven't calculated where you come out, but if the choice is between the 980 and the Areca controller, I would opt for the 930 + Areca, instead of the 980 without the controller.

           

          It may be better to create a new topic for this. [Done]

            Hi Harm and Jay,

             

            Jay, you are building a system very similar to mine (no wonder, we both follow Harm's recommendations !). As for the case: I called Xoxide's (distributor) customer support (561-282-6001), and I was told that the Lian Li PC-A77 will be available in mid July. (I will call them again tomorrow.)

             

            About the raid: Harm, I am a bit confused. You suggested to me to use the ICHR10 chip on the P6X58D board for raid (with 4 Samsung F3 HDs - the fifth is for the system and programs). You are saying here that 3 drives (for Jay) in RAID 5 is not too fast, and suggest the Areca controller (with additional drives). Shouldn't I do the same then? (BTW, there are only 5 bays for SATA hard drives in this case - how do I add more drives if I want to?) I might have misunderstood something, please help me.

             

            Also, I have already ordered (and received) the Corsair Core i7 XMS3 12 GB PC1280 DDR3 memory (for $330). Is this inferior to the one you are suggesting to Ray ($500)?

             

            Thanks (again),

             

            Laci.

              Hi Laci,

               

              That case (note the full designation of PC-A77F) looks like it's ready to order today on NewEgg: http://www.newegg.com/Product/Product.aspx?Item=N82E16811112261&Tpk=lian%20li%20pc-a77f. It just now let me put it into my shopping cart and was asking how I want it shipped. I stopped there since it was only a test for you but it seems it would have told me by then if it was not available to ship right away.

               

              I'm not sure but I'm guessing that case will easily handle all the drives you and I want.

               

              The specs say:

               

               

                 External 5.25" Drive Bays:   12

                 Internal 3.5" Drive Bays:      9 (Use 5.25 x 6 Bays)

               

               

              I'm really not clear on what that all means, but I think that means we can put 3.5" drives in 5.25" bays -- perhaps with a mounting bracket/adapter that we'll need to hunt down (?).

               

              I also think we "may" want to stay with no more than a total of six drives including the optical drive in order to "hopefully" still have room for one intake fan in the lower portion of the front face of the case -- unless the advice we get is that the other fans and optional GPU cooling support will more than suffice, and/or that water cooling is advisable and realistic. Cooling is a big priority, especially when adding those new Fermie-CUDA GPUs, which I learned the hard way.

               

              As to memory, FWIW my main video guru is now also telling me it's a subjective judgment call as to whether to go for the more expensive RAM.

               

              Good luck with it!

                Well, this is just plain cool!

                 

                How about a mounting bracket/adapter for putting 3.5" drives into 5.25" bays that has a built-in fan for the front panel of the case?

                 

                Check this out:

                I am sure I'm going to be very happy with this case. Worth every penny from what I can tell.

                  To avoid confusion about both the case and about disks and raid, let me explain.

                   

                  The case has space for three 3.5" disks at the back in the top and it has 12 5.25" bays, of which 6 are pre-configured to take 3.5" disks. If you need more space for 3.5" disks, you can use this: Super Micro Computer, Inc. - Products | Accessories | Mobile Rack | CSE-M35T-1

                   

                  With three of these, you can have 15 disks in front, 3 in the back and still have room for 2 burners and 4 2.5" SSD's. So you have some room to grow. The alternative is a couple of these: http://www.lian-li.com.tw/v2/en/product/product06.php?pr_index=279&cl_index=2&sc_index=5&s s_index=12

                   

                  As a very rough indication of Raid3/5 performance, you can use this approximation:

                   

                  Performance wise it will achieve around 85%  (X-1) on reads and 60% (X-1) on writes over a single disk with X being  the number of disks in the array. So with a 6 disk array in RAID3/5, you  get around 0.85x (6-1) = 425% the performance of a single disk on reads  and 300% on writes.

                   

                  So with X being 3, as in Jay's initial suggestion, he will get around 170% on reads and 120% on writes compared to a single disk. With 4 or 5 disks those numbers would be around 255% R / 180 % W and 340% R / 240% W.

                   

                  But using the ICHR10 carries a penalty in terms of CPU load, which especially with AVCHD material, you want to avoid. That is where a dedicated hardware controller comes in (at a price). However, with the limited number of SATA ports on the motherboard, some of which are used by the burners, the OS disk and the eSATA port, you may no longer have a choice.

                    Laci,

                     

                    You have chosen good memory, but you use 2 GB sticks, for up to 12 G total. Jay starts with 4 GB sticks, initially a set of three will also give him 12 G but he has the possibility to add another set to increase memory to 24 G total.

                      Hi,

                       

                      for psu I would recommend a 1000w Coolermaster or Corsair, Also consider the Corsair 3x4gb Memory (I have this in my PC).

                       

                      as Harm recommended supermicro 5 bay enclosure, also have a look at this: (I have in my PC)

                       

                      http://www.newegg.com/Product/Product.aspx?Item=N82E16816212014

                       

                      also have a look at the Lian Li Pc-p80b,

                       

                      good luck

                        Hi Harm,

                         

                        Your help is hugely appreciated.

                         

                        Can I please ask three questions to expand on your description about RAID?

                         

                        1. You had suggested to me earlier that I might want to add two drives to my intended three. I'm curious if you have an opinion about going up to six or where the point of diminishing returns might be. The question of where the bottleneck in working with CS5 might be is obviously a key consideration.

                         

                        2. I've just read up on RAID 5 vs RAID 3. It seems that for writing video to disc (encoding) RAID 3 can be faster, while RAID 5 can be faster for numerous smaller writes and will be better for rebuilding the array in the case of a disc failure, which is a plus for me personally but so is speed. I think RAID 5 looks preferable overall but, again, a big question is the extent to which you think the hard drives will be the bottleneck with the kind of general video editing and encoding that a user like me might be doing... which still comes back to RAID 3 vs RAID 5 as well as a reasonable number of drives.

                         

                        3. My video guru suggested I might save money with a lower priced disk controller card than the one you had suggested to me. He suggested I might go down to a 3ware 9750-8i controller: http://www.newegg.com/Product/Product.aspx?item=N82E16816116108. You had suggested an Areca ARC-1680IX-12-4G: http://www.newegg.com/Product/Product.aspx?Item=N82E16816151049&cm_re=areca_arc-1680ix-_-1 6-151-049-_-Product. Can you perhaps please comment on whether you think I lose anything meaningful with the lesser-priced 3ware? (Note that I don't anticipate ever going to eight drives in the RAID array, which is apparently the limit with the 3ware card.)

                         

                        Thanks again!

                          Out of curiosity, are there any advantages to the aftermarket drive bay enclosures over the one(s) offered by Lian Li (other than cost I presume)? It seems one advantage might be fitting five where their might only fit four. Other than that, might theirs be optimal for fit and/or cooling? Am I missing anything?

                           

                          Thanks!

                            Hi,

                             

                            I only recommend the 5 bay enclosure if using Raid Cards. If you have a failed HD a light will flash, and you can then replace the HD easily and quickly.The chenbro enlosure I have keep the HD cool at aprox 25c max. For power there is also only 2x molex required. its a good invesment, that will save you time and effort if you do have a hd fail.

                             

                             

                             

                             

                             

                            Regards

                              I assume that's an advantage of "hot-swap" capability, then, am I right?

                               

                              Of course, shouldn't any good RAID controller have numbers on the drive cables, and when one of the drives goes bad shouldn't the interface show you which one it is based on the cable numbering? Meaning that while the hot-swap is obviously more convenient it shouldn't be earth-shattering to replace an occasional bad drive anyway?

                               

                              Am I on the right track?

                               

                              Thanks again.

                                Jay,

                                 

                                1. The point of diminishing returns will depend heavily on your typical projects and your editing style. As Baz and I have both experienced, there is not much difference between 10, 12 or 14 disks in a raid30 array, because we run into the limitations of the PCIe bus.

                                 

                                2. Raid5 is better for reading and raid 3 for sequential writing. IOPS is better with raid5, sequential work is better with raid3. Rebuilding with raid5 carries a heavy penalty and is much better with raid3.

                                 

                                3. There used to be a time where 3Ware with their custom I/O processor were about the worst performer in raid land. Maybe things have changed. A 4 port card means you never can use more than 4 disks. I find that very restricting. Once upon a time I started out with a 2 port card, then moved to a 12 port card and if I were to get a new card now I would only consider a 16/24 port card, with the nod to the 24 port version. Also consider that Areca is the only card to support raid3 and that the cache can be upgraded from the standard 512 MB to 4 GB only on the 12 + port versions.

                                  It depends on the Raid card you go for.

                                  I also use the 5 bay enclosure for non raid, using the hot swap for saving client files, or for backups ect.

                                    Harm, Jay,

                                     

                                    Thanks for the advice. Now I understand (at least I think, I do) the issues with the raid. (And I mistook the number of SATA drive limitation by the case with the limitation by the board .) I am not going to go for an external RAID enclosure this time, instead I will use the 5 HD solution (one for system, 4 for storage in a RAID 5 configuration) suggested originally by Harm.

                                     

                                    Thanks again,

                                     

                                    - Laci.

                                     

                                    Addendum:

                                     

                                    Harm, My already purchased P6X58D MOBO has 6 SATA 3.0 and 2 SATA 6.0 ports. This is exactly enough for 2 burners, 1 eSATA port and 5 internal SATA HD (which I also have by now) - as you suggested earlier. This setup would work fine with the board (with the ICH10R chip).

                                     

                                    In one of our earlier discussions, I was asking what (software/hardware) to use for RAID: Laci: "...I do not need any extra hardware for RAID 5 - the OS will do it for me..." Harm: "...No, use the on-board ICHR10 chip for that..."

                                     

                                    At that point, I assumed that this chip would 'do everything related to RAID' (and not the OS or the CPU). However, in one of your recent postings, you wrote: "...But using the ICHR10 carries a penalty in terms of CPU load, which especially with AVCHD material, you want to avoid. That is where a dedicated hardware controller comes in (at a price). However, with the limited number of SATA ports on the motherboard, some of which are used by the burners, the OS disk and the eSATA port, you may no longer have a choice..."  Does that mean that

                                        

                                         1. even with the ICH10R chip, we would still lose CPU power?

                                         2. How severe is this load on the CPU?

                                     

                                    And this is just a question to educate myself (I do not want to buy a RAID card at this point):

                                         3. Why are you saying that  "...you may no longer have a choice..."? Wouldn't a RAID card support more than my 4 HDs? Could they be internal HDs?

                                     

                                    Thank you again,

                                            Hi Jay, I was about to place an order for the A77F case on NewEgg (that you kindly researched for me) when I noticed all those blue lights on their picture. Do you know if those lights can be disabled? One of my original requirements was a non-gamer case (no lights, no dancing, etc.) Of course, I can always ask the Xoxide one of the main distributors of that case.) Thanks, and thanks again for the previous message, Laci.

                                              Hi Laci,

                                               

                                              I'm with you on not wanting the lights.

                                               

                                              I'm not in a position to offer last-word authoritative info for you, but from my reading of many reviews it seems to me to be pretty certain that it's very easy to change the fans out for standard fans that are identical exept that they don't have lights. I don't know if CM makes them or sells them per se, but I'm quite sure it's a standard fan that's very easy to replace without lights.

                                               

                                              Also, at least one end-uder reviewer mentioned how happy he was with the fact that the fans that come with the case actually have an "on/off" switch for the lights. Another end-user reviewer said how happy he was after replacing the blue-light fans with green-light fans. So, lights are not a big issue.

                                               

                                              After all the reading I've done, I'd make sure to talk with the distributor anyway. Even things like aftermarket CPU heatsinks or cooling fans may require spefically confirming what will fit with what. If you're not adding anything like that, though, and it's just fans without lights, it seems that will be a pretty simple matter. Still, even for the fans, I'd certainly check with the distributor.

                                               

                                              Or, search to see if that reviewer was right that there's an on-off switch for the lights.

                                               

                                              Have fun!

                                                  Simple solution:

                                                   

                                                  Cut one wire to the LED on the fan, but not to the fan.

                                                   

                                                  Second problem: ICHR10 raid.

                                                   

                                                  I recently encountered someone who had the most atrocious results on his raid5 with the ICHR10, reading OK, but writing was really in the same league as USB disks. We haven't figured out a solution yet, but numerous reports exist about this behavior on Intel and Asus mobo's. Can you imagine a 2,000 x 4 R0 writing at 25 MB/s?

                                                    WOW something is seriously wrong there.

                                                     

                                                    we do a lot of raid 0 onboard (discourage raid 5/6 with onboard)

                                                    this is also where if you dont have the Enterprise drives you will run into major issues!

                                                    (drives dropping out)

                                                     

                                                    whoever has that issue should break down the raid and test each drive individually sounds like a bad drive

                                                    (lots of bad sectors)

                                                      Hi Laci,

                                                       

                                                      Glad to hear the plain fans are available and not expensive -- and the distributor can confirm compatibility.

                                                       

                                                      As to RAID, I've spoken to a few rather experienced techs who all say RAID 3 is all but obsolete. (I don't presume to be in a position to debate Harm on this, of course. I'm just feeling my way, like you.) One says RAID 3 is not nearly as safe in terms of recovery in the case of hard disk failure as RAID 5 (he's says that with all parity info on one drive with RAID 3, if that drive goes you're toast).

                                                       

                                                      They all say RAID 5 with three or more drives is the best balance between performance and safety.

                                                       

                                                      I don't know much about RAID 0 but from what I can tell that's also pretty common. As is, of course, RAID 1 mirror. I don't know about RAID 6.

                                                       

                                                      All techs I've spoken with are saying on-board RAID is rarely the most advisable route. I don't know about CPU load but for numerous reasons a controller card is apparently better, the main reason being you'll probably get better and more reliable performance.

                                                       

                                                      Also, it seems that that 3ware controller I mentioned in post # 8 in this thread is probably a rather good choice for the money (and it supports 8 drives).

                                                       

                                                      Good luck!

                                                        Back from vacation but saw this Harm. Remember that the write policy set in the controller software for the raid array that causes this issue with Win 7. This has to do with Win 7's cache policy for storage. If you don't set your array to Write back policy then Win 7 slows the write speed down as much as 90% to ensure data integrity writing to the drive should the power fail. It really is silly but that is what Microsoft decided to do with Win 7. Most controllers management software allows you to set the Write policy to Always Write Back. The onboard ICH 10 with the Intel Rapid Storage Manager requires you to select the Advanced option when creating a raid volume and then selecting the "Enable Write Back Cache". That is the same as "always write back" on standard enterprise controllers. That  will force Win 7 to change the cache policy for storage to performance and then your write speed should be around your  read speed. Hope that helps.

                                                            The CPU usage with the onboard raid is 8 to 12% when under load from the controller. Average is 5 to 8%. I do not recommend using the onboard for raid 5 at all. It's perfectly fine for raid 0 and 1 but not nearly good enough for raid 5. It takes FOREVER(I am not joking here) to initialize and or rebuild a raid 5 with the onboard controller. Where as an Enterprise level raid controller can initialize or rebuild an array in 1 to 3 hours depending on how big the array is. The parity integrity is far better on a enterpise level raid controller as well which is the entire point of even using a raid 5. If your redundancy has a greater chance of corrupting with the onboard then you are gaining far less with raid 5 than what you should by going with the onboard controller. 1 last reason is the drive time out issue. This has become extremely common now days with the current drive industry and bad blocks on discs coming off the production line. If you couple this with non-enterprise drives then a drive can be marked out as bad as it gets caught in a loop trying to address data to a bad block area. The raid controller thinks the drive quit communicating whiles it's caught in that loop and marks the drive as bad. Now your array is degraded and you have to rebuild. Once again this takes forever on the onboard raid. Consider this carefully before you proceed.

                                                              ECBowen, I have 5 Samsung F3 (HD103SJ) 1 TB drives (one for the OS+programs and 4 for RAID 5 - following some earlier pieces of advice in this thread). This system is for HD editing of hobby/family videos. Reading the latest comments, it seems to me that even for my 'limited' use, I should go ahead with an onboard RAID controller. Any suggestion for a decent (enterprise level?) one (but which is not more expensive than the whole computer )? Thanks for all the good data/advice, Laci. (P.S. Using a RAID card, do I still have to select the "Enable Write Back Cache", as you mentioned it in one of your earlier messages - so this is a general Win 7 issue, or this is relevant only for the ICH10R RAID solution?) (P.P.S. I am looking at the 3WARE boards - that's what Jay suggested earlier...)

                                                                                The Intel Matrix Storage Manager that came embedded with the system was an older version, from Feb 2010 (8.0.0.1038).  While both the Intel and Asus websites have newer versions posted (8.9.0.1023) they aren't the newest one available in the link below, especially if you use their tools to scan your system for recommended updates.  Only when installing the newest one was I given an option to install the Intel Control Center with the Intel Rapid Storage Technology app (insert trademark sign here). These are Windows apps which give you access to the "Advanced" button referred to above, which lets you enable write-back cache.  The prior version was only accessible via POST (CTRL-I) and did not have any advanced options.

                                                                                 

                                                                                We did test the individual disks before doing this and all checked out identically, so either they are all fine or all identically screwed up.

                                                                                 

                                                                                Hope this helps others having similar problems.  For the record, here's a link to the newest version:

                                                                                      May I chime in here about the RAID setup question.

                                                                                      I'm going to built a "hackintosh" to be able to use all the different softwares but also to be able to customize it for my needs.

                                                                                      I'm mainly going to work with CS5, because of my projects using RED cameras, but I also need to be compatible with Final Cut and am planning to go the DAVINCI RESOLVE route.

                                                                                      I'm new to the RAID setup question and read through a lot of posts, but am still a little bit confused. Maybe someone can give a recomendation how I should set it up for my needs.

                                                                                      My system is planned to have two internal SSD drives for both OS (Mac and windows) and applications. Also I'm planning on a 4 RAID hotswap disc array. The Computer will also have an internal CF card reader, esata, fire wire 800, Bluray burner and the Possibility to turn the Fans of with temperature Control for use on set while takes. All set up in a 19' case. I will also purchase an LTO4 drive for long time storage.

                                                                                      So I want to use may sytem

                                                                                      1. for DIT usage on set. Offloading Data of CF cards and drives to two RAIDS while shooting and maybe an external or to LTO4 in the evening.

                                                                                      2. For editing, color corrections, special Effects, and Compositing.

                                                                                      So how should I set up my disc array for best Performance and security working in HD, 2K and with R3D's?

                                                                                      Is there one setup that would work for both purpusses or would I need to change it fo each one?

                                                                                      Should I install another internal drive for documents and a bit of personal stuff?
