What to look for Brand Areca or LSI Ports 8 or more Card PCIe-3.0 8x Cache 512 MB or more Multi-lane SFF-8087/8088 Examples Areca ARC-1882 series or LSI MegaRAID 9285
Warning: You have to realize that on your motherboard adding a dedicated raid controller will entail that your video card will throttle down from PCIe-16x to PCIe-8x mode, resulting in a 10 - 15% performance penalty, due to limitations of the chipset. A dedicated raid controller, especially with around 6 disks always outperforms an on-board raid by a wide margin. To see some benchmark results, look here: Reflections
To see what meets your requirements, also consider the raid level you want to use. If raid3 or raid30, then LSI is out. You can check out what controllers are popular here: Detailed Results but you have to be registered and logged in to access the page.
The limitations are endless on this blasted motherboard! Or is that an oxymoron? Why does something designed to speed up transfer rates have to slow down the video board?
I saw the Areca 1882i at Newegg, but it said PCIe.2. So, rather than spend the money on a RAID board, would it make sense to upgrade to a new motherboard for about the same price?
The problem with 1155 based mobo's has always been the limited PCIe lanes available, something I have warned about since the beginning. They are great motherboards and you will be able to achieve good results, UNLESS you want to add another PCIe-8x card or even a PCIe-4x card, then it bites you.
Have a look at http://www.newegg.com/Product/Product.aspx?Item=N82E16816151105 which should be the gen3 model. Ask specifically for gen3, but from the description with SATA 6G ports it should be by now. The model number should mention:
91-1882DI-IX30- etc. The IX30 designation means it is PCIe-3.0 capable.
@hpmoon: What don't you understand? The question Alex asked? The 'related discussion' is not a discussion IMO, but a statement that is irrelevant to Alex question. Care to explain where I'm wrong again?
@hpmoon - you are welcome to disagree with another user but do not stray into personal insults.
Dave no need for insults. Harm has helped me many times. Although I agree with your assessment of the motherboard engineering choices in your 'discussion'
Harm, I don't see a gen 3 version on Newegg. Who carries them? My guess is that Gen 3 will cost double what this one costs. Isn't there a motherboard that can support more than 2 SATA III ports - without crippling the rest of the computer?
It is some time ago, but I was in a similar quandary as you seem to be in now. Areca gen3 cards were coming out last september, but I had to call the supplier to make sure I got the gen3 card with the IX30 code on the box, otherwise I would return it and he made sure I got the correct version. Now, six months later, I think you will find ONLY gen3 cards so maybe my worries are overdone, but nevertheless, I would ask them explicitly that if the IX30 code is not on the box, you can return it.
This is the only one I found that isn't gen 2.: http://www.arecadirect.com/arc1882i.html
Dual Core RAID-on-Chip (ROC) 800 MHz processor• PCIe 3.0 x8 lane host interface• 1GB on-board DDR3-1333 SDRAM with ECC (ARC-1882LP/1882i/1882x)• One 240-pin DIMM socket for DDR3-1333 ECC single rank registered SDRAM module using x8 or x16 chip organization, upgrade from 1GB (default) to 4GB (ARC-1882ix-12/16/24)• Write-through or write-back cache support• Support up to 8 internal 6Gb/s SAS ports
Is this the only PCIe 3 on the market? And at that price, couldn't I find a new motherboard that would support my needs?
That is the one I think would be perfect in your configuration and it has the sizable benefit of upgradable cache to 4 GB, although with only 6 disks initially, 2 GB or even the standard 1 GB would probably be OK for you, but you have the option. I do suggest you also get the BBM, battery backup module so you are safeguarded from power failures.
Another motherboard would not help you much, since you would still need a dedicated raid controller. Well, it would help you with the limitations of the PCIe lanes, but the cost is serious and I don't think (might be the wrong assumption, sorry) you want that. It would entail a 2011 socket mobo, a new CPU, possibly different memory plus the raid controller.
With your mobo, you either have to accept that adding a dedicated raid controller will set you back in video card performance (whether that is important to you depends on your workflow) or you have to choose a new mobo, CPU, etc. and whether that expense is worth it, only you can decide.
But I'm still faced with a degraded graphics board if I install this thing? Remember, I'm on a Sandy Bridge 1155 board.
Is there no motherboard in existence that can support more than two SATA 6 GBs ports?
Sorry, we're overlapping here. lol!
So, I have a choice between a new motherboard/processor and a dedicated RAID card on the current board, but not both. May not be much of a difference in cost
Most boards have 2 Intel based SATA 6G ports PLUS 2 Marvell based SATA 6G ports, but they can not be combined for a single raid array. You can consider using the remaining SATA 3G ports for an array.
Yes, that's what I have had with poor performance IMHO
I had: Two SATA 6 GBs in RAID 0 on the 6 GBs ports
Two SATA 3 GBs in RAID 0 on the 3 GBs ports
SSD system drive on 3 GBs port
Today, I moved things around. And I'm starting to do speed tests. Reinstalled Windows, reset motherboard CLRTC. Split up the RAIDs.
I have two separate SATA III drives on the 6 GBs Intel ports
SSD on the Marvel port
Two SATA II drives and DVD on the SATA II ports
I plan to replace the SATA II drives tonight.
I have two 120 GB SSDs. I wish I could RAID 0 them for a system drive, but Marvel ports won't support it according to ASUS.
Now, if I pick up the Areca, i can keep the motherboard, but take a loss on video card, which I need for workflow. I'll be editing hvd, avchd, DNxHD and HDcam EX
Are we still waiting for the PPBM for CCS6?
This is what I posted in the other thread
The only way to get more RAIDable 6Gb/s ports is to either get yourself a RAID card which in the case of your Z77 MB is not practical (it will cause your GPU x16 slot to operate at x8) or get the Asrock Z77 Extreme11 MB which has an on-board LSI SAS 2308 controller which interfaces to a PCIe 3.0 bus via a PCIe extender PLX 8747 bridge chip
Yes Alex, we are still waiting for PPBM6.
Bill and I are working on it, but due to a number of circumstances it is taking way longer than we expected. However, the basics of the new site are slowly - like molasses in winter - progressing. I will not bother you with the details, but this next test will only use Direct Export, no more AME, it will be a lot more flexible to search for data you want to see, with significant additions to the Search options and will give more graphics on individual results, once I have figured out how to create these dynamically linked charts to the fabrik lists. One of the additions yesterday was this page http://ppbm7.com/index.php/results?showall=&start=5
It is only an example, but ultimately it should show dynamically the results on the record selected on this page: http://ppbm7.com/index.php/results?showall=&start=4
The Detail View is already working, so you can see all the details of a selected system by clicking on the link on this page.
Bill, how many 6 MBs ports are on the ASrock board?
