1. Re: Question regarding Areca 1880 - "ARC-1880ix -12"
Harm Millaard Jun 9, 2011 11:55 AM (in response to mikeklar)You have to make sure that the PCIe slot is not overclocked by more than 3 - 5%.
FW means the firmware. That is normal during the booting.

Bill Gehrke Jun 9, 2011 1:30 PM (in response to mikeklar)That HD Pro "File Benchmark" does not mean much to large contiguous video files, it is one short burst and probably is more of measuring the speed to and from the cache. The tests that are more meaningful are "Benchmark" the total full surface read and write files. Here are my three files below.. As you can see there is no 1,000 MB limit on the full Benchmark. One thing that you could do is see if you have one slow drive that I have experienced on my former 8 x 1 TB drive array. It of course is taking one drive at a time out and testing until you find the culprit.
I am not overclocking the PCIe bus but I am running stably at 4.2 GHz on my i7-980X. My Areca boot up does say "Waiting for "F/W" to become ready" but does not say anything about the 300 second timeout, I guess that is later firmware.

mikeklar Jun 9, 2011 2:11 PM (in response to Bill Gehrke)Thank you both
Glad to hear F/W stands for firm ware
I do believe one of my drives is slower than the rest. With the previous Adaptec RAID card the software did indicate one drive, including its location, which would not negotiate top speed about one in ten times the system was booted up. To that end I ordered another HD and will replace the slower drive. The good note on that is knowing which drive it is
Also, the PCI frequency will be lowered, right now it is at 111, as well the IOH PCIE Voltage is at 1.51050.
Thank you again.Cheers,
Michael

Just to let you know, resetting the PCIe slot to its normal setting did the trick and allowed over-clocking as before with no issues on booting the RAID card.

After resetting the PCIe bus to its normal state the card boots up with the I7 950 running at 3910 MHz
Regarding the HD Pro "Benchmark" - after changing the supect drive the readings remain the same. Also, performed a complete volume check and the results are "0 Errors". It appears the old ADAPTEC RAID card may have been the problem, not the drive. As well I'm using the old cables, having been unable to procure 6Gb/s cables (as yet) and am wondering if this could be the reason for the lower read speed when compared to yours.
Cheers,
Michael

Bill Gehrke Jun 16, 2011 11:16 AM (in response to mikeklar)I doubt that is the cables, I am fairly sure that my cables are of the 3 Gb/s variety

Rishaar Aug 15, 2011 6:23 PM (in response to Bill Gehrke)Hi Bill & Mikeklar (and Jim & Harm if you are here)
I'm currently setting up my Areca 1880ix-16 with 8x 1TB Hitachi 7k1000.c, probably going for a Raid3+Hot spare.
It may be a stupid question but i can't find an answer on this forum:
During the setup, in the "Greater than 2TB volume support" submenu , i have 3 choices: "No"(obviously not), "Use 64bit LBA", "Use 4K Block" and i'm wondering wich option works best with PP CS5.5.
Any suggestion will be most welcome

Not a stupid question...
LBA (logical block addressing) is just a consecutive number of sectors on a drive ( i.e. 0, 1, 2, 3, ...) each sector is genrally 512 Bytes.
32 bits will allow for access to 2 TB of data ... Anything configuration over that, i.e. 48 or 64 larger than 2TB you need to have more than 32 bits with LBA indexing.
Hence, I would use LBA and "4K Block"
Surely, some of the more knowledgable people here will either confirm this or make other recommendations.
Cheers,
Michael

Harm Millaard Aug 15, 2011 9:28 PM (in response to Rishaar)In the Areca setup, use 64 bit LBA. In addition, check in disk manager that Windows sees the volume as GPT.
Look here for details: Adobe Forums: How to access more than 2 TB of disk...

Rishaar Aug 15, 2011 10:25 PM (in response to Harm Millaard)Thank you Mikeklar and Harm for the useful information !
by the way, I have those 3 good WD Caviar Black i wanted to recycle in Raid 0 through the MB (p6x58D premium) but it seems to have trouble running Raid (0 & 1), it will just show me a blue Hardware failure screen after POST and reboot, no matter how i try...(the disks are fine)
Since i have 8 ports unused on the Areca, I was thinking to set those 3 HDDs in Raid 0 on it , in addition to the 8 HDDs Raid 3 +spare array.
I'm pretty sure the Areca 1880-ix-16 4GB can handle the load but what do you think ?
(My goal is more about using those 3 HDDs cleverly than achieve "ultimate performance")

I'm still playing around with it, but i am really starting to understand the value of such a good card
