Corsair Force Series 3 SSD RAID 0 Performance Results
By Mike Clements posted Jul 06th 2011
What could possibly be better than a Corsair Force Series™ 3 SSD? How about two of them in a RAID 0 stripe!
We recently published some benchmark results using a single Corsair Force Series™ 3 SSD
When used with a capable SATA 3 6Gb/s controller, the results were nothing short of awesome with just a single Force Series 120GB drive:
Force Series 3 — 120GB ATTO Result
Force Series 3 120GB — PCMark® Vantage HD Suite Score
Being the performance junkie that I am, I could not help but wonder how two of these monsters would perform in a RAID 0. So, I attached two of them to the SATA 6Gb/s headers on the ASUS Maximus IV Extreme Z, Z68 chipset based motherboard I am using for an upcoming project. This is just a small example of the performance I was able to extract from this combination:
Force Series 3 120GB x2 in RAID 0 — ATTO Result
Force Series 3 120GB x 2 in RAID 0 — PCMark Vantage HD Suite Score
RAID 0 is a great option for those desiring even more performance than a single drive can provide. Stay tuned for more Corsair Force Series SSD action to come. We're just getting warmed up here.

posted on Jul 06th 2011Have did you get that speed? I want too have that to :P I just get 400mb read and 350 write. I use X79 chipset. and my strip size is 16kb..

posted on Jul 06th 2011Hi, I have two of the 240 GB Force 3s in Raid 0 on my ASUS sabertooth z77, but I "only" get 500/500 read write. I do see the ~480 GB, so the RAID is working, but I'm not getting the expected performance. I think I used 128 KB for the stripe size. Please let us know. I'm thinking I have a driver issue. I setup the drives as RAID0 in the BIOS rather than ACHI, but I think we have to do that to use RAID...

posted on Jul 06th 2011Just an update, I was updating something in the case, and noticed that I didn't use a specified 6 GB/s sata cable for one of my 240 GB Force 3 SSD drives. I swapped the cable so both drives have the SATA cables labeled 6 GB/S, but still don't see the expected GB/S in Crystal Disk Mark. However, I was running OCCT, and watching Resource Manager, I thought I did see > 1GB/S. Anyway, it's fast and maybe in actual use I'm getting the perf, but I thought I would be able to duplicate the results in a synthetic benchmark... Any thoughts or advice appreciated.

posted on Jul 06th 2011OK, I guess after more research, I guess my RAID0 is performing as it should, since with non-compressible data a single Force 3 "only" sees about 250 MB/S per this article: http://www.xbitlabs.com/articles/storage/display/corsair-force-gt_3.html#sect0 I'm assuming the speeds here are for compressible data, which aligns with the results above.
