Sequential Read/Write Speed

Using the 6-22-2008 build of Iometer I ran a 3 minute long 2MB sequential test over the entire span of the drive. The results reported are in average MB/s over the entire test length.

As expected, the sequential speed of the Agility 2 is no different than the Vertex LE and Corsair Force drives. It looks very good.

2MB Sequential Read - MB/s

2MB Sequential Write - MB/s

Controversy, Corsair Responds Random Read/Write Speed

    Thanks for another great article. I'm patiently waiting for a (decent) 512 GB SSD in my budget so I can just throw everything besides media files on it; 256 GB might work, if I wasn't so damn lazy. Plus, I'd rather have a half full 512 GB drive than a 90+% full 256 GB drive. Reply

    90%+ full 256gb, I hear ya. I've been digging over as many SSD reviews as I can in the last couple days. I WANT to replace my 256gb 5400rpm in my notebook, but just can't quite squeeze everything into 200gb. Reply

    I am waiting until the price is at least down to $1 per gigabyte for a decent ssd. I figure I can get by with about 128gb of space. Reply

    my problem is the ~120gb of development VMs, I can't get rid of them, but since I'm in vmware all day a SSD would be heaven sent for general performance. I'm keeping things pretty slim at ~190gb out of 256gb, but that 200gb mark is just too tight. I'd buy a 300gb agility 2 today if it existed. Reply

    I thought the OWC controllers were discovered to have the SF 1200 controllers?

    Also, can we get a review on the 50g Vertex LE that are selling at New Egg, Thanks

    Those numbers are from the older OWC Mercury which used a limited run of SF-1500. The newer drives going forward are SF-1200 based. I'll be phasing them out of our graphs as a result.

    Take care,

    When are we going to see benchmarks on the new intel driver that's faster than microsoft's driver and it supports trim with raid and we shouldn't go off of just prices MSRP but actual newegg prices and maybe even have a low to high # for example Intel X25-M Mainstream SSDSA2MH160G2R5 ($400 - $489). Also include the 80gb version specially since its around $215 - $225 Reply

    I agree on the prices... Street prices of OCZ's Indillix drives are much lower than that Corsair Nova for instance, since OCZ ALWAYS has $20-30 rebates going on their drives (and they're just cheaper to begin with)... OCZ's Nova equivalent, the Solid 2, is like $300 flat after MIR.

    Intel's newer SATA drivers don't enable TRIM in RAID, just w/RAID... You can have a SSD w/TRIM support and two HDD in RAID on the same controller with said drivers (something you couldn't do before), but you still can't RAID two SSD and retain TRIM support. AFAIK they didn't dramatically alter performance either but if you've got a link to tests that say otherwise I'd love to see it... I haven't bothered to install them yet.

    but you do have to admit it is strange that imsm 8.9 was used for the testbed instead of irst 9.6. 8.9 doesn't support trim at all! one has to wonder how this might affect (or not) the benchmark scores. Reply

    "The SandForce SF-1200 controller used in the A-DATA S599 with Intel’s latest RST 9.6 drivers is the fastest 2.5 inch solid state drive for Windows users at this time. This combination is able to outperform every other drive we have tested to date in all around performance." Source tweaktown but they compared it to another 1200 drive instead of using the same ssd with both drivers. This is what intel says "Is there TRIM support for RAID configurations?

    Intel® Rapid Storage Technology 9.6 supports TRIM in AHCI mode and in RAID mode for drives that are not part of a RAID volume.

    A defect was filed to correct the information in the Help file that states that TRIM is supported on RAID volumes."
