Crucial m4 128GB vs OCZ Vertex 3 MaxIOPs 120GB

[Marc HFR]

The Corsair Force Series 3 specs state Random Write 4K 85,000 IOPS (Aligned)

Where did you read that it's random and that it's write ?

We only go that on Corsair website :

Sequential Read/Write (using ATTO Disk Benchmark)
550 MB/s sequential read
520 MB/s sequential write
85K IOPs (4K aligned)

And in the press release

"The Force Series 3 features the highest performance version of the latest-generation SandForce SF-2281 SSD Processor with out-of-box read and write speeds of up to 550 MB/s and 520 MB/s respectively, and an impressive 85000K IOPS for measurably faster system response, boot times and application load times than SATA 2 solid-state drives"

Edit : Finaly got it from Corsair by mail
"The 85K IOPs number is 4K, 100% random, 100% write, 4K sector-alignment, using IOmeter 2008. This was done using an Intel P67 system, using the latest Intel RST drivers."
