ATTO Disk Benchmark

ATTO is another quick-take type of synthetic disk benchmark that measures transfer speeds across a specific volume length.  It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart.  We chose .5kb through 8192kb transfer sizes and a queue depth of 10 over a total max volume length of 256MB.  ATTO's workloads are sequential in nature and measure raw bandwidth, rather than IO response time, access latency etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

OCZ RevoDrive 3 X2

In ATTO testing, the RevoDrive 3 X2 drive showed some of the highest overall read and write bandwidth of the seven SSD solutions we compared here and in some cases by a wide margin.  Also, it's impressive to see just how linear and clean the RevoDrive 3 X2's performance was, starting at 16K transfer sizes, all the way up to 8MB.  In 8K or less transfer sizes, only the Fusion-io cards were able to outpace the RevoDrive 3 X2, though again, the price premium for the Fusion-io product definitely sets it apart from OCZ's consumer-like price points.
