ATTO is another "quick and dirty" type of 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 6 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.

Intel X25-M G2
OCZ Vertex 2
Corsair Performance 3 Series
OCZ Vertex 3 Pro
Here we have yet another impressive performance by the upcoming OCZ Vertex 3 Pro. Be careful when looking at the graphs, however, as the Vertex 3 Pro offers so much more bandwidth than the other drives, the X-axis on the chart uses a different scale. In the ATTO benchmark, the Vertex 3 Pro puts up 555MB/s reads and 525+MB/s writes. The write performance of the Vertex 3 Pro is nothing short of phenomenal here.
