ATTO Disk Benchmark
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
OCZ Vertex 3 (SATA II / 3G)
OCZ Vertex 3 (SATA III / 6G)
Talk about impressive. In the ATTO Disk benchmark, the OCZ Vertex 3 offered up the best all around scores, matching the enterprise-class Vertex 3 Pro. There was some anomalous behavior when the Vertex 3 was connected to SATA II port, but we hope anyone contemplating the purchase of this drive connects it to a SATA III port to let the drive really spread its wings.
