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 SSD 320 Series

The Intel SSD 320 series drive smokes the previous-gen X25-M in both reads and writes according to ATTO, and bests the SandForce-based OCZ Vertex 2 in reads as well. However, the SSD 320 is no match for the SATA-III drives, including Intel's own SSD 510 Series drive.
