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 I/O response time, access latency, etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

The OCZ Vector was amongst the top performers in the ATTO Disk Benchmark as well. With about 4K to 16K transfers, the Vector is able to pull ahead of all of the other drives in both reads and writes. With smaller and larger sizes, however, the Vector trails some of the SandForce-based drives, but not by much.
