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

The ATTO Disk Benchmark shows the new Vertex 4 drives trailing the pack in read bandwidth, by a few megabytes per second. In the write tests, however, the Vertex 4 drives perform much better and trail only the SandForce-based drives.
