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 Micron RealSSD P400m finishes towards the middle of the pack in the ATTO Disk Benchmark--it outpaced the Intel DC S3700 200GB drive in the Read test, but trailed the same Intel drive slightly in the Write test.
