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.

Although our ADATA drive was a mite slow out of the gate in the write throughput test, it hung with the lead dogs in larger transfer sizes, starting at about 32KB. By the end of the read test, the XPG SX900 was part of the top cluster of scorers, although between 4KB and 64KB transfer sizes, non-SandForce controllers outpaced its performance for the most part.
