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.

Although the deltas are quite small, the OCZ Octane trailed the other drives in read throughout with block sizes smaller than 32K. With larger block sizes, however, all of the drives are tightly grouped in terms of read performance.

Writes are a different story, though. Once again, the SandForce-based drives led the pack in writer performance. The OCZ Octane outpaced the Crucial M4, but Samsung's 830 Series SSD was a notch faster.
