SATA III SSD Round-Up: OCZ, Corsair, Patriot, Crucial
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 overall ATTO Disk Benchmark results are ultimately tell the same story as our previous results, with the SandForce-based drives closely grouped together in terms of reads and writes, with the Marvell-based Crucial M4 mostly trailing the other drives. It's worth noting, however, with block sizes of 4K and smaller, the M4 has a slight performance advantage over the other drives tested here.
