Corsair Force GT 240GB & Crucial M4 SSD Update
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 Corsair Force GT 240GB drive once again offers best-of-class performance in the ATTO Disk Benchmark. The Crucial M4 also shows a huge increase in write performance here. Its write speeds, however, are only marginally increased with the smallest of block sizes.
