ATTO Disk Benchmark
The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.
ATTO Disk Benchmark: Queue Depth 4 (Default)
Our bandwidth speed tests begin with the Crucial M500 solid state drive attached to the Intel P67-Express SATA 6Gb/s controller operating in AHCI mode. Using the ATTO Disk Benchmark tool, the test drive performs basic file transfers ranging from 0.5 KB to 8192 KB.
The 480GB model provided to Benchmark Reviews for testing produced 539 MBps maximum read speeds that plateau from 128-8192 KB file chunks, and 445 MBps peak write bandwidth that plateaus from 32-8192 KB. These results confirm Micron's performance specifications of 500/400 MBps for all 480/960GB Crucial M500 SSDs.
