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.
Our basic bandwidth speed tests begin with the G.Skill Phoenix Pro SSD connected to the Intel ICH10 controller in AHCI mode, as the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 60GB model we received reveals 286 MBps maximum read speed that plateaus from 128-8192 KB file chunks, and 273 MBps peak write bandwidth plateaus from 64-8192 KB. These both exceed SandForce specifications, and roughly match G.Skill's 285/275 MBps manufacturer specifications.
