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)
ATTO Disk Benchmark: Queue Depth 10
Our basic bandwidth speed tests begin with the OCZ RevoDrive 3 X2 PCI-E SSD installed into the Intel P67-Express motherboard's 8x PCI-Express port. Using the ATTO Disk Benchmark tool, the test drive performs file transfers ranging from 0.5 KB to 8192 KB. This 480GB model RVD3X2-FHPX4-480G reveals 1568 MBps maximum read speed that plateaus from 1024-8192 KB file chunks, and 1402 MBps peak write bandwidth plateaus from 512-8192 KB. These results both exceed OCZ's own specifications of 1500/1250 MB/s for the RevoDrive 3 X2. Using a recommended ATTO queue depth of 10 the performance results increase to 1580 MBps read and 1413 MBps write.
