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 basic bandwidth speed tests begin with the OCZ Agility 3 SSD attached to the Intel SATA 6Gb/s controller operating in AHCI mode. Using the ATTO Disk Benchmark tool, the test drive performs file transfers ranging from 0.5 KB to 8192 KB. The 240GB model we received reveals 557 MBps maximum read speed that plateaus from 1024-8192 KB file chunks, and 524 MBps peak write bandwidth plateaus from 64-8192 KB. These both exceed OCZ's own specifications for the Agility 3 Series.

In the next section, Benchmark Reviews tests sequential performance using the CrystalDiskMark 3.0 software tool...
