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 2.34 version of the program, but the benchmark is still limited to non-linear samples up to 256MB. ATTO Disk Benchmark requires that an active partition be set on the drive being tested.

While the bandwidth results are not realistic for determining the maximum drive speeds, ATTO Disk Benchmark is still a good tool for illustrating bandwidth using various file size chunks. Please consider the results displayed by this benchmark to be basic bandwidth performance indicators.

Our basic I/O bandwidth tests begin with the Seagate Cheetah 15K.7 hard drive connected to the LSI SAS3081E-R Serial Attached SCSI 3.0 GBps PCI-Express SAS adapter, as the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 600GB ST3600057SS model reveals a 204 MBps read plateau from 8-8192 KB file chunks (which is nearly the entire range), while the 203 MBps write performance plateaus from 128-8192 KB.
