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 3TB Seagate Barracuda XT 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 ST33000651AS model we received reveals 108 MBps maximum read speed that plateaus from 8.0-8192 KB file chunks, and 108 MBps peak write bandwidth plateaus from 8.0-8192 KB.
In the next section, Benchmark Reviews tests sequential performance using the CrystalDiskMark 3.0 software tool...
