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 bandwidth speed tests begin with each drive attached to the Intel P67-Express SATA 6Gb/s controller operating in AHCI mode. Using the ATTO Disk Benchmark tool, the test drive performs basic file transfers ranging from 0.5 KB to 8192 KB.
Seagate Desktop HDD 4TB ST4000DM000 (Four-Platter)
Seagate Barracuda 3TB HDD ST3000DM001 (Three-Platter)
Seagate Barracuda XT 3TB HDD ST33000651AS (Five-Platter)
The 4TB Seagate Desktop HDD model provided to Benchmark Reviews for testing produced 140 MB/s maximum read/write speeds that plateau very quickly from 8-8192 KB file chunks. These results approach Seagate’s performance specification of 146 MB/s this hard disk drive.
In the next section, Benchmark Reviews tests sequential performance using the CrystalDiskMark 3.0 software tool…
