HD Tune Pro
HD Tune is a Hard Disk utility which has the following functions:
Benchmark: measures the performance
Info: shows detailed information
Health: checks the health status by using SMART
Error Scan: scans the surface for errors
HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.
The RAIDed pair of Corsair Performance 3 drives blows everything away when it comes to sequential reads. Here we see the Performance 3 drives in RAID 0 reading across the disks at very high speeds. It's hard to believe we hit over 800MB/s on the Sandy Bridge chipset so easily.
The write speeds on a single 128GB Performance 3 are quite a bit slower than the read speeds and that carried over to the pair of drive running RAID 0. You still get higher performance with the RAID set than a single Performance 3, however.
It is important to remember that the Marvell controller Corsair used in the Performance 3 sacrifices high write speeds in order to perform a lot of background garbage collection activity.
