EFD Software's HD Tune is described on the company's web site as such: "HD Tune is a hard disk utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more." The latest version of the benchmark added temperature statistics and improved support for SSDs, among a few other updates and fixes.
The Corsair Neutron didn't fare too well in the various HD Tune tests. In the sequential and burst tests, the Neutron trailed the Samsung and SandForce-based drives by a wide margin. The Corsair Neutron's access times were near the bottom of the group as well.
