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.
We saw much of the same in the HD Tune benchmarks. The new MX100 series drives compete well in read tests, finishing about in the middle of the pack. The 512GB also put up good write scores, though the lower-capacity 256GB drive trailed the other drives we tested.
