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.
As you can see, the Samsung SSD 750 EVO held up nicely against the 850 EVO and other SSDs we tested, and even bested the 850 in a few instances.
