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 2TB Samsung SSD 970 EVO Plus put up strong read performance with HD Tune’s workload, but ultimately trailed the 1TB drive by a couple of percentage points.
