EFD Software's HD Tune is described on the company's website 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 Intel SSD 660p 1TB drive we tested offered middling performance in terms of transfer speeds in this test, and its latency was somewhat higher than the other
Intel drives as well.
