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 AMD Radeon R7 Series 240GB SSD led the pack with regard to write performance in the HD Tune benchmark, though reads were about average. The AMD Radeon R7 Series 240GB SSD's access times were also quite good here.
