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 Micron RealSSD P400m trailed all but the Intel SSD 710 series drive in the HD Tune transfer rate benchmark. Access times in the write benchmark were competitive, but the Micron drive stumbled here.
