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.
HDTune results show the Barracuda XT holds a small performance advantage over the Deskstar in average transfer rate. But the Hitachi drive offers better access times, with a more significant performance advantage in read access.
