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 new WD Velociraptor 1TB drive once again led the pack in the HD Tune benchmark in terms of bandwidth. Read and Write access times were also very good, although the Seagate drives and WD RE4 offered somewhat better Write access times.
