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 Kingston HyperX Predator PCIe SSD leads the pack in HD Tune's average transfer rate and puts up some nice access times as well. Burst rates were nothing spectacular, however, and CPU utilization is relatively high--though that is to be expected with a higher performing drive.
