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.
According to HD Tune, the Samsung SSD 830 Series drive is the best performer all around. In this series of tests, the Samsung SSD 830 Series drive offers the best Read and Write throughput, access times, and Burst rates, although CPU Utilization is high during Read operations versus the other drives.
