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 Intel 335 series SSD's performance in the HD Tune benchmark is somewhat of a mixed bag. The bandwidth offered by the drive trails other SandForce-based products in terms of peak bandwidth, but access times and utilization are down slightly.
