Hard drives on your PC might perform based on many parameters, but you can always set a benchmark for these performance and compare them whenever needed. DiskMark is a small freeware utility for Windows that allows you to benchmark your disks and hard drives performance. It allows you to specify many advanced options to determine how your drives perform best and also to determine the typical operating performance.
When you start the program, you can select the drive you want to bench mark for performance. The configuration dialog allows you to set the parameters of the disk benchmarking process.
DiskMark is a simple and yet useful tool to benchmark drives on your PC.
