Disk Bench tests your hard drive speed in a real life situation not in a benchmarking environment.
To perform this test, the program copies a selected file from A to B and measures the time it took. When the test is done, it can automatically delete the copied file from location B.
Disk Bench can be used with a single file, and entire folder or you can run a benchmark by creating a file with a user-specified size.
In addition to measuring transfer speeds (read/write), the program can also perform a read-only test.
