File benchmark

The file benchmark measures the performance for reading and writing files to the selected hard disk partition with different block sizes ranging from 0.5 KB to 8192 KB (x-axis).
The length of the test files can be set. For accurate results a large size is recommended. If the file length is too small the hard disk may be able to cache the entire file. In that case the cache speed will be measured instead of the hard disk throughput.

On some configurations it may be neccessary to add a delay between the write and read test to make sure all data is written to the disk before the read test is executed.

This test is non-destructive but requires a partition with a drive letter associated.
