DRSP is a program that tests the write and read speed of any drive by performing a series of DOS I/O operations. It allows you to adjust test parameters and log the results.
Drive Speed uses the most common sequential write and read operations performed via DOS functions 3fH and 40H. The results are displayed in kilobytes per second and MegaBytes per minute. It also tests file access speed and presents the results in operations per second. There are several test parameters that can be adjusted, and the results can be logged to a text file.

The program can test any drive - physical or device driven. If the drive is write protected (CD-ROM), DRSP can be run in one of two read-only modes
