CD Bench (no install)

Small, fast and reliable benchmark for CD-ROM drives. High resolution
timing (0.1 ms), 99% of asm code, 100% freeware.
Many people think that the data transfer rate of CD-ROM drives is
constant from the beginning to the end of the disc, but this is true
only for old-and-slow models. CD-Bench is the only benchmark that reads
the disc in six different points and displays six results, so you can
see if and how the speed varies.
