The 'time' command can be used if you develop your own benchmark and have
on hand several devices which you compare with each other. My situation
is that I have a single CD-ROM drive and I want to see if it indeed has
6.7x the speed advertised for it. For this I need a standard benchmark
test. With published numbers for 1x, 2x, 4x, 4.4x, 6x, 6.7x, etc. devices.
(It had better not be a cheatware! :-) )
For my hard disk, I used (under MS/DOS) the Norton SI program and it
served very well my limited goal - that of proving that installing
another device on the SCSI bus did not degrade the performance of the
first device.

Cheatware, n.:
Software which has attractive man-machine interface and which makes you
believe that it does something that it does not actually do. Example:
some brands of RAM doubler software.
