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.
