But you have to admit that taking price into account really changes things. The fastest
IDE may be slower than the fastest SCSI, but its a lot cheaper. IDE would be a problem if
you decided to use a master and slave device on the same controller, but it works great
if you put one device per controller.

I had a file server with SCSI Quantums (SCSI) which started to die one by one (so much
for reliability). so they were ditched them and replaced by a raid array (RAID-5) of 4 x
45GB IBMs (ATA100).

The result was about 80GB of space and very fast access times, plus its been up for
months without trouble.
