Well, if you're a freak like me and have multiple devices, it can be nice
not to have them all arguing with each other...
a 4 U160 drive RAID cage would generate some amount of bus traffic,
approx 100M+ which is more than any easily available tech other than
U160 and Fibre Channel (anyone know the specs on that) can
manage..
spose one can have the same argument about U100 ATA and the fact
that the fastest IDE drives only do 7200..
