I expect that SCSI won't give the performance boost you expect.  I suggest
that you do a test of same size and brand IDE and SCSI drives to find out
which is best if you plan to install a number of machines.
As for "striped mirrors", this usually means RAID-0+1 AKA RAID-10.  RAID-10
requires a minimum of 4 hard drives (2 minimum for each striped set and then
double that for mirroring).

Chances are that a pair of good fast hard drives running RAID-1 mirroring
will provide all the performance you need...
