What was the IDE drive (would be interesting to compare the

Beware, that's a quite old technology drive (I don't think DCAS
are made any more). For approximately the same price of the DCAS
one year ago now there is the DDRS drive (4 GB) which does
12 to 13 MByte/s, which would make your SCSI controller obsolete
already :)

Personnally I hate IDE because of the limitations and the feeling that
it is of less quality than SCSI, the fact it's non portable, etc.
I have been migrating data for the last 8 years from different
OSes and hardware using SCSI drives (tar) or SCSI tapes.
With IDE you are pretty much stuck with PCs.
