That's quite difficult to say as there are several flavours of scsi.
The fast scsi 2 50 pin onboard the pci macs maxes out at 10MB per sec in
theory and 50/68/80 pin drives will not improve this - faster scsi
requires a pci card which come in 20/40/80/160/320 MB per sec speed
linked to price. Then there are raid arrays......
Similarly the drives have to be capable of the speeds required by
the card - so a 20MB per sec max drive is 20 MB per sec even on a 160
controller. I don't think there's much in the price - you can buy a cheap
U2W scsi PC card and flash it with the mac rom for a song - and you have
80MB per sec if you have the drive - and they're quite reasonable on the
auctions.
I'll leave the ide to someone who knows more about it.....
