Well SCSI is better from the technolgy, but ...... unless you get one of the DMA-enabled kind SCSI will eat CPU-cycles just like IDE. And remember, you can get a 400GB IDE-HD brand new for the price of an 4GB used SCSI drive. You might even have enough spare to get a CD/DVD-drive. Or even better, get an CF-card + adapter. The fast access times will make good for any missing transferrate (and it's quite).
Downside is your limited in the number of devices.
