SCSI Drive

a jumper diagram imprinted on the drive itself. For price and compatibility, I'd stick with IDE. With IDE, though, make sure the drive is UDMA. Most likely, your motherboard supports ATA-33,66 or 100. So, you may want to get a drive that can pump that hard. Get a drive with a decent rotation speed. 5400 RPM drives are slow. 7200 RPM is better, and higher RPM drives even better. The really fast drives, though, may require a hard drive cooler, so unless you are willing to mess with that, get a drive with a good balance of speed and temperature. If speed is your biggest concern, go for the SCSI interface. Keep in mind that with SCSI you will have to purchase the additional hardware necessary for the SCSI bus. Also, get the largest drive you can afford. You’ll be surprised how fast you can fill up a hard drive, depending on what you do with your PC.
