SCSI is more general purpose. IDE simply means "integrated drive electronics", i.e., the disk controller is on the drive. It is NOT a disk interface standard. The interface with which IDE drives are normally used is the standard AT interface. While there is some merit in the IDE versus SCSI argument, the real argument is whether SCSI is or is not better a more dumb interface. However, IDE versus SCSI is a false dichotomy, because two orthogonal things are being compared: (a) Where the disk controller is, and (b) How smart the disk controller is. -- Rahul Dhesi <dhesi@cirrus.com> also: dhesi@rahul.net
