Integrated Device Electronics (IDE)
IDE is the standard hard drive interface for PCs. You can connect a maximum of two hard drives to an IDE connection or channel. IDE hard drives are cheaper than SCSI drives, but IDE is generally slower than SCSI and does not support sector re-mapping.
Small Computer Systems Interface (SCSI)
Pronounced “skuzzy,” this is a standard data pathway used mostly for hard drives and CD-ROM drives; but it was also a common interface for scanners and even printers at one point. It is the fastest (and the most flexible) method of interfacing with hard drives. It comes in numerous varieties, and is mainly used in servers and high-end workstations. SCSI drives are much more expensive than IDE drives, but SCSI drives can have features, like 15,000 RPM spin speeds and 5-year warranties, that IDE drives currently do not.
