Unlike SCSI, IDE/ATAPI is a storage device only bus, you can only connect storage devices, such as hard disks, CD-ROMs and ZIP drives to the IDE bus. By comparison, SCSI is a true system bus that can accept and communicate with numerous types of devices, including scanners, and other specialized devices.
Generally, IDE/ATAPI tends to be slower than SCSI, but it's also cheaper and easier to implement. IDE can only accept 2 devices per channel, while SCSI can accept up to 7 (or more) devices per chain. Recent Advances in IDE technology have pushed the speed of the IDE bus up to 100MB/s top speed. This puts IDE right up against SCSI when it comes to transfer speed. However, this does not change the fact SCSI is still capable of achieving a higher overall data throughput.
