Hard Drives

What is the difference btween IDE Drives and SCSI Drives ? I noticed that the IDE
drives are cheaper.
1 Solution
SCSI - Small Computer Systems Interface.
IDE - Integrated Drive Electronics.

The difference between the two, essentially is how the disc itself is controlled.

The differences in price can be attributed to:

A single chip VLSI implementation of IDE costs about 1/10th the cost of SCSI.

An IDE host adaptor costs as little as 1/th to 1/20th the cost of SCSI.

Economies of scale also contribute to IDE drives being cheaper, There's a whole lot more IDE drives made than SCSI.

What you are able to use depends on the controller Apple gave you with the Mac you own.
on the other hand scsi drives are often more reliable and sometimes faster. But your choices are pretty much what kind of mac you own though older macs have a scsi connector on the back - but it is also a slower version of scsi than could be internal.
