- SCSI stands for Small Computer Systems Interface. This is an intelligent
- interface for connecting many types of peripherals to a computer, including
- hard drives, tape drives, CD-Rom drives, Floptical drives, ect. Being
- intelligent, the CPU does very little work (comparitively) getting data to
- and from the drive. In a multitasking system, this is a good thing.
-
- IDE stands for Integrated Drive Electronics. On this interface you can only
- connect hard drives, and typically only one hard drive, but at most only two
- (if you are luck enough to be able to get two IDE drives to work together
- in a master slave arrangement-there was a big discussion of this problem on
- comp.sys.amiga.hardware a while back). IDE drives are not as intelligent
- as SCSI drives, and the IDE interface tends to require much more CPU time
- then compared to a SCSI interface. On a system like an IBM-PC running MS-DOS,
- this does not matter, as the CPU has nothing better to do.
-
- IDE drives to have the advantage of being somewhat cheaper than SCSI drives.
- But if you shop around a bit, you can get a scsi interface and drive for
- your 2000 for the about the same price as an IDE interface and drive, and
- the SCSI interface will be more useful to you in the long run. Also, SCSI
- interfaces (2091 for example) tend to come with memory expansion capability
- on the board.
