what's an SCSI?

and remember, when you open up a bunch of tabs, reload.

Small Computer Systems Interface.

A interface for harddrives and other peripheals, instead of the AT/IDE bus and for example the parallel port.
Can be used for a various array of peripherals but is mainly used for disks.
Previously RAID was exlusive for SCSI (Redundant Array of Inexpensive Disks) but now you can do that in IDE with a RAID controller aswell.
The SCSI interface is smarter than IDE and has some inbuilt logic circuits that made it faster in shuffling data and SCSI disks where generally faster and larger than their ATA counterparts.
The differences are lessening all the time.
