e/Hard Disk 20SC

Information
has gloss	eng: The Apple Hard Disk 20SC (not to be confused with the Apple Macintosh Hard Disk 20, the first hard drive manufactured by Apple exclusively for the original Macintosh floppy disk drive port interface) was Apples first SCSI based hard drive for the Apple II family as well as the Macintosh and other third party computers using an industry standard SCSI interface. History Released in September 1986 along with the Apple IIGS (which required an optional SCSI interface card), it debuted over 9 months after the introduction of the Macintosh Plus, the first to include Apples SCSI interface. It was a welcome addition at considerably faster data transfer rates (up to 1.25 megabytes per second) over its much slower predecessors, the Hard Disk 20 (500 Kilobits per second) and ProFile (which could only be used with the Macintosh XL).
