DASD/D.A.S.D. (Direct Access Storage Device)

Some information I found on the net:

"Mainframe disks are sometimes referred to as SLEDs (Single Large Expensive Disks). The term DASD (Direct Access Storage Device) usually refers to a mainframe disk, but is occassionally applied to any hard disk."


"Direct-Access Storage Device (DASD) IBM mainframe terminology for a disk drive, in contrast with a tape drive which is a sequential access device."
