DASD DEFINITION (continued): … DASD, pronounced DAZ-dee (Direct access storage device), is a general term for magnetic disk storage devices. The term has historically been used in the mainframe and minicomputer (mid-range computer) environments and is sometimes used to refer to hard disk drives for personal computers. A redundant array of independent disks (RAID) is also a type of DASD. The "direct access" means that all data can be accessed directly in about the same amount of time rather than having to progress sequentially through the data.
