​Technically, it was because you could get to a particular "block" of data
"directly" (DASD == Direct Access Storage Device) as opposed to a "serial"
device like tape (no "seek" on the original tape drives). It definitely
was​ wasn't a "random access" device because of the seek time (the same is
true of all disk devices). SSD and Flash are possibly the only non-volatile
true "random" access mass storage devices at present. And I'm not totally
sure about them.
