Ah the old IBM "sow FUD with obscure terminology and names".
OEM salesman: If you buy your disks from us you can save oodles of cash.
IBM user: What are these "disks" of which you speak? Anyway we don't have them!"
OEM salesman: Our disks are much cheaper and they are plug compatible; only your wallet will notice the difference!
IBM user: Begone! We don't need your "disks"!

IBM user: Our computers use the very latest and greatest Dynamic Access Storage Devices (DASDs), we don't need these "disks"!
OK, probably apocryphal but those were the days!
