The IBM Data Cell [noodle picker] was among several IBM trademarked "speedy" mass online direct-access storage peripherals (reincarnated in recent years as "virtual tape" and automated tape librarian peripherals). The 2321 file had a capacity of 400 MB, at the time when the 2311 disk drive only had 7.2 MB. It's more like a floppy - especially in its original version, the IBM 2321 Data Cell Drive of 1964 (see below). MagCards are a downscale from the 2321, which was, at its time the top end of random accessible online storage. They provide much larger storage than any punch card, and were introduced (1969) way before floppies in the early 1970s (*1).

The Drive was rotated under a Selector Station by a Vickers hydraulic motor.

IBM initially shipped the 2321 Data Cell Drive in 1965, a product designed to provide random access to data stored on Mylar strips coated with magnetic media. Panel members participated in IBM's long development program for the Data Cell system, with many problems in magnetic strip card manufacturing and in reliability of the drives installed
