Up to eight 2321s could be attached to the IBM 2841 control unit, allowing an overall capacity of over 3GB. The IBM 2321 Data Cell Drive was a random access device that could store up to 400 million alphanumeric characters or up to 800 million decimal digits on magnetic strips mounted vertically around a rotating cylinder. The IBM 2321 Data Cell announced in April 1964 (withdrawn January 1975) is a direct access storage device for the IBM System/360.

The IBM 2321 Data Cell Drive was introduced in 1964, after years of development work, as a very large capacity storage system. The total storage capacity was about 400 Mb. The drive accomodated 10 removable and interchangeable data cells like the one shown above. Each data cell contained 200 2.25" by 13" magnetic strips.

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).

Thompson: 305. And, after that was finished, I went to work on a new program called the VLCM, Very Large Capacity Memory, which become the 2321 ultimately. So I was there pretty nearly in the first stages of the actual design of that thing. 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.
