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). In the top panel, an IBM engineer holds a magnetic tape strip on which approximately 200,000 characters of information can be stored on an IBM 2321 Data Cell Drive. Two hundred such strips were contained in a data cell and 10 interchangeable cells could be mounted in the vertical drum seen in the drive (at right). IBM 2321 Data Cell, eight units maximum.
