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.

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 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 strips of magnetic tape, which were the basic recording media. The total storage capacity was 400 million bytes or 800 million decimal digits. Up to eight 2321s could be attached to the IBM 2841 Control Unit, allowing an overall capacity of over 3 GB. IBM 2321 DATA CELL DRIVE Alan F. Shugart and Yang-Hu Tong IBM Corporation, Systems Development Division San Jose, California INTRODUCTION Ten years ago IBM announced the 305 and 650 RAMAC Data Processing Systems systems that heralded the on-line processing concept, wherein business transactions could be economically processed as they occurred. In April, DPD demonstrates the IBM 2321 data cell drive in Washington, D.C. The division announces on April 16 the IBM 2415 magnetic tape unit and IBM 2540 card read punch, both of which are designed for use with the IBM System/360.
