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.

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 in the field. The IBM 2321 Data Cell Drive.
When the 2321 data cell was discontinued in January 1975, the addressing scheme and the device itself was referred to as CHR or CTR for cylinder-track-record, as the bin number was always 0. IBM refers to the data records programmers work with as logical records , and the format on disk as blocks or physical records .

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. 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 in the field. 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 standard offering was a 2841 SCU with a number of 2311 DASD up to eight. 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 System/360 System Summary (PDF).
The 2321 housed up to ten removable and interchangeable data cells. 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.
