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. 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 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).

The IBM 2321 Data Cell announced in April 1964 (withdrawn January 1975) is a direct access storage device for the IBM System/360.It holds up to 400 megabytes of data, with an access time of 95 milliseconds to 600 milliseconds, depending on the addressed strip position and data arrangement in each data cell. Oct 28, 2015 - IBM 2321 Data Cell, 1964, held 400 MB of direct access storage on magnetic tape.
