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 IBM 2321 data cell drive IBM 2321 Data Ccell Drive IBM 2321 Data Cell Drive * Announced April 7, 1964 and withdrawn January 6, 1975 Known as the MARS file through much of its seven-year development, the IBM 2321 Data Cell Drive was a random access device that could store up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. 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.
