The IBM 3330 Data Storage (seen
here in a design model) was a high-performance,
high-capacity direct access storage subsystem for
use with all IBM System/370 models as well as the
IBM System/360 Model 195. Each 3330 subsystem could
have from two to 16 drives, giving users up to 1.6
billion bytes of online storage. Developed and manufactured
at IBM's facilities in San Jose, Calif., the 3330
was announced in 1970 and withdrawn from marketing
13 years later.
