First Gigabyte Hard Drive: The IBM 3380 HDA - APHELIS
The first hard drive to break the one gigabyte barrier was the hard drive assembly made by IBM in 1980 for its new 3380 series.
In February 1985, IBM added two new model types to its 3380 family of direct access storage devices, offering up to a 15 percent increase in performance over the three standard IBM 3380 units. These new extended capability models were available in single capacity (AD4 and BD4) and double capacity (AE4 and BE4) versions.
The IBM 3380 Direct Access Storage offers increased capacity, improved access time and data transfer rate, and reduced storage costs to users of larger data processing systems. It features higher data densities, a number of engineering enhancements, and the …
