IBM 2314: 29MB per (removable) pack.pfletch101 wrote: ↑Tue Jul 23, 2019 12:53 amOn a similar note, in the early 1980s, I was involved in some high level negotiations between my (clinical) department at a University hospital and the Bioengineering Department about the joint purchase of a 'large' hard disk for our joint use. The beasty in question was about the size of a washing machine, required an air-conditioned environment, and cost nearly $100,000. Its capacity? 80 MB!W. H.

He was ecstatic when he found a company that was bringing out a new line of HDDs with discounted introductory prices. He was able to get a 15MB drive for $985.HawaiianPi wrote: ↑Mon Jul 22, 2019 7:25 pmI think my first hard drive only had 20MB of storage, and you wouldn't believe what that cost.![]()
IBM 2311: 7.25MB per (removable) pack.
Both used 14" platters. The packs for the 2311 were 6 high (10 tracks per cylinder), and for the 2314, 11 high (20 tracks per cylinder). Those were both from the days when the head actuator was hydraulic, though the 3rd party "plug replacement" drives for the 2314 used a voice coil linear induction motor, where the coil was about 4 inches in diameter. Fun times...
