5 MB hard disk!

The Volume and Size of 5MB memory storage in 1956.

In September 1956 IBM launched the 305 RAMAC, the first computer with a
hard disk drive (HDD). The HDD weighed over a ton and stored 5MB of data.



The IBM 350 Disk Storage Unit provides storage capacity of the disk drive
was 5MB (referred to at the time as 5 million characters). It was configured
with 50 magnetic disks containing 50,000 sectors, each of which held 100
alphanumeric characters.



With the cabinet covers on, the IBM 350 Disk Storage Unit measured 5’ 8”
tall, 5’ wide and 2’ 5” deep, whilst it weighed in at massive 250kgs. The unit
comprised fifty 24” platters, one pair of read/write heads and a pulley system
that provided both the vertical and horizontal head movement.
