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.

I think, I need to put this stuff into my collection 🙂 .
