The first hard disk - 50 years ago

Tue, 5 December 2006

In 1956 IBM invented the first computer disk storage system, the 305 RAMAC (Random Access Method of Accounting and Control). This system had a storage of 5 MB and it had fifty disks, each being 61 cm (24″) in diameter.

5 MB hard disk 1956

It wasn’t necessarily a very portable device, so maybe we should stop complaining about those ‘only 120 GB’ laptop drives.

Stumble it!

    Murphy’s law of sorts…
    Data expands to fill the space available to it.

    When we have large disks, we stop deleting stuff till we need more space.
    We also use them now for things we would not have dreamed of in the past. An hr of MPEG2 recording of a HDTV program would go up to 8GB. When the disks were more expensive, we were only using them for more important stuff.
