Summary: [25-9-2006] Last week saw the 50th anniversary of the very first hard drive.

Body: Happy birthday, hard drives. This week saw the 50th anniversary of the very first hard drive, the IBM RAMAC 305 (such a trendy name!), introduced in 1956.

The storage part of the drive was about 5' square and its capacity was around 4.4MB. Apparently the drive could have been given a larger storage capacity, but the IBM sales department didn't think they could sell the thing with more storage!

The entire RAMAC unit weighed over a ton and had to be moved around with forklifts and delivered via large cargo airplanes.
