Hard disk turns 50 and the floppy dies

Again from a forgotten source

The 50th anniversary of shipment of the first hard drive occurred on Wednesday, September 13, 2006.

The original hard disk drive (IBM 305 RAMAC) in 1956 stored only 5MB of data on fifty 24-inch disks and weighed over 250 kg (over 550 pounds). About the size of two large refrigerators and as tall as a man, you could lease the whole unit for about $250,000/year in today’s dollars and not quite store two mp3 copies of Elvis Presley’s “Hound Dog”.

Of course the hard disk didnt hit the PC world until much later! Early PCs had floppy disks – smart models had two – one for your word processor or similar program (which believe it or not would fit on a 64k disk) and one for your data.

The PC hard disk appeared in the mid 1980s. I remember the advertising campaigns in Egghead and similar stores “Real men don’t have floppy disks”…

Whether due to functionality or egos of owners, hard disks took off. By 2006 floopy disks have all but disappeared.
