The 50th anniversary of shipment of the first hard drive will occur this
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".
RAMAC = Random Access Memory Accounting System
