It is hard to imagine – on September 13th it will be 50 years since IBM introduced the very first hard drive.
Since that time technology made quite a progress. Compare for yourself:
1956 – RAMAC drive
- capacity: 5 Megabytes, built from fifty 24″ spinning disks
- weight: about one ton
- price: $250’000 / year (lease)
- price per gigabyte: about fifty million dollars
2006 – typical harddrive
- capacity: 500 GB
- weight: < 1kg
- price: ~ $300
- price per gigabyte: about 60 cents
Amazing, isn’t it ?
