First Hard Disk Made By IBM

IBM developed a gigantic 5 MB hard drive system for their RAMAC computer. Just imagine trying to cram this thing into an iPod. Or your house, for that matter... IBM invented the disk drive in 1956. The first disk drives were the size of two large refrigerators and held 5 MB. Storage cost $10,000 per MB (so your 20G drive would have cost $200,000,000 back then!). Today it's about 50c per GIGABYTE (or .05c per MB) The platters of disks typically spin about 100 miles per hour. 1 GB
