The hard drive IBM shipped in 1956:

• Stored five megabytes
• Cost $11,000 per megabyte *
• Was 60 inches long x 68 inches high x 29 inches deep
• Weighed about one ton

* about $121,819.66 per mb in today’s money.

The first two hardrives I had experience were not that big, but still required to people to get into the cabinet. A Fujitsu Eagle and a CDC I can’t remember which model that had 5MB fixed and 5MB removable.
