Really a “big” harddisk


Tags: , , , , , ,

Still complain that the 3.5-inch mobile hard drive is inconvenient to carry or cloud space isn’t enough? This IBM 305 RAMAC (Random Access Method of Accounting and Control) presumably can completely change your mind. Did they move the furniture? This behemoth in 1956 that is composed of 50 24-inch disks is 16 square feet and more than one ton weight, in addition to the fixed U.S. $ 35,000 per year for maintenance and operation, it’s only 5MB of storage space.

wow amazing surprising old big IBM hard disk
