5MB Hard Drive 1950s
Here’s something you don’t see everyday, a 5MB hard drive being loaded onto a plane. The IBM 350 Disk File, invented by Reynold Johnson, was introduced in 1956 with the IBM 305 RAMAC computer. This drive had fifty 24-inch (0.6 m) platters, with a total capacity of five million 6-bit characters (3.75 megabytes). A single head assembly having two heads was used for access to all the platters, yielding an average access time of just under 1 second.
