IBM’s 1st Hard Drive 1954
These 50 stacked 24”-diameter platters could have held about 2 iTunes songs.
(The total capacity was 5MB.)
Comparing microdrives with the 1st IBM hard
drive:
 A 1-inch 8GB platter holds more than 80,000 times as much data as a single 24inch RAMAC platter.
 An 8GB 1-inch drive holds 1,600 times as much data as RAMAC.
