The IBM 1311 Disk Storage, announced in 1962, featured IBM 1316 removable disk packs, one of which is being held by the man. The lowest cost IBM 1311 was priced at $17,000 ($130,000 if inflation-adjusted to 2012). To good approximation, each disk pack weighed 10 pounds, occupied 210 cubic inches, and sold for $490; it had a data capacity of 25,000 punched cards, which would have weighed 200 pounds, occupied 8,000 cubic inches, and sold for $50. Thus, a disk pack was 20 times lighter, 40 times smaller, and 10 times more expensive than an equivalent number of punched cards. Courtesy IBM Corporate Archives
