Detailed explanation-1: -Today, the IBM System Storage® DS8700 is a hard-disk-based storage system from IBM and a direct descendant of the 305 RAMAC. One DS8700 cabinet is almost the same size as a disk storage unit in RAMAC, but it can hold up to 2048 terabytes of data-more than 400 million times the capacity of RAMAC.
Detailed explanation-2: -As of May 2022, the largest hard drive is 26 TB (while SSDs can be much bigger at 100 TB, mainstream consumer SSDs cap at 8 TB). Smaller, 2.5-inch drives, are available at up to 2TB for laptops, and 5TB as external drives.
Detailed explanation-3: -Assembled with covers, the 350 was 60 inches long, 68 inches high and 29 inches deep. It was configured with 50 magnetic disks containing 50, 000 sectors, each of which held 100 alphanumeric characters, for a capacity of 5 million characters.
Detailed explanation-4: -The original 305 RAMAC computer system could be housed in a room of about 9 m (30 ft) by 15 m (50 ft); the 350 disk storage unit measured around 1.5 square meters (16 sq ft).
Detailed explanation-5: -It stored about 2, 000 bits of data per square inch and had a purchase price of about $10, 000 per megabyte.
