The 350 Disk Storage Unit consisted of the magnetic disk memory unit with its access mechanism, the electronic and pneumatic controls for the access mechanism, and a small air compressor. 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.

a byte is one "character" and a megabyte is 1 million of them, so yeah they have a capacity of 5MB, which is roughly the capacity of 2 floppy disks

wikipedia has a good chart comparison;

fuk i cant paste it
