Can you guess what this is?

it’s a 1956 5MB memory storage IBM hard disk! in september 1956 IBM launched the 305 RAMAC, the first computer with a hard disk drive (HDD), the HDD weighed over a ton and stored 5MB of data, makes you appreciate your 32 GB USB drive, doesn’t it?

an IBM RAMAC 305 with a 350 disk storage unit was leased for about $3,200 per month back in 1957, over a thousand of the 305 systems (one of IBM’s last vacuum tube units) were manufactured before production ended in 1961, and the 305 was withdrawn in 1969.
