This picture was taken in 1956.
It's a hard disk drive with 5 MB of storage.
In September 1956, IBM launched the 305 RAMAC, the first 'SUPER' computer with a hard disk drive (HDD). The HDD weighed over a ton and stored a "whopping" 5 MB of data.
Do you appreciate your 8 GB memory stick a little more now?
