Try to guess what this is…
Here’s the answer:
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.
If 5MB of stored data weighted over a ton, then that is over 200 grams per KB! If data storage technology had not developed since 1956, my laptop’s hard disk drive would weigh over 16,000 tons!
