It's a hard disk in 1956....

The Volume and Size of 5MB memory storage in 1956.

The IBM RAMAC 305 system with 350 disk storage leased for $3,200 per month in 1957 dollars,
equivalent to a purchase price of about $160,000

It had fifty 24-inch diameter disks
The HDD weighed over a ton and stored a whopping 5MB of data.


Kind of makes you appreciate your 4 GB jump drive, doesn't it?
That's 4000 MB of data and costs less than $100 to purchase.
Weighs less than one ounce
