This is a real 3.78 gig hard drive from the 70s and it shows just how much we have advanced technology over the last few years.

 

This is a late 70's early 80's hard drive, it weights 80 pounds, and has a whopping 3.78GB. It cost 250K, and was used by banks to store account data.

This is the input for that Halon gas that the drives where filled with while in operation. Halon gas is a deadly gas that is pumped into the drives that makes them fire-proof, if there was a fire, the room they where in would be filled with halon gas as well, giving any operators in the room only one minute to get out.

Halon gas is not deadly!
It is 100% inert but contain no oxygen so when it displases normal air we choke.

It may be inert but choke = death therefore Halon is a deadly gas.

OK which is it, 30meg or 3.78gig ?..... pic#11 shows.... "300 400 gig HD sitting inside this 30Meg 80s drive" ....which makes a lot more sense than the captions claim of 3.78 gig. This was early 80s after all.

No way this is 3.78gig, I doubt all the computers in the world even reached that number at the time.
