The first computer hard disk drive weighed over a ton and had only 5 MB of storage capacity

Amazingly, the first computer hard disk distributed by IBM in 1956 weighed over a ton with only 5 MB of storage capacity. A hard disk today comes with 2 TB of storage and the weight is measured in grams. Here is the evolution of computer hard disk drives from 1956 to present days.

Just imagine, you’d need 6,554 hard disks like this one above to match your iPhone’s storage of 32 GB. Thankfully, storage technology improved over time.

1979, 250 MB

Just imagine if a modern day storage device were the size of that first one. How much data could it store? Every song ever recorded? The mind boggles!

Cool to look at but, at the risk of being a smart arse 185 x 5MB = 925MB, which is not even 1GB. A Quick check on the old calculator gives more than 6500 5MB devices to get to 32GB.

You`d need a warehouse to put them in, Just incredible!

You’re still way out! It takes 51,200*5MBs to make 32GB.
