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.

1956, 5 MB

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

1980, 2.5 GB

1980 – 2011, from 2.5 GB to 2 TB

Thanks :)
