What is it?

 

Guess what it is?

This is 5MB HDD!!!

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 5 MB of data.

Currie Munce, research vice president for Hitachi Global Storage Technologies (which has acquired IBM’s hard disk drive business), stated in a Wall Street Journal interview[5] that the RAMAC unit weighed over a ton, had to be moved around with forklifts, and was delivered via large cargo airplanes. According to Munce, the storage capacity of the drive could have been increased beyond five megabytes, but IBM’s marketing department at that time was against a larger capacity drive, because they didn’t know how to sell a product with more storage.
