It is a  5 MB Hard Disk Drive   for the IBM 305 RAMAC, the first IBM 'SUPER' computer released in September 1956.
  
This  HDD weighed over a ton and stored an 'astonishing' (@ the time) 5 MB  of data.

  Do you appreciate being able to reach into your pocket & pull out your 16 GB  memory stick now - or perhaps even your 4G iPhone with 32 GB of memory?!? 

 Something to think about, huh?
