   From the late 70s. Apparently, it’s from a storage device for IBM mainframes. Google for “IBM 1GB hard drive” and you should be able to get more info.

   When is then?

   Man, that is really big.

   … They should get a microSD card instead of the bulky regular one. ^_~

   Then would be sometime around 1990.

   Hard disks in 1982 were about 100MB for that size. The 5″ disks were 5-10MB.

   In 1990, you could get about 100MB on a 5″ drive. That big thing would have been about 10x the capacity.

   I didn’t work for IBM, so I have no information about that particular unit. It is rather unusual in that it has two head assemblies. Must have been made for the high performance market.

   Dunno, sorry. The source of the image didn’t have any more details, and the description on the exhibit in the picture doesn’t show much either.
