I worked for a company that manufactured disk and tape drives. The mainstay was a drive that was the size of a washing machine, that had a removable stack of 12” platters that sat on top, and could hold a total of 40mb of data.
We had those on our Burroughs 6800 mainframe. I think we had about 20 of them in some type of RAID config.
When the company I worked for finally stopped using what seemed like acres of those machines, your company probably went bust.
