I agree.

That is true. What you are looking for are NAS solutions (network area
storage) that allow many computers to connect to the same storage device,
usually by NFS. They also usually connect by 100/1000Mb ethernet
connections. Those are basically regular servers running either Linux or
Windows with a CPU, RAM, etc. optimized for disk intensive purposes, and
chucked into a 1U or 2U rackmount case.
