Why u need 40 tb?

I don't need 40TB now, but at one time, before I knew more about streaming, I did.
I'm a librarian, I collect books, pictures, movies, porn, and apps... not necessarily in that order.

Lately, I've been using Kodi, and don't need so much storage as in years previous.. ;-)

I think has gone now for keeping aps anf porn in disks now, time is now for streaming

I agree most people don't need 20TB of storage.
What most people need, is a way to organize 5-10 drives they collected over time, and be able to search them for important files.
