Using Multible Hard Disks?

Currently I have 4 Hardisk 1 for Movies , TV Shows , Anime & Youtube Vids . at the moment I am using a 4 port usb hub with 4 power on/off switchs to browse each drive one at a time What I was wondering " sorry if Dumb question as I am not computer savvy" If I purchase something like will I be able to see at the drives ? or maybe a 4 Bay Nas enclosure? Thanks


I know for sure that it will recognize a NAS drive but i have never tried a Sata to USB enclosure.
