I use a simple 2.5" external usb drive connecter to my router as a shared drive on my home network. I also use it to run my router’s torrent download tool and get new content.

The external drive is not new and I worry that with the constant load it might fail one day. It’s also slow sometimes when watching content directly from it with kodi.

What would you suggest I replace it with? Would a 3.5" external usb drive be safer?
