I'm trying to figure out a good - and inexpensive - way to store data so that it can be easily shared by all the computers on my home network. I have a desktop, three laptops and a phone that are all on the same home network and I'd like them to be able to share videos, music, documents easily. The desktop is running XP, the laptops are running Win 8.1 or Win 10, and the phone is Android. Ideally, I'd like the storage to be external to all of the devices but visible to all. I suppose I'm looking for an external hard drive that can be readily accessed by each of the devices. I have a 3 TB drive in the desktop that could be the starting point for this. I don't expect the data on the shared storage to be accessible to all devices except when I'm at home but I'd like to avoid having to have wires joining everything together when I am at home. I can live with the phone NOT having access to the shared data if that's too hard to do. Suggestions?
