Roon should work with most NAS drives, but we've found these brands consistently perform well. Mac users should check to see if a NAS drive can stream files to an Apple TV, or act as an 'iTunes server', storing your iTunes/Music library on the NAS drive so that it can stream music to every. Some NAS devices have wifi, and some allow the use of wifi if you connect a dongle to a USB port on the device. Your NAS could connect to your Mac via an Ethernet cable, and could be in the same room as your computer or it could be in any location as long as it can access your network. To set up and manage a NAS, you connect to it over a network.
