I need info on NAS for iTunes. I have a MacBook Pro 2013 8GB RAM 250GB internal Flash drive. I'll be using the wifi NANO DAC. I don't need a very large HD just about 1TB at most. I have look at I have an old NETGEAR router no usb connections Synology America DiskStation 1-Bay Network Attached Storage (DS115J) I mistakenly bought a 4TB WD at Best Buy for 125.00 USB3 was hoping I could use it with a Kanex Thunderbolt to eSATA + USB 3.0 Adapter for 80 bucks and save some money that way I could make use of my large WD external and it would also be powered.
