I am considering purchasing a NAS nextweek. I chose synology ds411j for economic reasons. My current setup is a USB 3.0 single drive enclosure. I am getting tired of replacing drives with new ones for writing more data from the Tivo. This will also allow me to use ethernet transfer instrad of usb. Currently have 35 Mb internet which will be downgraded to 15Mb soon. Anyone else using a nas for download/upload to Tivo and happy with their coice? I have the premeire xl tivo. Thanks for any input.
