I am looking for a Gigabit Ethernet NAS that can read/write data at 90MB/s for sustained periods of time. Thing is I am stuck between a Drobo or a QNAP. This will be used for Time Machine Gigabit LAN to four computers, Bittorrent, remote access and media streaming via Mac, Windows and Popcorn Hour. Anyone with a good/bad experience with either? Note: Popcorn Hour A-110 can only serve files at 2.5MB/s regardless of HDD or router used.
