I use a Samsung M3 portable 1TB drive and the cable is a little short but now I have my QU-16 in a Studiospares mixer rack case the drive just hangs down the side of the mixer in the case – just don’t put the mixer down with it still there! I love the fact it records everything since I don’t have to think about it apart from arming and pressing play and since it works as an insert on each channel I can set the gains correctly for recording and then the faders set the FOH level. Excellent.
