I’ve not yet had the chance to test the SQ-Drive as we are running our SQ-5 on it’s first show but we own a Qu-24 and Qu-16 and have had a number of failed recordings over the last few years mostly on our Qu-16
It’s a great feature but if it’s that critical that you would consider a different desk you should have a backup device for recording regardless.
What I will say is that in the short time I’ve had the SQ and using it on its first job I don’t want to take the Qu out anymore and I’m going to upgrade my other desks to SQ’s
