@jarledb I bought one of these cards: https://www.pbtech.co.nz/product/MEMSAM12120/Samsung-Pro-Endurance-64GB-PRO-Endurance-Micro-SDX
Really enjoying the camera. The DR750 writes enough data to fill the 64gb card in under 24hrs so I can see why my Sandisk card cooked itself. Yes it was the white car!
@sonyxperiageek That is what I was using but writing a 1080p 60fps + a 1080p 30fps stream to it for hours a day cooks it.
