your cards may be vulnerable to premature wear from small writes
The common write speed of V30 is based on big writes. For small writes, you need A1 or A2 cards. When the video does one big write, the OS might do a dozen small writes and that kills cards that are not at least A1.

I tested a bunch of medium priced "Endurance" cards and there was no indication of any being better than the $5 cheaper non endurance version from the same brand.

In Australia, our consumer laws provide better protection against substitution of used and reject cards by shonky suppliers, provided you buy from an Australian shop or Web site. I suggest you look at buying from the manufacturer or a shop with a reputation to protect.

How good is the cooling for those cards? I see some installation where the microSD card is forgotten and gets no air flow.
