Questions about this item

Does the V30 rating mean the card runs hotter during long 4K recording sessions?

The card is temperature-proof and shock-proof, so it handles sustained 4K capture without overheating concerns.

My camera only takes UHS-I SDXC cards — will this 2-pack work straight away?

Yes, both cards are UHS-I SDXC and compatible with Canon, Nikon, Sony and other brands that accept SDXC.

Can I mix these 64 GB V30 cards with my older Class 10 cards in the same camera?

They work alongside Class 10 cards; the camera will simply use each card at its own rated speed.
