United StatesThe best memory card I have used.
Great product, super fast, the best memory card I have ever used.
United StatesWhat a CFExpress card should
Reliable, fast and meets specifications. Excellent card with a Nikon Z9 or Nikon D850 (updated firmware). Meets specs and expectations. Bought more, and all great. Good metal wrapper.
United StatesFast & reliable - though hot when busy
Overall, this is a terrific memory and it is plenty fast for demanding high-speed photography and video. It will - as advised - get pretty hot to the touch, but this seems to be within the specification and I’ve seen no problems with this. So far, no data flaws or read/write issues at all, so my experience has been great.
