OWC480GB Atlas Pro High Performance Cfexpress 4.0 Type A Memory Card Professional Grade, up to 1850MB/s Read and 1700MB/s Write Speed

To be brutally honest, I was a little skeptical on buying a brand name that I wasn't fully familiar with, but this turned out to be a good choice for me. I shoot on an A7R5 and usually do portraits/weddings, but occasionally I like to shoot sports and needed a faster card because my buffer was filling up fast. This card sped up my write time and helped keep my buffer clear when I'm shooting baseball in burst mode. I can run off 15 shots on a 61 MP camera in RAW and it clears my buffer quickly. I did not do time trials or measure speeds, but after using SD cards forever, I can say that this was a definite improvement. I only have the one at this point, but I can see myself getting more of these in the future to use for everything.The storage capacity of the card is great at 480 GB, it gives me plenty of space when I'm shooting RAW+JPEG (small) to take hundreds of images without worrying about filling up the card.Quality is great, card feels solid and has produced excellent results for all of my uses.For video, which I do occasionally, it allowed me to use the S&Q settings on the A7R5 which weren't available with SD cards for shooting in slow motion.Overall, it's been great for the length of time I've had it and would definitely look to buy another one soon.

Fast reads and writes and no problems

Owc you’ll never go wrong good price too

Got this card at a very good price. Performance is amazing, as it should be.

Used it and filled it and copied it off about 10x now no errors. Used as a single card but am tempted to get another as a dual card. Speeds as advertised. Good value with adapter, speed and capacity. Sony A1 Raw, 8K video at highest rate, and S&Q mode all worked. Have used in hot environments and although warm did not thermal shutdown.

A main reason for me to choose this OWC card over its competitors is because it comes with a Type B adapter. I only owned a Sony camera with Type A card slots but occasionally rent other cameras that support Type B cards. It's not mentioned explicitly. But I have assumed that the adapter would allow it to work on things like Canon or Nikon. Unfortunately, it does not, at least for the Canon R5 II I just rented. With the adapter, the camera shows it cannot be used (not be able to format it at all). The website description should be explicit that the Type B adapter is not widely compatible.

Wow! I hit a Jackpot with this, I never knew it's comes with an adapter for CFExpress Tybe B, so CFExpress Type A and Type B(with Adapter).I was so happy since I own Cameras with CFExpress Type B and have Type B card readers I didn't need to buy Type A reader.That was a pleasant Surprise.

For some reason the card isn’t reading almost at all. When I click on it in file explorer, it freezes my whole computer. I can’t even transfer files from it because it just freezes. Turns out OWC forces you to buy their card reader just to be able to update the card through their app Innergize. I feel so robbed.
