The Critical Review posted:Hot Card, Almost too Hot to Handle! ByBobI had the same issue, with a different card reader than he used. I transferred just 3 images to the computer, which read out super fast, no issues. But while I was on the computer doing something else, I left this card in the reader for about 10-15 minutes before taking out. It was hot, though nothing was being transferred either way on it.I wasn't sure if it was the card or reader? But having this same issue, on two different readers makes me wonder. I'm thinking that maybe when the card is in a reader, it is in a constant ON mode whether transferring images or not, so card heats up. There is a marketing comment about using it over 20 minutes at a time due to heat, so maybe that's the ... MoreThe Critical Review posted:Hot Card, Almost too Hot to Handle!

There is a marketing comment about using it over 20 minutes at a time due to heat, so maybe that's the reason?The card transfers very fast, I have no complaints with it, so I will use in the reader only while transferring files, then remove right after. With my XQD card and reader, I could just leave the card sit in there, but I can't with this card.

This card is fast and it doubles the storage capacity of my previous XQD card. I also like the stiffer case used here. SD cards and the older CF cards had some flex to them which sometimes caused problems. I am very pleased with this card. It fits in an XQD card slotr but may not work with older readers. If you are using both XQD and CF Express cards with a reader, make sure the reader will handle both types of cards. A problem was reported by one user when attempting to read XQD cards in an off-brand reader which was supposed to read both types. In summary the increased storage and speed of the CF Express type B card is a welcome improvement and works well in compatible devices. It is well worth the money.

I know this review is for the CF Express cards. But, I’ve been a customer of B&H photo since I bought my first brick of Kodachrome 64 from them. So, when it was time to get to memory cards for my new to me Canon 1DX mark iii….. I knew where to go.The cards allow the camera to perform at an insane rate without buffering. I wanted the biggest cards I could get because I don’t want to have to switch cards if I fill one up at a game. I was at a high school volleyball game last week and shot 2038 images and almost filled up a card on my old camera. With this camera and these cards I will never come close to filling them up.Great cards, great customer service and I think I got them at a very reasonable price.
