SanDisk Extreme PRO Cfexpress Card Type B, 128GB, Up To 1700MB/S, for RAW 4K Video

Absolutely brilliant.

Wouldn't use any other make. Fast, durable and excellent quality

Bit pricey but that’s what you get for a good product.

Fast memory card, works great with my Nikon Z6ii, cand hold a lot of RAW images or vid recording or both. Pricey but you get what you pay for.

I have had several of these and they have never let me down..

Good value but the Extreme Pro name used to mean it was the fastest available now it’s just a name. Having moved from the Extreme Pro SD V90 cards to this I expected it to be top notch performance…but…SanDisk have a card above this called their cinema grade which is the one for higher sustained write rates. The Extreme Pro sustained write speeds top out nowhere near the max number on the card. The net result is for higher FPS cameras you can do RAW bursts, just it will after a short while consume the cards sustained write speed and you’ll be back to waiting for the card to buffer… For me the whole benefit of CFExpress cards is their speed - these are marginally better than SD V90 cards but at higher prices. For the performance there are better cards out there in my opinion.

My husband uses them in a Nikon DLSR camera. Good quality and storage.

If you have a professional camera that has CF Express, for example Nikon or Sony, then this card will give you ample storage, but may not be as quick as stated if the camera was upgraded to use CF Express via software, for example D850. As the card is 512GB then there is a risk of a serious data loss due to corruption but if you have a fast camera with high MP such as D850 or the new Sony Alpha A1 you can be safe in the knowledge you will not run out of space during a days shooting.
