OWC Atlas Ultra 1.0TB High-Performance CFexpress 4.0 Type B Memory Card, up to 3650MB/s Read, for Pro Video and Photo

I bought this card with two objectives: offer ample storage space primarily when shooting videos and as a backup unit when traveling. I currently shoot with the Canon R5 mark II and haven’t found any compatibility issues so far. When on the road, I always have a 4TB Thunderbolt 5 external drive with me, but this card is a valid alternative in conjunction with a fast CFExpress Type B card reader.I own several OWC products and I found the always extremely reliable. Very pkeased.

Caught this card on sale. Great speed and no issues. Would definitely recommend.

These cards are easy to use, fast, reliable and the perfect size for most vacations. I did use 2 when we went to Alaska, but there were sooo many photo opportunities from whales to seals to sea lions to glaciers to snow capped mountains… well you get the picture… or I should say… with these cards I got the pictures!

So far, this card has handled everything my R5 could throw at it, including an extended shoot of the eclipse consisting of a whole bunch of large images. Also: Shots of my granddaughter at a recent event in which I decided to see what would happen if it pushed it with some 20FPS shooting and some 4K video: It passed with flying colors.Now, I know the camera, itself, has something to do with it. But I really would have expected to see a lot more buffering, as I have in the past with other camera/card combinations.I also like the construction a lot. With its part metal design, it feels like it's going to be durable. And the way the contacts are protected is thoughtful (though I guess it could accumulate pocket lint, so I have to remember to not toss it unprotected into a pocket).Reading images off this card -- whether by connecting the camera via USB or by inserting the card into an inexpensive reader -- is FAST. I had previously just been shooting with some decent SD cards. My MacBook Pro, after all, has a built in SD card slot. But using SD cards in the slot reader is positively glacial compared to this OWC CFExpress card.All in all, I'm quite satisfied with OWC's card, and expect to remain that way for the foreseeable future.

Picked this up to record 4k 120fps video on my Nikon Z9Works great with no issues or heat.

First time using this kind of card. Way faster transfer speed. Works great for moving a lot of pictures into Lightroom for editing.

Blazing fast! Lives up to the hype.

At first, i was hesitant to buy this 325gb cfe card, but this was on sale for just $108, so i gave it a try. So anyways i will just send it back if doesn’t come up with the promised specs. But then i Try to run it with my R5 with highest burst, and wow it runs w/ an average if up to 190 shots before it starts buffering, 40 shots more than my 128gb sandisk ext pro. Thank you OWC, definitely will recommend this card.
