Integral64GB CFexpress Memory Card Type B 2.0 8K RAW and 4K 120 FPS 1700MB/s Read 1600MB/s Write Speed Designed for the Cinematographer and Professional Photographer

I bought the 256GB Cinematic version of this card and I can confirm it will record 8K RAW video in the Canon EOS R5 camera. Although all CFExpress cards are expensive, this seems a relative bargin compared to other brands that have been confirmed to work with 8K RAW on these cameras.This card has now stopped working in my R5 which locks up when it is inserted and won't format in the camera (hence the change to a single star). Integral customer support is useless. I've been trying to get RMA approval and instructions for weeks and they mostly ignore my emails. I currently have a very expensive piece of junk.

I was concerned that the low price would mean low quality, as the exact read and write speeds are not provided. The card has a metal surround which will help with heat dissipation. So for the speeds, using a MAC and Blackmagic Speed Test the card could write at 600Mbs sustained, and read at 890Mbs Sustained, compare this to the SanDisk which was almost double the cost the speeds for that card were 700Mbs Write Sustained and 900Mbs Read sustained. These results make the Integral CFx Card an absolute bargain, couple that with a 5yr Warranty its superb value for money.

Will not work with the Canon EOS R5 in all 8k modes and 4k 120fps. Shame.

I bought this card and card reader to use with the Nikon Z6ii and overall I've been left frustrated by its results (at the moment). I've had no issues with the Integral card in my Z6II body. I've taken loads of pictures, a few short videos, and it's worked perfectly.So why the 2 stars? Well I bought Integral's card reader to speed up my image transfers. When it comes to using Integral's own CFexpress card in Integral's own card reader on a Windows PC (with the latest Windows 10 updates applied for good measure) you'll be able to view images/ videos and transfer images from card to computer for 1 to 2 minutes before the card reader will lock up. Now if you thought the issue was with a dodgy card reader, Integral was kind enough to provide me with another card reader, and the same problems occurred. I even bought the ProGrade Digital card reader, and saw the same problems arise. ProGrade Digital's card reader comes with an SD card reader too, so I tested that with the SD card in my Z6 II and it worked flawlessly.Oh and I got a replacement Integral CFexpress card from Amazon, and I'm still not able to use a card reader to transfer files from card to computer without the use of my camera body.So I don't know what else to do now. I've registered this problem with Integral and with ProGrade Digital on their respective websites and so will report back here when I've received more responses. In the meantime if anyone who comes across this review has any idea how to get the card to work in a card reader, I'm all ears and would very much appreciate the help!Otherwise I'm thinking of sending card and card reader back, as they're just too expensive not to work properly.It's worth noting that on Nikon's website they do not list Integral as an officially supported card, but frustratingly it's also worth noting that I seem to be the only one having this issue as no one else online that I can find has talked about it.

As of 3rd December Nikon have been offering a firmware update (v1.30) for the D500 to allow the use of CFExpress cards in XQD card slot. Go to the Nikon site for your territory and head to the support pages, then D500 sub pages / firmware updates. The latest previous version was 1.20, but you may be on versions earlier than this (1.1.X). Download the latest version, open the file on your computer and then extract the .bin file and transfer this file to the main root directory on a memory card that has been formatted in the Nikon camera you are updating.With well charged Nikon batteries inserted go to the settings menus and head to the firmware update menu, select to update, then click OK. It takes about 2-3 minutes on a Sandisk U3 SDXC card. Once updated switch the camera off/on, and bingo the CFExpress card works. My card contained a warning saying trying to use it in a non updated camera could corrupt the card, so be warned. I’ve not tested it for speed or video duties yet, but the buffer doesn’t appear to be slowing down which is encouraging. Once I’ve used the card in the field I will post an update of usable performance.
