ProGrade Digital Memory Card - CFexpress 4.0 Type B for Cameras | Optimized for Express Transfer of Files & Large Storage | 512GB Gold Series

Outstanding 1TB memory card.I also purchased the ProGrade card reader, this alowed me to verify it was a genuine card with the ProGrade app and upgrade the card firmware all in one go.Any buffering with other memory cards has disapeared.Superb frame rate without buffering for winldlife and sports.Very happy with this purchase.

Lightning fast card! Used in fujifilm x-h2s camera to shoot motor racing. Didn't miss a single shot. Price wise I think this is very good value for money. Would i buy again, definitely yes. Recommended.

Excellent value for money and works very well in my Nikon Z8, 3-4s before buffer full at full FX compressed, unlimited at DX size. Even when buffer fills camera still takes photos but a slightly reduced speed. 6,000 pics at FX compressed, 13,000 at DX, so plenty even at 20fps. Guarantee not as good as say Delkin Black, but at half the price for a bigger size worth it in my view.So good I bought another one.

Bought on Black Friday at a much reduced price. Excellent quality from a good manufacturer. Works well in my cameras

Excellent memory card, with good read and write speeds. Nice that it comes in minimal packaging too.

I’m using this card with the Nikon’s Z8 camera. If you are happy to use the camera in the compressed raw HE* mode rather than uncompressed raw then I fully recommend this card. For videographer, all of Nikons video codecs work with this card. In addition, if used with a version 4.0 card reader and thunderbolt equipped computer, you will get the benefits of faster upload transfer rates.When capturing uncompressed raw images in burst mode this card captures about 70 images at 20 fps before the image buffer fills. At that point it continues to record at about 10fps until the card is full. Using the compressed raw HE* mode one can capture an over 200 images before the buffer fills. Once the buffer is filled and shooting stops it is cleared pretty quickly allowing one to shoot at full speed again.This card is a version 4.0 card but there are currently no cameras that support this specification. The card does work in current cameras but at half the specified speed. This card is advertised with a read speed of 3400MB/S and a sustained wite speed of 2400MB/S leading one to believe images can be captured at full speed and without buffering issues. What’s more confusing is that the label on the card indicates a sustained write speed of 850MB/S which is at the bottom end of acceptability. ProGrade’s web site indicates that they have changed their benchmark algorithms and as a result have changed the sustained write speeds. These new figures are misleading and are out of line with the rest of the industry making it difficult for consumers to compare products on a like for like basis.

A high performance card, perfect for my new GH7. Write speed is very fast, however read speed is a bit lower than I expected, possibly due to the reader I'm using.

Have three of these cards now. Use them with my R5 for photo and film. They are reliable and fast and cheap in comparison to other brands.
