Delkin Power Memory Card - CFexpress Type B 4.0 for Digital Cameras | Ideal for Express Transfer of Images and Videos for Storage | Memory Card Storage (512GB)

Great memory card, works well with cameras that demand high throughput for 8k recording.

These are great CFexpress cards, fast and good value until memory prices increased. I use with a Canon R5 camera and can say it handles the speed necessary for 8K video.

Although expensive, I have found this card to be super reliable for long form 4K video up to 120fps and 8K up to 60fps with no issues. Would certainly recommend.

Excellent performance both in camera and with the delkin reader. Just wish they were cheaper (don’t we all).

It’s a very fast card and it was way cheaper when I bought it than it is now, blame AI for the ridiculous price

It is a fast and, so far, reliable memory card. I have noticed that the performance of the camera has significantly improved compared to the previous card. I can take more shots before the buffer starts slowing the camera down. Slightly pricey, but highly recommended anyway.

Happy with the card, decent speed

Excellent value at the price I paid. Very Fast. put 40,000 images through it No issues so far.

I recently moved from a Canon 5DMarkIV to a Canon R5 MarkII and all my old memory was either too small, too slow, or had a know conflict with the new camera(certain SanDisk memory cards have issues with the Canon R5 MII). So I needed some new memory cards and since my new camera has a slot for the newer CF-Express cards I wanted to get one for wildlife and sports photography purposes. The CF Express memory cards are exponentially faster writing than the SDXC cards, allowing the camera to continuously shoot for a longer period before filling the buffer. With a regular SDXC card I would fill up the 70 photo buffer in 1.5 seconds of shooting or less, and then it would take 5 to 15 seconds or more to catch up and write the images to allow more space. This card however allowed me to shoot continuously for much longer, and even when the buffer is reached it quickly writes and refills the buffer to allow more shooting. I can't tell you how amazingly fast this card is, and so far has been very reliable with no issues over the 25 plus soccer and volleyball games I've shot. I was a bit hesitant due to not recognizing the name brand, I've alwasy been a SanDisk guy, but the reviews were good and the price was right so I took a chance on it and I've been extremely happy with the decision. So happy that I bought a second for weekends for when I have a tournament to shoot and need more memory. If you don't need the high speed aspect, such as a portrait or landscape photography, then you could probably just stick to an SDXC card and save some money, but if you need speed for sports, nature, or any other fast paced photography were you need lots of photos in a short period of time, then this is the card to get!

I’ve tested several CFexpress Type B cards with my Canon R5, and the Delkin 1TB stands out. Write and read speeds are blazing fast, handling 8K video and long bursts of RAW stills without any slowdown. What impressed me most compared to other brands is the thermal performance, this card simply doesn’t heat up the way others do, even after extended shoots. Reliability and stability have been excellent. Highly recommended for anyone needing both speed and consistency.

Great quality card. Records at a very good rate. Second Belkin card I have purchased.

Very fast card - I use it in my Nikon z8..There is no overheating when recording in 4k. Fast enough to Croatia, also commendable.

A logical choice for cameras using CFExp B memory cards. Delkin Power cards manage a very good sustained write speed. This gives you a very good buffer, quick start up and good video continuous operation. At a certain size the chip speed of Delkin Power is quicker. It used to be 650Gb or bigger. They no longer sell the 650 in the Power range. The 1Tb is huge. It offers me space for just a few less than 28,000 images on my camera. (HE* compression on a Nikon body.) I buy the Power series. They do have a faster Black series of cards. That is actually only faster if you are testing it in a computer, the extra speed is limited by the camera not the card. These cards don’t have heat issues in my Z9 at all. ( I have Delkin Power 128Gb cards which are also impressively fast for sustained speed. (The 512 Delkin Power not so much.) I continue to HIGHLY RECOMMEND the Delkin Power G4 cards. Their performance is extremely well suited to the currently available cameras.
