SABRENT CFexpress Type B 512GB Memory Card, Top Speeds of 1700MB/s, PCIe Gen3 Rocket CFX CFexpress Card, for DSLR & 8K Video Cameras (CF-XTBT-512)

I usually use Sandisk for all my cards and SSDs, but these were a great price. They have been working perfectly so far, nice and speedy for my studio shoot and wildlife requirements in a Canon R5. Offload speedily in a standard card reader I also bought from Amazon.

Excellent quality and price. Fast and reliable would certainly buy again

As a professional DP my equipment is vital. My clients rely on me to deliver. This cfexpress card has been excellent so far. It’s allowed me to record RAW with no problems or any overheating. (Using them on my Canon R5’s) It is a well made and well balanced card, not too cheap and not overly expensive. Just right for the working professional like myself who needs many of them. I would recommend this card to anyone.

This works perfectly in my EOS R5 and has huge storage capacity. I chose this brand becuase I've used Sabrent SSDs in my main PC for a few years and they've given me zero issues in this time. I don't shoot video at the moment but I chose a card that is fast enough should I choose to do so in future (at max res and fps). This card was a fraction of the price of some bigger name competitors so represented really good value. Update: almost 2 years on and this card has proven to be perfectly reliable. Worth the money.

On my gh6 this card is perfect and can cope with all the most demanding video codecs, notably the 1,9gbs prores hq and it copes with no issues.

The internet tells me that this is not the card for everyone. I shoot loads of pictures and not much video. I am not a pro so I don't need to worry about missing a shot. This means i can keep my finger on the shutter. I don't really worry about buffers or read and write speeds. This is a good card. I haven't had it long so time will tell if its reliable. I think its worth it

Wow. At the price this is a great buy. I love it and they are the only cards I consider now. Worked fine for over 12 months without a hitch.

For the price, I had no expectations for this card. I wanted to test this shooting 8k prores Flog2. It works great. Read speeds are decent, and the card does not get hot while in the reader. I use this with my MAC studio using a Sandisk reader without any issue. I also use it for my RAW images when not shooting video without issue. The quality of the card is decent, and I don't see it falling apart anytime soon. For the price and capacity it's a no brainer.

Ottima scheda, affidabile, non ha mai dato momenti di incertezza o altro anche lunghe sessioni di ripresa fotografica, velocissima, a 40° di temperatura no problem

The Rocket CFX 1TB CFexpress Type B Memory Card is phenomenal. I use it in my DJI Ronin 4D, and the performance has been flawless. It handles high-bitrate 4K and 6K video recording effortlessly, with zero dropouts or buffering. Playback and file transfers are lightning fast — moving massive RAW files happens in seconds. The build quality feels solid and dependable, with no overheating even after long recording sessions. This card keeps up with demanding production environments and delivers consistent, professional-level performance every time. For filmmakers, photographers, or content creators using the Ronin 4D or similar cinema cameras, this card is a must-have.

Bonnes cartes photos, qualité prix competitif. Je recommande.

The card went well on our trip and didn't miss a beat storing 8k video from a Nikon Z8 camera. Never had an issue.
