SABRENT Rocket CFX 512GB CFexpress Type B Memory Card (CF-XTBT-512)

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.

Such a good card I got a second. Has done great work with my Canon R5 and even does fine at 120fps

Stable and fast cards. Really great choice for photography.

The Sabrent CFexpress card is amazingly fast in my mirrorless camera. My camera has a slot for a SD card and a CF type B. When shooting with the memory card it will start buffering while I'm hammering out photos or video. When it switches to the Sargent I can instantly tell because the buffering stops. I got a 512 gb and it's been plenty of space for my shooting. The card is well made and the case is amazingly well built. It works in my Fuji X H2 and in my Black Magic with no compatability issues. Overall it was a great buy. Con: the only downside it has is that it doesn't come with a reader. I had to purchase that separately.

An amazing product, very fast and reliable.

The foam lined storage case it comes in looks pretty solid, but card can get stuck and can't be removed with your fingers. If you use a screw driver to pry it out be careful not to damage the card. 512 GB: Good card. My wife and I bought 6 for our Z9s. Recorded and uploaded thousands of photos and video with no problems. 1TB seems to have a Z9 compatibility problem: After recording a day's worth of photos on both Z9s we transferred files to SSDs using our laptop. When we reinstalled the cards, the cameras couldn't read them any more.

Much cheaper than most of the certified CFX type B cards on the market and has worked great for me in my camera. I haven't had any issues with speed or lost images since i bought it. That said if you are doing work where a single lost shot can be devastating maybe go with the ones your camera manufacturer officially recommends. For hobbyist photographers and videographers these are great!

I owned Nikon D850 and Z6, both could take XQD. A few years back, it was only Sony who manufactured quality XQD, it priced expensive. Paired with Sony XQD reader, it never reached read speed 400MB/s per its spec. Now with this SABRENT Rocket CFX 512GB, paired with its CFexpress Type B Memory Card reader, it reached read speed 1.65 GB/s, write speed 1.45GB with provided USB-C cable. My PC system memory is Silicon Power 1TB NVMe M.2 PCIe Gen3x4 2280 TLC R/W up to 3,400/3,000MB/s SSD. Upgraded D850 and Z6 to its latest firmware version, both of them took SABRENT Rocket CFX 512GB at ease. On Nikon D850, its speed is on par with Sony XQD 120GB 440 GB/s Rd 400 GB/s WR. On Nikon Z6, its speed is 25% faster than Sony XQD 120GB 440 MB/s Rd 400 MB/s. I'm guessing my aged Nikon models might have not been able to fully utilize this card speed. I'm confident it will be super faster on Nikon Z9. I'm totally satisfied with its performance Sabrent CFexpress Type B 512GB card for now. It looks extremely solid build. I'll take it to my incoming vacation abroad.
