SABRENT Rocket CFX 512GB CFexpress Type B Memory Card R1700MB/s W1500MB/s (CF-XTBT-512)

So far, everything works as expected. The advertised capacity is correct, and I'm getting around 350 MB/s in my USB4 CFexpress card reader. The card arrived in a nice metal storage case, which is a nice touch for protection. Shipping took much longer than expected, but that's not the manufacturer's fault. Overall, no complaints about the card itself.

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.

I like Sabrent memory cards. I have a few of them. This was on sale during prime days and it was close to the price it was a year ago. So I grabbed one. Terrific card really cool case and minimal packaging. A++.

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!

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.

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.

SABRENT Rocket CFX 1TB CFexpress Type B Memory Card R1700MB/s W1500MB/s i use this with the canon r3 and it can record 6k raw video perfectly fine. that means it can record the highest data my camera can put out. i also have a sandisk extreme pro 512gb cf express type b card that can record 6k raw video perfectly fine. they both cost the same price and sabrent came with twice the storage; 1tb vs 512gb. the difference is that when i transfer the files from the memory card to the computer the sandisk does it twice as fast as the sabrent; 600mb for the sandisk vs 400mb for the sabrent. therefore, the data transfer rate for the sandisk is faster and can save me more time than the sabrent when transferring files into the computer. i do recommend this product.

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.

Fast transfer speed and no issues at all after a couple of years of usage

Z9で8K動画 （8bit H265）撮影、止まる事なく限界の2時間ちょいまで問題無く撮影、その後も再度同じ条件で撮影。 全く問題なく撮影出来ています。 スチールのRAW撮影も秒20コマで撮影、バッファが詰まっても一瞬指を離すだけですぐに詰まりも解消。 たまたまタイムセールでエンジェルバードAV PRO CFexpress SE 512 GBとほぼ同じ金額で買えたので、コスパ最高でした。 耐久性はまだこれから検証していくところですが、まる二日連続検証の為撮影した感じでは（一杯になったら初期化してすぐに撮影）、現状止まる事は一度もなく順調に記録できています。 ちなみに製造国は台湾です。

Por ahora lo que he probado funciona súper bien. Buenas velocidades, buen acabado y un packaging adecuado. Tendré que probarla mas en profundidad en trabajos de verdad pero por ahora muy contento. ESO SI, al ponerla en el PC con su reader Sabrent no lo reconocía, tuve que meterla en la cámara y a la 2ª por fin me dejo formatearla y ya así el PC la reconoció. Os aviso para que no os de un mini ataque de pánico como a mi.

Z8で使用しています。 読み込みは早いし、安いし、全く問題ありません。 おすすめ。
