SABRENT Rocket CFX PRO 512GB CFexpress Type B Memory Card R1800MB/s W1700MB/s [CF-XXIT-512]

Fast and cool. Value for money.

Works with R3D NE on Nikon ZR at 6k60. I know this is not on the recommended list from Nikon but it still works and at this price, it's hard to pass up. I bought the 2TB for $400 in mid-2026. If you know what has happened with memory prices, you know that this is a great deal. I am not shooting hour long videos at max bit rates but for my use, it's working flawlessly.

I'm seriously impressed. I wanted to test the limits, not like I'd use this in production... Nikon Z8 @ 8.3K RAW (N-RAW), full frame (FX), 60p, on HIGH quality, not NORMAL, which is absolutely not needed in any scenario I can possibly think of, and this card had ZERO ISSUES! How? 2TB for $399? Obviously I'd need to run long term tests here but if it can do this, I don't think it'll have any issues whatsoever with 8K 24p on Normal.

Handles 8K60p RAW on my Canon R5C with no issues. Why it's half the price if comparable cards makes no sense to me.

First, gripe is the packaging. Come on, there could have been a hundred of these in the box it was shipped in. The package itself is streamlined and minimal, but the box it was shipped in? Anyway, the card itself is awesome. The aluminum container is terrific. The card appears to be well built. I formares it in camera which took less than 2 seconds, then I fired off at 120 frames a second 400 or so images. Zero lag. Zero buffer. It was just hungry for more. Terrific. I then ingested those images into my computer and it flew. Then I deleted the images and reformatted it. It is way faster than any other memory card I own. I took a pic of a few. Terrific Excited.

I only recently received two of these cards, and I am using them in my recently purchased Z8. (The camera and cards arrived on the same day.) So far, they are doing what is expected of them with no issues. I cannot say that they are faster or slower than any other cards, as they are the only CFexpress cards that I now own. I got them because they seemed to be in the middle of the high-end and low-end cards in terms of price, and for the speed, well, it works, and I have not noticed any delays in writing data to the card that is limiting the camera, so I am happy with them. They are well packaged and look and feel very premium.

I wanted the largest, fastest, reliable storage for my R5C. This is it. Combined with a tbunderbolt card reader, I can edit 8k raw directly from the card, which is much easier than transferring to my computer. This card supports every flavor of recording options on the R5C. I’ve had no overheat issues, the card has not failed, and the speed seems consistent, mitigating against dropped frames. Using BMD speed test with my thunderbolt reader, I can confirm the card has approximately 1500 MB/s sustained write, and 1700 MB/s sustained read. Overkill I’m sure for current recording options in cameras, but that will probably change in a year or two. The card is very expensive, but I think it’s worth the investment if you intend on using fast bitrate cameras in the future.

This was my first time purchasing a CFX card as I’d just gotten the R5. After shooting a few hours total of 4K high frame rate video, I can say that the card keeps up with the camera and I’ve had no issues with overheating. I also bought a Sabrent card reader and it transfers very quickly. Overall, I’m glad I purchased this card over the V1 card and certainly more than other brand cards that are twice as much.

Molto buono velocissimo nessun problema

Simple order process and Amazon keeps you informed of delivery progress. Product was a good price for a quality product.

I bought this card to pair it with my Canon R5C and it works perfectly in any recording format, even 8K, and any frame rate. No limitations. If you're looking for a card that allows you to record 8K, 6K or 4K, this is the best option.

Después de varios meses de uso intenso profesional (cientos de miles de fotos), puedo decir que es una muy buena compra.

I got this to shoot at the highest possible quality on the Nikon Z8 and looked at all the usual suspects. For storage vs cost this is incredible value and extremely fast. I've tested this on my Nikon Raw 8k and Pro-res HQ and there's no problem at all and no overheating. Just to make double sure before a film shoot, I left it recording until the battery ran out on my Z8 and it still wasn't full, I guess shooting 8K eats batteries. I already own several Sabrent 8TB NVME in my Raid drive, so don't have any problems with their reliability. Comes with a handy metal copper looking case with foam inserts. Not so long ago 1TB was something beyond reach due to exorbitant costs, very happy with the purchase. Highly recommended!
