High power efficiency and endurance provided by top-grade hardware. Dual PCIe 3.0 lanes to reach speeds of up to 1,800 MB/s for reads and 1,700 MB/s for writes to give you the fastest transfer rates possible. Sustained writes with the potential of up to 750 MB/s at 512GB, offer enough speed for any type of HD recording. IOPs of up to over 300,000 allow quick access to all of your photos and files. SSD-grade hardware for both the controller and the flash memory. High endurance thanks to quality hardware and powerful wear management features such as LDPC, ECC RAID, end-to-end data protection, SmartRefresh, wear-leveling, plus support for TRIM.

I will preface this review in saying that I have used Sabrent drives in computers for a number of years now, and fortunately I have had no issues with any of them.When I first saw these Sabrent CFexpress cards, I initially passed them up, because the non-pro ones don't have the sustained write speeds of the higher end cards. However when these pro versions were released I became very curious. I couldn't find many real world reviews, and honestly the wording of up to, potentially 1300 MB/s was a bit concerning. Of the reviews I did find I wasn't sure if they tested the sustained write metric or not, and to me that is the most important metric to test in a large capacity card like this. I ended up taking the chance and getting this card, and I'm glad that I ...

I ended up taking the chance and getting this card, and I'm glad that I did.This easily keeps within the sustained minimum write speeds, and has not given me any issues with 8k30 or 4k120 fps on the Nikon Z8. Didn't try 8k60, but from what I've seen just by writing a terabyte of files to the card all at once in Windows as a test, that shouldn't be an issue. It was between 1500 and 1300 the entire time.Other than that, what else is there to say? It is a fast CFexpress card that's much cheaper than some other options, that's from a reliable SSD company. It's overkill for capturing stills on my Z8. I'm very glad Sabrent entered the pro camera market space, and I hope the competition brings some of the crazy prices down among the high-end cards. I highly recommend this card.

As I'm starting to shoot more N-Raw video on my Nikon Z9 I needed (a lot) more storage than my current 325GB Delkin Black. I noticed this new 2TB Rocket Pro CFExpress B from Sabrent was available at a more reasonable price that most of the competition. Sabrent technical support confirmed this new card is designed to support continuous writes of 1300 GB/s and is only limited by the device, so I picked one up and my initial tests confirmed that the card supports all video recording modes in a Z9 up to and including NRaw 8.3k 60p in high quality (which generates the highest bit rates) for at least 10 minutes. I also tested 4.1k120p, 5k60pDX and 4k120p DX in N-Raw without issue. The card does get hot during long recording times, which is common. Download speeds using a ...

Download speeds using a Delkin CFExpress reader averages about 400MB/s to my Mac Studio, or about 10% FASTER than my Delkin Black card. I have no hesitation recommending this card for the Z9.

The packaging is great, the little aluminum clamshell case that the card comes in works great as a storage case, and is held closed magnetically. USB speed tests confirmed the specs that this card is rated at, but inside both of my z6ii and z7ii cameras, it was barely faster than the 128gb v90 PNY SD cards. I tried it with the SD installed, running as an overflow card, and also the Sabrent running solo in both cameras. Both at max resolution, a combination of JPG, RAW, and JPG+RAW. In the z6ii the fastest write speed I calculated was 203mb/sec. The z7ii hit 195. The 128gb PNY V90 SD cards in both cameras averaged 185-190mb/sec, which impressed me. I'm not sure if it is a firmware issue in the card or what, but for the price I would expect a lot more speed out of the ...

This card is woking fine on my Canon R5C, recording at 8k60fps LT at 2570mbs for 30 minutes with no issue.Transfer speed using theSabrent CFexpress Type-B Thunderbolt 3 Card Readerwith 100GB file was 1:01min(Read) to MacBook Pro M2 and 1:12min(Write) to transfer the other way around. Make sure to use the USB C cable supplied with the card reader or equivalent high quality cable, since when using an ordinary USB C cable the transfer speed was poor.
