It may be due to CFExpress being a relatively new format, trying to impress, but it does seem that the build quality of these next-generation memory cards seems to be excellent across the board. Herewith the Angelbird 256GB CFExpress that quality is instantly apparent with the metal casing and solid build. The robustness of design probably has something to do with the need to keep things cool, but still, after using SD for so long, these things just feel solid. Build quality is good, but it’s those speeds that make this 256GB CFExpress card a must-have for the latest generation of cameras.

What is the Angelbird 256GB CFExpress

The Angelbird 256GB CFexpress features next-generation technology that exceeds the transfer speeds required by most mirrorless and DSLR cameras.

In this review I’m taking a look at the 256GB version, there are more capacity variants in the range which cater for all levels of photographer, from those simply hobbying, right through to photography and video Pros.


As with the SD card format, there are several different types of CFexpress, and the Angelbird card falls into Type-B (AV PRO CFexpress 2.0 Type B), which is the most common for mainstream cameras.

What makes CFexpress so special is the PCIe 3.0 interface technology which provides 1 GB/s data transfer per lane. Type B features two lanes so theoretically you could be looking at 2GB/s transfer speeds which is impressive.

As it is, the Angelbird 256GB CFexpress quotes 1700MB/s read, and 1500MB/s write, that’s more than enough for all compatible cameras on the market at this moment in time.


All cards in the range quote read speeds of up to 1700MB/s and write speeds of 1500MB/s – that’s well beyond the present crop of SD cards.

As these cards are designed to store data from today’s advanced go-anywhere cameras, Angelbird has ensured that their storage technology is equally robust. 


To test out the card out I used a Nikon Z7 and Nikon D850
In the Nikon Z7 and Nikon D850 the card performed without a hitch, it appeared to be as fast as the camera, storing both stills and video as quickly as the camera could record.

Removing the card and downloading the footage and images, the transfer speeds were impressive


The Angelbird 256GB CFexpress and for that matter, all CFexpess card raise an interesting question. They’re all fast, really fast, and at the moment all cards from all manufacturers are of a really good quality, so what differentiates one from another.

The quality is excellent, and the performance impressive.

If you’re in the market for CFexpress, then the Angelbird CFExpress are a great choice.
