Delkin Devices Jumps on CFexpress with Latest Release


The next hot media format is finally getting wide release and Delkin Devices is the next manufacturer to jump on board with its own line of CFexpress Memory Cards. This new format will look familiar—the Type-B has an identical form factor to existing XQD, but where it excels is in speed. Using a third-generation PCIe interface and the ability to support NVMe, these CFexpress cards can achieve write speeds of up to 1400 MB/s and read speeds of 1700 MB/s. This makes is a solid choice for newer cinema cameras that record raw video in high frame rates up to 4K or even 5.9K. Photographers shooting continuously in raw can also see a benefit to both write speeds and offload times. 

Delkin backs these cards with a lifetime warranty and they are designed to be shockproof, magnet proof, X-ray proof, anti-static, UV-guarded and temperature resistant. If you encounter any issues, Delkin will replace the card within 48 hours.

You can find these cards in 128GB, 256GB, 512GB, and 1TB sizes.

Are you excited to see some CFexpress cards finally making it out into the wild? Let us know in the Comments section, below!


I think it is better to wait, every day we get something else what is or has to be been changed.

You buy Cfexpress you also need a new cardreader (+/- 50 usdollar).

What if the card fails or does not do what the manufacters have promissed ?

Is it than a problem for customers, maybe Camera factories?

No, the CFexpress card business is at this moment unreliable.

Maybe I see it wrong but I hope not.

Yeah, but do any DSLR cameras use these cards?  Has Nikon developed firmware to support these cards or to replace the XQD cards?  Why not 64GB?

As of the date/time of this reply, there are currently no DSLR cameras that offer native CFexpress memory cards.  However, as CFexpress cards are the same size as XQD memory cards, it is possible to make CFexpress memory cards backwards-compatible with cameras that have XQD card slots with a firmware upgrade.  Nikon has already stated via an earlier press release that they plan to offer a firmware update for the Nikon Z7, Z6, D5 (XQD-type), D850, and Nikon D500 DSLR Cameras in the future to work with CFexpress memory cards.  Also, Canon has stated that the new Canon EOS-1D X Mark III Camera will have dual CFexpress memory card slots.  Once the cards are released, we expect newer high-end DSLR and mirrorless digital cameras to also support the faster CFexpress memory cards.

Yes, Nikon Z6 and Z7 have firmware update for CFexpress 2.20

New tech markup prices are a bit off from reality, because these don't have the licensing issues of XQD. So I'll wait a bit to see how prices settle down before buying. It's great to see cars out that are both faster and more reliable than CF, SD, or XQD.

Having said that, this is extremely excting to see and I will be buying some cards realatively soon.
