The Nikon Z6 III is a 24.5 MP full-frame mirrorless camera that features two memory card slots.
One slot supports the extremely fast CFexpress Type B cards or the older XQD cards, and the other slot supports SD/SDHC/SDXC (UHS-II / UHS-I) cards.
The CFexpress 2.0 standard is supported but not the latest 4.0 standard. CFexpress 4.0 cards can still be used but you won't see any speed benefits in-camera, only when copying images to your computer with a 4.0 reader.
If you want to record video in 6K RAW (6048×3402) at 60p (3730 Mbps) then you will need a CFexpress Type B card that supports a minimum sustained write speed of 467 MB/s. We would recommend a card that is VPG400 certified.

FAQs
How many images can be stored on a 512GB card?
The number of images that can be stored on a 512GB memory card in the Nikon Z6 III varies based on the image type that you are recording in. The following values are approximate because file size varies with the scene being shot:
- NEF (RAW), lossless compression: 18,700
- NEF (RAW), high efficiency *: 29,500
- NEF (RAW), high efficiency: 44,900
- JPEG/HEIF fine/large: 49,700
- JPEG/HEIF normal/large: 81,200
How many minutes of 6048×3402; 60p video can be recorded on a 512GB card in the Z6 III?
When recording in 6048×3402; 60p (3730 Mbps) you can record approximately 18 minutes of video on a 512GB card.
Are CFexpress Type B 4.0 cards compatible with the Nikon Z6 III?
Yes, the Nikon Z6 III is compatible with CFexpress 4.0 cards because the 4.0 standard is backward compatible with 2.0. Unfortunately in-camera there is no speed benefit to using a 4.0 card over a 2.0 card because the Z6 III memory bus does not support the faster 4.0 speeds. Where you will see a benefit is when copying files from your memory card to your computer, with a 4.0 card this can be up to twice as fast compared to a 2.0 card when using a CFexpress 4.0 Type B compatible reader.
What is the difference between CFexpress Type B 2.0 and 4.0?
The main difference is speed. CFexpress Type B 4.0 cards utilize the PCIe Gen 4 bus which delivers twice the bandwidth (up to 4 GB/s) compared to CFexpress 2.0 Type B cards that utilize the PCIe Gen 3 bus (up to 2 GB/s).
CFexpress Type B 4.0 cards are backward compatible with CFexpress 2.0 devices, meaning a 4.0 card will work in a 2.0 camera or reader, but the performance will be limited to CFexpress 2.0 speeds. Similarly, a CFexpress 2.0 card will perform at its peak in a CFexpress 4.0 device.
Are CFexpress Type A cards compatible with the Nikon Z6 III?
No. The Nikon Z6 III is not compatible with the physically smaller CFexpress Type A cards.
Where can you find the Nikon Z6 III specifications?
Full specifications for the Nikon Z6 III can be found on Nikon's website.
