The Nikon Z8 is a 45.7 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.
If you want to record video in N-RAW 12-bit 8256×4644 : 60p (5780 Mbps) we would recommend a CFexpress Type B card with a minimum sustained write speed of 1000 MB/s, although you might get away with 850 MB/s.

FAQs
How many images can be stored on a 325GB card?
The number of images that can be stored on a 325GB memory card in the Nikon Z8 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: 3600
- NEF (RAW), high efficiency *: 8500
- NEF (RAW), high efficiency: 12,100
- JPEG/HEIF fine/large: 10,400
- JPEG/HEIF normal/large: 20,600
How many minutes of N-RAW video can be recorded on a 325GB card?
When recording in N-RAW 12-bit 8256×4644 : 60p (5780 Mbps) you can record approximately 7 minutes of video on a 325GB card.
Are CFexpress Type B 4.0 cards compatible with the Nikon Z8?
Yes, the Nikon Z8 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 Z8 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 Z8?
No. The Nikon Z8 is not compatible with the physically smaller CFexpress Type A cards.
Where can you find the Nikon Z8 specifications?
Full specifications for the Nikon Z8 can be found on Nikon's website.
