Yes, the Nikon Z8 is compatible with the Samsung PRO Plus 256GB SD.
Nikon Z8 Slot 2 accepts UHS-I SD cards. Samsung Pro Plus is UHS-I V30 (~90 MB/s) -- meets the Z8 minimum for basic video recording (UHS Speed Class 3 required) and still photography. Cannot record video at high frame size or rate, which requires a minimum 250 MB/s SD card per Nikon specification.
Conditions for compatibility
Compatible for still photography and basic H.265/H.264 video recording (UHS Speed Class 3 met). Cannot record video at high frame size or rate (requires 250 MB/s — Samsung Pro Plus at 130 MB/s UHS-I V30 does not qualify). N-RAW and ProRes RAW HQ are CFexpress Type B only. Not recommended for demanding video workflows.
“The camera can be used with CFexpress (Type B), XQD, SD, SDHC, and SDXC memory cards.”
