What fits in each slot
| Slot | Formats | Interface | Workflow note |
|---|---|---|---|
| Slot 1 | CFexpress Type B or XQD | CFexpress / XQD | Supports high-speed still and RAW video media. |
| Slot 2 | CFexpress Type B or XQD | CFexpress / XQD | Same physical format support as Slot 1. |
When faster media matters
A Nikon-approved CFexpress Type B card; 45 MB/s maximum-transfer-rate guidance covers ordinary video playback and recording.
A listed Type B card with at least 250 MB/s maximum transfer, preferably a Nikon-recommended VPG400 model for N-RAW or ProRes RAW HQ.
Nikon specifically recommends select Type B card families for N-RAW 12-bit and ProRes RAW HQ 12-bit recording.
Plan the complete workflow
Capacity
The camera supports CFexpress Type B and XQD. Match both card type and performance for redundant high-rate work.
Reader
Use a Type B/XQD-compatible reader and confirm that it supports the exact standard of the inserted card.
Three checks worth making
- The Z9 does not use SD cards.
- XQD and Type B share a slot but are different standards.
- RAW video should use a specifically approved card model.
Verify the current requirement
