CFexpress Type B cards are the fast media used in many high-end stills and video cameras. Speed figures, capacity and the card generation (2.0 or 4.0) all matter, and the right choice depends on what your camera supports. Check your camera’s manual before buying.
The six cards below span 128 GB to 1920 GB and both generations. Speeds, sizes and build notes come from each product’s listing page. We have not used these cards ourselves. All speed and durability figures are the makers’ own, and a camera may not reach the maximum.

| Generation | 4.0 cards are faster, but your camera must support them |
| Capacity | High-resolution video fills cards quickly |
| Build | Bend, drop and temperature claims are the maker’s |
| Card reader | A matching reader helps when copying files |
