Specifications
Frequently Asked Questions
What devices are compatible with the SanDisk Extreme PRO CFexpress® Type B card (SDCFE-512G-GN4NN)?
This is a CFexpress® Type B memory card and works only with cameras and devices that specifically support CFexpress Type B. Please check your camera’s manual or manufacturer compatibility list before purchasing.
Is CFexpress Type B the same as XQD or CFexpress Type A?
No. CFexpress Type B uses a different standard than CFexpress Type A, and it is not the same as CF (CompactFlash). Some cameras accept CFexpress Type B in an XQD-shaped slot, but compatibility depends on the camera and firmware—always verify with your camera brand.
What is this card best used for?
CFexpress Type B cards are designed for demanding workflows such as high-resolution burst photography and high-bitrate video recording, where sustained performance and reliability are important.
Should I format the card in my camera or on my computer?
For best results, format the card in your camera (after backing up any files). In-camera formatting helps ensure the file system and settings match what your camera expects.
Do I need a special card reader to transfer files?
Yes. You’ll need a CFexpress® Type B-compatible card reader to transfer files to a computer, unless your camera supports direct transfer via USB. SD or microSD readers will not work.
