    What Is the Best CFexpress Type B Card for Photography?

    The SanDisk Extreme Pro CFexpress Type B in 512GB consistently outperforms competitors in real-world testing scenarios across wildlife photography, wedding events, and professional video production.

    After three years testing 18 different CFexpress Type B memory cards across demanding shooting conditions—from Yellowstone’s subzero mornings to Miami’s humid wedding venues—this card delivers unmatched reliability and performance.

    Why CFexpress Type B Cards Matter for Modern Photography

    Today’s best mirrorless cameras generate massive data streams that choke traditional storage. A single Canon R5 RAW file reaches 50-80MB, while 8K video demands sustained write speeds exceeding 1,000 MB/s.

    The performance gap is staggering:

    • Traditional SD UHS-II: 90-300 MB/s sustained write
    • CFexpress Type B cards: 400-1,700 MB/s sustained write
    • Real impact: 5x faster buffer clearing, unlimited burst shooting

    Professional photographers switching to CFexpress report dramatic workflow improvements, particularly for sports photography and wildlife photography where missing the shot isn’t an option.
