CF type A memory card.

[Sudhir Shivaram]

1. CFexpress Type A

   • Why choose it? This is the fastest and most capable card type supported by the A1, ideal for rapid 30 fps bursts and high-bitrate video. It clears the buffer approximately twice as fast as UHS-II SD cards—essential for extended continuous shooting

2. UHS-II SDXC (V60/V90)

   • Why choose it? A more budget-friendly option that still delivers strong performance. UHS-II cards can handle most photo and video tasks—but expect slower buffer clearance (~250 MB/s write speeds) compared to CFexpress (~600 MB/s in-camera) .

   • When it works: For 8K or high‑bitrate formats, UHS-II works (V60 for up to 400 Mbps; V90 for higher rates) but only if not pushing the absolute top limits

3. UHS-I SD Cards

   • Not ideal. These are significantly slower and not recommended unless you’re only shooting stills or low-bitrate video.

• Sony CFexpress Type A M‑Series (960 GB)

  Massive 960 GB capacity, VPG-200 rated, up to 700 MB/s write—perfect for prolonged, intensive shooting.

• Sony CFexpress Type A G‑Series (80 GB)

  Compact and lightning-fast Type A card—great for getting top-tier performance in a more affordable capacity.

• Lexar Professional 2000x UHS‑II SDXC (128 GB)

  High-speed V90 UHS‑II SD card offering excellent performance for photography and 4K video, at a friendlier price.

• SanDisk Extreme PRO UHS‑II SDXC

  A trusted, high-performance V90 SDXC option—reliable and well-supported for everyday pro use.
