SanDisk Extreme Pro 256 GB CFexpress Type B 記憶卡 - 讀取 1.66 GB/s - 寫入 1.37 GB/s

Hit 800 fps slow-mo bursts on my A1 without a single buffer stall - this card just keeps writing. The heat sink works better than I expected for sustained 6K recording.

Copying 4K Raw files from my camera to the computer is nearly instant; those quoted 1.66 GB/s read speeds are real. The card feels solidly built, though it does get noticeably warm after a long transfer session.

I’m editing 8K ProRes footage directly off this card and it’s never stuttered—those read speeds make a real difference in my timeline. The build feels sturdy, too, not flimsy like some others I’ve tried.
