BMCC 6K has one memory card slot, supports CFexpress Type B memory cards. We have tested and reviewed late CFexpress Type B cards, and below are top recommended ones for Blackmagic Design Cinema Camera 6K:

For the absolute fastest speeds, the Lexar Professional CFexpress Type-B DIAMOND is my top pick. With blazing read/write speeds up to 1,900/1,700 MB/s, it can easily handle the data rate demands of 6K RAW recording. Lexar is a proven brand and this card has excellent performance. Downsides are its premium price and lack of VPG rating for sustained write speeds.

The Sony Tough CFexpress Type-B offers a great balance of speed, toughness, and value. With speeds up to 1,850/1,750 MB/s read/write, it provides ample performance for the camera’s needs. And with Sony’s reputation for reliability plus a durable, shockproof design, this card should keep working despite the rigors of video production. The price is also more affordable than other top-tier CFexpress cards.

For those on a budget, the Wise Advanced CFX-B provides decent 6K RAW recording speeds of 1,700/1,550 MB/s at a lower price point. The main tradeoff is consistency – sustained write speeds may drop lower during long takes. But for the price, it’s a viable option.

Ultimately, my top recommendation is the Sony Tough CFexpress Type-B. It delivers excellent, consistent performance for 6K RAW video on the Blackmagic Cinema Camera 6K at a reasonable price from a reliable brand. For no-compromise speeds, step up to the Lexar DIAMOND. And for a lower-cost alternative, check out the Wise Advanced card. But for most users, the Sony strikes the optimal balance of speed, toughness, value and reliability.
