CFexpress Type B 128GB Memory Card - Fast 8K Video Performance

Our review of the CFexpress Type B 128GB memory card finds it best suited for professional photographers and videographers who need sustained high-speed recording and fast transfers. The single biggest reason to buy is its combination of up to 1200 MB/s sustained write performance for 8K capture and up to 1600 MB/s read speed for rapid offload, which noticeably reduces wait time during heavy shoots. For anyone shooting long 8K clips or extended continuous bursts, this card is engineered to keep cameras running without dropped frames or buffer stalls.

Key Features

• 8K Video Support: With up to 1200 MB/s write speed the card sustains ultra-high resolution recording so shooters can capture 8K footage with low latency and fewer dropped frames.
• High-speed Continuous Shooting: Designed to meet demanding burst requirements, it maintains consistent write performance for long sequences of RAW or high-resolution frames.
• Fast File Transfers: The up to 1600 MB/s read speed dramatically shortens offload times so editors can move footage to a workstation and resume shooting sooner.
• Durable Construction: Built from industrial-grade NAND and sealed against magnets, X-rays, UV and static to reduce the risk of accidental data loss during field use.
• Data Security: Factory-tested reliability helps protect valuable images and video files during intensive professional workflows.
• Warranty and Support: A 5-year limited warranty provides added peace of mind for long-term use in professional setups.

Who It's For

This card is aimed at professional and enthusiast photographers, hybrid shooters and videographers who record 8K or high-bitrate 4K footage and rely on sustained write performance and fast download times. Its durability and warranty make it a sensible choice for travel and location work where reliability matters.

Casual users who only capture JPEG photos or short 1080p clips will not fully benefit from the sustained speeds and premium endurance, and may prefer less expensive card formats or capacities if budget is the main concern.
