Benchmark Speed Tests: Read and Write Performance

Using a high-end CFexpress 4.0 reader and a Thunderbolt 4 port, we ran CrystalDiskMark to measure sequential and random speeds. The Capture+ CFexpress Type B 4.0 delivered impressive sequential read speeds of up to 3,400 MB/s and write speeds of up to 2,900 MB/s. These numbers place it among the fastest CFexpress cards available, rivaling even the most expensive options.

Random read/write speeds, which are critical for small file transfers like thumbnail previews, were equally strong. The card handled 4K random reads at over 100 MB/s, ensuring smooth browsing through thousands of photos in post-production. These benchmark results confirm that the Capture+ CFexpress Type B 4.0 is built for speed, but real-world performance is where it truly matters.

• Sequential read: 3,400 MB/s
• Sequential write: 2,900 MB/s
• Sustained performance without thermal throttling

Real-World Performance: Photography and Video

In a real-world test with a Canon EOS R5, we shot continuous bursts in RAW+JPEG mode at 20 fps. The Capture+ CFexpress Type B 4.0 never hit a buffer limit, allowing us to capture over 1,000 frames without a pause. The card's write speeds ensured that the camera's buffer cleared almost instantly, making it ideal for sports and wildlife photographers who need to capture fleeting moments.

For videographers, the card handled 8K RAW recording at 30 fps with ease, as well as 4K at 120 fps in 10-bit. We recorded over 30 minutes of continuous 8K footage without any dropped frames or overheating issues. The card's heat dissipation kept temperatures stable, even during long recording sessions in warm conditions. This level of reliability is essential for professional shoots where there's no room for error.

• No buffer limits in continuous shooting
• Smooth 8K RAW and 4K 120fps recording
• Stable performance in warm environments

Durability and Reliability

Professional storage must withstand the rigors of travel and frequent use. The Capture+ CFexpress Type B 4.0 is rated for extreme temperatures, shock, and vibration, making it a reliable companion for outdoor shoots. We accidentally dropped the card from waist height onto a concrete floor, and it continued to work flawlessly—a testament to its robust construction.

In terms of longevity, CFexpress cards are designed for high endurance, and the Capture+ card is no exception. It uses high-quality NAND flash that supports thousands of write cycles, ensuring years of reliable use. For professionals who depend on their gear, this reliability is as important as speed.
