Truth in Numbers
Big theoretical performance numbers are certainly eye-catchers, but they are misleading when your workflow requires real-world speed. That’s why we take the extra time to run OWC flash storage solutions through intensive performance testing, and we share our test setup and parameters. Truthfully listing Atlas Pro CFexpress cards for reliable peak performance up to 1500MB/s write, 1700MB/s read, and up to 400MB/s sustained write speed defines our commitment to the “OWC Difference,” which ensures these CFexpress Type B cards will deliver the performance you are counting on.


Get Maximum Performance from Your Atlas Ultra CFexpress Cards
Details matter when it comes to obtaining the highest performance from your CFexpress card. Only use a high-quality CFexpress Type B memory card reader such as the OWC Atlas FXR that has been specifically designed and extensively test proven to deliver effective heat dissipation so your memory card will deliver maximum sustained throttle-free performance.

If you must use a camera or reader that doesn’t dissipate heat effectively, Atlas Ultra CFexpress cards have built-in protection that automatically reduces speed to prevent heat damage while ensuring a safe to handle temperature.
