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 Ultra CFexpress cards for reliable peak performance up to 1500MB/s write, 1700MB/s read, and 1300MB/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.
After intensive stress tests with multiple full capacity cycles, the Atlas FXR reader still delivers consistent sustained 1400MB/s read and 1200MB/s write performance from a 650GB Atlas Ultra CFexpress card while maintaining a safe temperature.
