Truth in Numbers

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 3000MB/s write, 3650MB/s read, and up to 800MB/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
