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 3,000MB/s write, 3,650MB/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.

Up to 3000MB/s write / up to 3650MB/s read peak performance was observed based on testing OWC Atlas Pro CFexpress cards in an Ableconn PEX-CF106 PCI Express 3.0 x4 Host Adapter Card in a Gigabyte Aorus Master X570 motherboard with an AMD Ryzen 9 5950X 4.9GHz CPU and 32GB RAM, in Windows 10 Pro using Crystal Disk Mark (1GB file size). Sustained write speeds up to 800MB/s were observed. Performance will vary depending on host hardware, software, usage, and Atlas Pro CFexpress card used.
