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 Ultra CFexpress cards for reliable peak performance up to 3000MB/s write, 3650MB/s read, and up to 1500MB/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.
Maximum Sequential and Sustained Read/Write Performances delivered by OWC’s Atlas Ultra CFexpress 4.0 Cards
Details matter when it comes to making an investment into a memory card for your camera. That is why OWC Atlas Ultra CFexpress 4.0 cards leverage the CFA 4.0 specification that is backward compatible with CFA 2.0 (i.e. PCIe Gen3) cameras and readers of today; and forward compatible with CFA 4.0(i.e. PCIe Gen4) cameras and readers of the future delivering the highest performance that you deserve.
Over 3700MB/s and 3100MB/s sequential read and write and 3300MB/s and 1500MB/s sustained read and write performance from a 1TB Atlas Ultra CFexpress 4.0 card measured on a Windows 11 computer with AMD Ryzen 9 processor mounted on a Gigabyte Technology x570 Aorus Master motherboard with 32GB of RAM.

Innergize gives OWC memory card users the ability to quickly upgrade their firmware in the field for full compatibility, additional performance enhancements, and bug fixes for optimal reliability.
- Up to 3000MB/s write / up to 3650MB/s read peak performance was observed based on testing OWC Atlas Ultra CFexpress cards in an Ableconn PEX-CF106 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 1500MB/s were observed. Performance will vary depending on host hardware, software, usage, and Atlas Ultra CFexpress card used.
