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 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.
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 2TB Atlas Ultra CFexpress card while maintaining a safe temperature.
Innergize Your Workflow with Highest Performance and Reliability
OWC Innergize™ is the first stage of the Capture to Completion™ ecosystem of OWC products designed to seamlessly propel professional photographers, videographers, and content creators to the highest level of workflow performance and reliability. This OWC custom-designed app is a complete health, performance, and field upgrade management tool when using OWC Atlas memory cards with OWC Atlas readers and reader equipped products.
Work with Maximum Confidence and Reliability
Health
Over time and use cycles, flash memory does wear out. Innergize verifies and reports the percentage of use life remaining. Now you can work with full confidence your OWC flash memory product will deliver the reliability you can trust.
Sanitize
Writes, deletes, and formatting all take their toll on memory cards. Innergize cleans and restores the flash memory performance of OWC memory cards so you can get the best results on every use.
Field Upgrade
When new cameras or firmware updates to existing cameras are introduced, they may not work properly with flash memory cards and drives. 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.
