Who is it for?
What is it for?
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 1700MB/s write, 1850MB/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.
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 Pro 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.
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.
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.
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.
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.
