The compact design of the Atlas USB4 card reader makes it an ideal travel companion, able to seamlessly fit into any camera bag. The sturdy aluminum enclosure houses cutting-edge technology like a highly effective new heat sink to prevent thermal throttling and ensure fast, reliable transfers and an innovative Innergize switch enabling users to fully leverage the capabilities of OWC Innergize software while it can boost USB 3.2 transfer rates by over 30% compared to previous generation of USB 3.2 products.

"Our Atlas series of professional photography and videographer tools continue to break down barriers and address challenges creative professionals face, namely, critical time savings," said OWC Founder and CEO Larry O'Connor. "We have implemented a unique switch that will allow this reader to interface with various computers and in all instances still allow the user to benefit from the OWC Innergize software."

The Atlas USB4 CFexpress card reader is also extremely compatible, supporting both CFexpress 4.0 Type B and 2.0 Type B cards at their maximum speed capabilities. It seamlessly works with USB4, USB 3, and Thunderbolt 4 and 3 on Mac, Windows, and Linux computers. Additionally, it is designed to work with iPads, iPhones, and Chromebooks.

Atlas - A Complete Ecosystem for Creators

OWC has built the most comprehensive assortment of hardware and software solutions to support anyone through the creative process from Capture to Completion™. The OWC Atlas ecosystem is the first step of the process to ensure photographers/videographers have the tools they need to get their vision from camera to audience.

OWC's Innergize™ software is an integral part of the ecosystem built for OWC Atlas memory cards and readers. Innergize first checks the health of an Atlas card to ensure it is reliable to use, and then cleans and restores performance so there will be zero dropped frames when shooting video or continuous burst photos. Atlas owners can then upgrade their firmware in the field to take advantage of the latest card improvements and ensure OWC cards and readers will perform optimally with their cameras.
