Over four times faster data transfers compared to USB 3.2 (10Gb/s) memory card readers

Feb 22, 2024 | Woodstock, IL


Other World Computing® – the leading end-to-end ecosystem solution provider of computer hardware, accessories, and software for both consumers and professionals – today introduced the new time redefining Atlas USB4 CFexpress Type B memory card reader at CP+ Camera & Photo Imaging Show in Yokohama, Japan.

Over 4x Faster Ingest vs. USB 3.2 Readers

While conventional USB-C (10Gb/s) readers are fast, users of the Atlas USB4 CFexpress 4.0 Type B Card Reader are in for a transformative experience, witnessing time savings that not only redefine work processes but also freeing up more time for other passions and projects.

The Atlas USB4 CFexpress Type B card reader can slash minutes from transfers, and when paired with OWC Atlas CFA 4.0 memory cards, users can achieve real-world transfer speeds of over 3300MB/s which translates into valuable time savings in managing data and backing it up during, or after, a shoot.

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.
