The compact design of the Atlas USB4 card reader makes it a travel companion, able to fit into a camera bag. The  aluminum enclosure houses technology like a highly effective new heat sink to prevent thermal throttling and ensure fast, reliable transfers and an Innergize switch enabling users to fully leverage the capabilities of the company’s 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 Larry O’Connor, founder and CEO. “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 card reader is also compatible, supporting both CFexpress 4.0 Type B and 2.0 Type B cards at their maximum speed capabilities. It works with USB 4, 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 – Complete ecosystem for creators
The company has built an assortment of hardware and software solutions to support anyone through the creative process from ‘Capture to Completion’. The 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.

The firm’s Innergize software is an integral part of the ecosystem built for 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.

Atlas USB4 CFexpress Type B memory card reader is available for pre-order and ships in early March for $99.99 on the company webstore. Macsales.com.
