The OWC Atlas CFexpress Card Reader is an ultra-fast, compact USB4 (40 Gb/s) CFexpress 4.0 Type B card reader designed for creative professionals who need high-speed ingestion for CFexpress Type B and Type A cards (Type A via included adapter). It connects via a USB-C interface and is compatible with a wide range of devices including USB4, Thunderbolt 4, and USB-C equipped Macs, Windows PCs, iPads, Chromebooks, tablets, and smartphones. The reader is bus-powered, pocket-sized, and built with a heat sink and heat-resistant components to reduce thermal throttling and maintain sustained performance.

Advantages

The device is designed for portability, stability with non-skid rubber feet, and secure cable connection options. It also integrates with OWC Innergize software for card health monitoring, sanitization, and field firmware upgrades.

How to use

Connect the reader to your computer or mobile device using the included USB-C cable. Insert a CFexpress Type B card directly or use the supplied Type A to Type B adapter for CFexpress Type A cards. The reader automatically detects the connection speed and provides status feedback via the integrated LED. Use your operating system’s file manager or preferred ingestion software to copy files from the card to your drive. For best sustained performance, ensure adequate ventilation around the reader to allow its heat sink to dissipate heat.

Recommendations

Use OWC Atlas memory cards with the Innergize app to monitor card health, perform sanitation routines, and apply field firmware upgrades for maximum compatibility and reliability. Keep the reader on a stable surface and consider an OWC ClingOn cable stabilizer (sold separately) to prevent accidental disconnection during critical transfers.
