OWC Atlas Dual SDXC UHS-II Card Reader USB 3.0 Space Gray

Dual-Slot SDXC UHS-II Reader

The OWC Atlas Dual SDXC UHS-II Card Reader is an external, bus-powered device built for professional photographers, filmmakers, DITs, and content creators who need to ingest from two cards at once. It connects via USB 3.0 and works with Mac, Windows, iPad, and Chrome OS. The compact Space Gray enclosure is pocket-sized for travel and includes non-skid feet plus a cable management feature to keep the unit stable on a desk.

Thermals, Noise and Power Draw

As a bus-powered reader with no moving parts, it draws power directly from the host USB-C port and runs silently. The aluminium chassis passively dissipates any heat generated during sustained transfers, so there is no fan noise or external power brick to manage. Typical operation stays within the USB 3.0 power budget without requiring a separate supply.

Bundled Accessories and Software Impact

The integrated USB-C cable tucks away when not in use, and a second USB-C port allows a longer cable for studio setups while retaining built-in port protection. A hardware write-protection switch applies to both slots simultaneously, preventing accidental file deletion or formatting. Separate status LEDs give instant visual confirmation of power and activity for each card independently.
