The OWC Atlas Dual SD Card Reader is a high-speed, bus-powered, dual-slot external card reader designed for professional workflows. It simultaneously supports two SDXC UHS-II cards, offering transfer speeds exceeding 300 MB/s per slot (600 MB/s combined), ideal for fast photo and video file ingestion. The device connects via a USB 3.2 Gen 2 (10Gb/s) USB-C cable, which is integrated for portability and features built-in cable storage. A second USB-C port allows for the optional use of a longer cable in fixed installations. The reader is broadly compatible with Mac, Windows, Linux, iPad, and Chromebook systems, requires no drivers, and includes handy features such as write-protection switches, status LEDs per slot, non-skid rubber feet, and OWC’s Innergize™ management tool for health and performance of OWC Atlas memory cards. The compact, pocket-sized design and 2-year warranty make it suitable for both travel and studio use.
