The Power of Convenient Versatility: Your work and gear require the versatility of using different types of memory cards. Maybe your camera uses both CFexpress Type B and SDXC UHS-II cards or you have several cameras that use a variety of cards. Or you’re a filmmaker recording separate video and audio content. Now you can empower yourself with maximum workflow efficiency by ingesting two different memory cards simultaneously with the OWC Atlas Dual CFexpress and SD Reader.

With a bus-powered design and integrated cable that neatly tucks into its base, the Atlas Dual CFexpress and SD Reader is conveniently ready for portable use with USB-C equipped Macs, Windows PCs, iPads, and Chromebooks.

Upgrades Your Workflow: Having a card reader that can meet the demands of professional broadcast, cinema, and photography is a must to maximize your creative time. You can start working with your content faster by upgrading your workflow with a reader that can deal with any media card that your work throws at you. This compact reader is not only extremely versatile but fast too as it “eats up” data at real-world tested speeds up to 1032MB/s. When every minute counts, the OWC Atlas Dual CFexpress and SD Reader OWC Beyond Fast™ performance makes the measurable difference you need to deliver projects on time.

Stay Safe and Informed: Confidence plays a big part in working smarter and more efficiently. You can prevent accidentally overwriting/deleting your precious data or reformatting your SD card in either slot with the Atlas Dual CFexpress and SD Reader’s Write Protection switch. And when you want a peace of mind update on each slot’s power and activity status, separate LEDs keep you clearly informed.

Ready For Wherever Your Work Takes You: Sized and weighing like a compact smartphone, you can easily slip the Atlas Dual CFexpress and SD Reader into a pocket or gear bag. That makes it ideal to pair with your notebook or USB-C tablet to create a lightweight yet mightily powerful capture and edit solution. Back at the studio or home office desktop, the USB-C port with OWC ClingOn support to secure a longer cable you already own lets you place the Atlas Dual CFexpress and SD Reader anywhere you desire. No worries if you accidentally connect that cable from a power supply to the USB-C port….the Atlas Dual CFexpress and SD Reader has built-in protection to prevent overpowering.

Effectively Cool Details: Details matter when it comes to obtaining the highest performance from your memory cards. The Atlas Dual CFexpress and SD Reader is built with a heat dissipating design and non-skid rubber feet to ensure a highly effective and silent cooling airflow around the entire reader, so your memory cards won’t overheat and throttle your speed.

After intensive stress tests with multiple full capacity cycles, the Atlas Dual CFexpress and SD Reader still delivers consistent sustained read and write performance from two Atlas memory cards while maintaining a safe temperature.

Innergize Your Workflow with Highest Performance and Reliability: OWC Innergize™ is the first stage of the Capture to Completion™ ecosystem of OWC products designed to seamlessly propel professional photographers, videographers, and content creators to the highest level of workflow performance and reliability. This OWC custom-designed app is a complete health, performance, and field upgrade management tool when using OWC Atlas memory cards with OWC Atlas readers and reader equipped products.

Health: Over time and use cycles, flash memory does wear out. Innergize verifies and reports the percentage of use life remaining. Now you can work with full confidence your OWC flash memory product will deliver the reliability you can trust.

Sanitize: Writes, deletes, and formatting all take their toll on memory cards. Innergize cleans and restores the flash memory performance of OWC memory cards so you can get the best results on every use.

Innergize gives OWC memory card users the ability to quickly upgrade their firmware in the field for full compatibility, additional performance enhancements, and bug fixes for optimal reliability.
