{"product_id":"owc-atlas-dual-cfexpress-sd-card-reader","title":"OWC Atlas Dual CFexpress + SD Card Reader","description":"\u003cp\u003eThe bottleneck in most professional photo and video workflows isn't the camera, the lens, or the edit suite — it's the 30 seconds you lose every time you swap a card, plug in a cable, and wait for a single slot reader to catch up. The OWC Atlas Dual CFexpress + SD Card Reader removes that bottleneck entirely. It reads CFexpress Type B and SDXC UHS-II cards simultaneously through a single USB-C connection at up to 1,032 MB\/s, which means you can ingest footage and pull stills at the same time, not one after the other.\u003c\/p\u003e\n\u003cp\u003eThe design is genuinely thought through. The USB-C cable is integrated and tucks neatly into the base of the unit so there's nothing to lose in a bag, nothing to forget on a hotel desk. It's bus-powered — no wall adapter, no separate cable — and sized like a compact smartphone so it fits in a jacket pocket without drama. A second USB-C port with OWC ClingOn support lets you connect a longer cable when you're working at a desk and want the reader somewhere convenient rather than dangling from your laptop. There's also a write protection switch covering both slots simultaneously, which is exactly the kind of thing you want when a DIT is working fast and an accidental reformat would ruin someone's day.\u003c\/p\u003e\n\u003cp\u003eThe heat dissipating design keeps both cards running at full speed even under sustained load. Two independent LEDs show you the status of each slot at a glance. It's compatible with USB-C Macs, Windows PCs, iPads, Chromebooks, and Android devices — no driver installation required. For Atlas memory card users, OWC's free Innergize app connects to the reader for health monitoring, flash performance restoration, and field firmware upgrades without needing to find a laptop and a full internet connection.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual-slot: CFexpress Type B and SDXC UHS-II simultaneously\u003c\/li\u003e\n\u003cli\u003eUp to 1,032 MB\/s real-world tested read performance\u003c\/li\u003e\n\u003cli\u003eUSB 3.2 Gen 2 (10Gb\/s) host connection via USB-C\u003c\/li\u003e\n\u003cli\u003eIntegrated USB-C cable tucks into base — nothing to lose\u003c\/li\u003e\n\u003cli\u003eBus-powered — no wall adapter required\u003c\/li\u003e\n\u003cli\u003eSecond USB-C port with OWC ClingOn support for desk use\u003c\/li\u003e\n\u003cli\u003eWrite-protection switch covers both slots simultaneously\u003c\/li\u003e\n\u003cli\u003eSeparate activity and power LEDs per slot\u003c\/li\u003e\n\u003cli\u003eHeat dissipating design for sustained performance\u003c\/li\u003e\n\u003cli\u003eNon-skid rubber feet for stable desktop use\u003c\/li\u003e\n\u003cli\u003ePlug and play — no drivers needed\u003c\/li\u003e\n\u003cli\u003eInnergize enabled — health monitoring, performance optimisation, field firmware upgrades\u003c\/li\u003e\n\u003cli\u003e2-year OWC Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's in the Box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOWC Atlas Dual CFexpress + SD Card Reader\u003c\/li\u003e\n\u003cli\u003eQuick Start Guide\u003c\/li\u003e\n\u003cli\u003e2-Year OWC Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Q\u0026amp;A\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdetails open=\"\"\u003e\n\u003csummary\u003e\u003cstrong\u003eQ: Can I read a CFexpress card and an SD card at the same time?\u003c\/strong\u003e\u003c\/summary\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes — that's the whole point.
