The OWC Atlas Ultra SDXC is a 512GB UHS-II V90 memory card for professional photographers and videographers who need fast storage for RAW burst photography and high-bitrate 4K or 6K recording, with a minimum sustained write speed of 90 MB/s.
Recommended For
- Sports, wildlife, and action photographers using a UHS-II SDXC camera who shoot long RAW bursts and want a V90 card’s minimum 90MB/s sustained write speed to help keep up with continuous capture.
- Video creators whose compatible DSLR or mirrorless camera records high-bitrate 4K or 6K to SD and calls for V90 media; the card is designed for sustained recording, while actual mode support depends on the camera.
- Photographers and videographers covering long events or multi-day assignments who want 512GB on one SDXC card to hold more footage before swapping or offloading cards.
- Field shooters working around dust, water, or rough handling who want a card specified as IP67 dust-proof and waterproof, and resistant to bending, shock, and X-rays.
- Creators who regularly transfer large shoots to a computer and have a UHS-II card reader: an independent test measured up to 287MB/s read and 225MB/s write in one benchmark, though results vary by test setup.
