## Long description

The OWC Atlas Ultra 256 GB SDXC UHS-II memory card is a high-performance storage solution engineered for professional photographers and videographers who demand reliability and speed. With read speeds up to 300 MB/s and write speeds up to 250 MB/s, this card ensures efficient data handling for high-resolution workflows. It is built to handle intensive tasks, providing a minimum sustained write speed of 90 MB/s, which is essential for preventing dropped frames during high-bitrate video recording.
Advantages
This memory card offers exceptional durability, featuring a design that is resistant to dust, water, shocks, and X-rays, making it suitable for challenging field environments. Its UHS-II interface and V90 video speed class rating guarantee the performance necessary for capturing high-quality 4K and 6K video content without compromise. The rigorous quality control process ensures data integrity, allowing professionals to work with confidence during critical shooting sessions. Furthermore, its compatibility with a wide range of DSLR and mirrorless cameras, combined with backward compatibility for older SD devices, makes it a versatile tool for any camera kit.
Suitable for
Professional RAW photography with high-speed burst sequences
High-bitrate 4K and 6K video recording
Fast file transfers between camera and computer
Outdoor and studio photography in demanding conditions
When it may not be suitable
This card may be overkill for casual users or those using entry-level cameras that do not support UHS-II speeds or high-bitrate video formats. If your device does not require the V90 speed class, a more affordable, lower-specification card may be sufficient for your needs.
