OWC 256GB Atlas Ultra High-Performance SDXC UHS-II V90 Memory Card

The OWC or Other World Computing 256GB Atlas S Pro UHS-II SDXC Memory Card features a storage capacity of 256GB and takes advantage of the UHS-II bus to support high-bitrate video up to 8K, high-resolution raw and JPEG images, and continuous shutter bursts. Designed for social media influencers, visual arts hobbyists, drone pilots, creative professionals, and more, this card features sequential read speeds up to 290 MB per second and sequential write speeds up to 276 MB per second. Thanks to its V90 speed class rating, minimum write speeds are guaranteed not to drop below 90 MB per second.
To help facilitate card usage in almost any environment, as well as keep your content safe, OWC built the Atlas Pro with a rugged design that can withstand impacts, bends, shocks, ESD, UV rays, X-rays, and temperatures ranging from negative 13 to 185 degrees F. A built-in write-protect switch further helps safeguard your content against accidental deletions, while pSLC (pseudo-Single-Level Cell) flash technology and an endurance rating of 7310TB total bytes written (TBW) further help provide consistent performance, endurance, and reliability.
UHS-II media achieves its speed through an extra row of pins and, while this card has been designed for cameras and card readers that are UHS-II or V90 compatible, it may be used in devices that do not support UHS-II or V90. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-II and V60, which support minimum write speeds of 60 MB per second, UHS-II and V30, which support minimum write speeds of 30 MB per second, or UHS-I and U3, which also supports minimum write speeds of 30 MB per second. If your device does not support U3, this card is compatible with the U1 and Class 10 standards, each of which guarantees minimum write speeds of 10 MB per second.
