OWC 128GB Atlas Ultra UHS-II SDXC Memory Card

The 128GB Atlas Ultra UHS-II SDXC Memory Card from OWC / Other World Computing features a storage capacity of 128GB and takes advantage of the UHS-II bus to support advanced DSLR/mirrorless functions such as continuous shutter bursts and rapid shooting, as well as raw and JPEG captures. This card is also well-suited for video capture, including 6K, 4K, Full HD, and 3D video. It can achieve max sequential read speeds of up to 300 MB/s and max sequential write speeds of up to 250 MB/s. Thanks to its V90 speed class rating, minimum sustained write speeds are guaranteed not to drop below 90 MB/s.

To help facilitate card usage in almost any environment, as well as keeping your content safe, OWC built the Atlas Ultra with a design that is bend, shock, and X-ray resistant, as well as an IP67 rating, meaning it is dust and waterproof. It is also able to withstand temperature extremes from -13 to 185°F.

UHS-II media achieves its speed through an extra row of pins and, while this card has been designed for cameras that are UHS-II / V90 compatible, it may be used in devices that do not support UHS-II / 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 supports minimum write speeds of 60 MB/s, UHS-II and V30, which supports minimum write speeds of 30 MB/s, or UHS-I and U3, which also supports minimum write speeds of 30 MB/s. 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/s.
