The Atlas S Pro UHS-II SDHC Memory Card from OWC / Other World Computing 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/s and sequential write speeds up to 275 MB/s. Thanks to its V90 speed class rating, minimum 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 Pro with a rugged design that can withstand impacts, bends, shocks, ESD, UV rays, X-rays, and temperatures ranging from -13 to 185°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 910TB 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 / 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.

Most unopened items sold by Melrose Inc. in new condition and returned within 30 days will receive a refund or exchange. The return window for items sold online begins once the order has been invoiced. Invoicing happens when any part of the order is shipped, delivered by a courier service or made ready for pick up.

Software is not returnable and not refundable. All sales are final. This is generally part of all webcarts selling software. It is buyer beware. The reason for this is once an end-user customer sees a License Code then that code is 'spoiled' because they can use it to gain access to the software.  Once a License Code is registered by a customer that product is available to that customer and therefore the code cannot be returned.
