Combining industrial strength and reliability with fast performance, the 256GB BLACK UHS-II SDXC Memory Card from Delkin Devices features a storage capacity of 256GB and takes advantage of the UHS-II bus to support advanced DSLR 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 8K, 4K, 3D, HDR, 360°, HFR, and Full HD video, and can achieve maximum read speeds of up to 300 MB/s and maximum write speeds of up to 250 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, Delkin has built its BLACK Series with a rugged design that can withstand 45 pounds of impact. It is also dust, x-ray, water, and shockproof, and resistant to temperature extremes from -13 to 185°F. In order to further enhance reliability and functionality, the BLACK Series was built with no write-protect switch or plastic ribs that run in between the contacts on the back of the card.
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.
