Optimized for demanding uses in professional photography and cinematography, the 256GB Essential UHS-II SDXC Memory Card from Exascend lets you quickly record and offload footage, even when working with extreme bitrates, to help ensure there are no dropped frames. This card features a storage capacity of 256GB and utilizes the UHS-II bus to deliver maximum sequential read speeds of 300 MB/s and maximum sequential write speeds of 260 MB/s. Thanks to its V90 speed class rating, minimum write speeds are guaranteed not to drop below 90 MB/s, making this card suitable for 8K video and above.
To help facilitate card usage in almost any environment, as well as keeping your content safe, Exascend has built the Essential series with a rugged design that can withstand water, dust, impact, X-rays, magnets, and temperatures ranging from -13 to 185°F. To help protect your data from being accidentally deleted, there is a built-in write protect switch.
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.
