Designed to excel in professional photography and high-end cinematography, the 256GB Catalyst UHS-I SDXC Memory Card from Exascend lets you keep up with extreme resolutions and rapid-fire shutter bursts. This card features a storage capacity of 256GB and utilizes the UHS-I bus to deliver maximum sequential read speeds of 180 MB/s and maximum sequential write speeds of 150 MB/s. Thanks to its V30 speed class rating, minimum write speeds are guaranteed not to drop below 30 MB/s, which is fast enough to handle 4K and Full HD video, plus shutter bursts.

To help facilitate card usage in almost any environment, as well as keeping your content safe, Exascend has built the Catalyst 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.

Please note that if your camera does not support minimum write speeds of 30 MB/s, this card is compatible with the U1 and Class 10 standards, each of which guarantees minimum write speeds of 10 MB/s.
