Designed for photographers and other digital media professionals, the PRO Plus UHS-I SDXC Memory Card from Samsung features a storage capacity of 256GB and takes advantage of the UHS-I bus to support read speeds up to 180 MB/s and write speeds up to 130 MB/s. Thanks to its V30/U3 class rating, write speeds are guaranteed to not drop below 30 MB/s, making it suitable for 4K, Full HD, and 3D video, as well as raw and JPEG captures, plus rapid shutter bursts.
As with most Samsung cards, this memory card is resistant to water, X-rays, magnets, shocks, drops, and wear. It is also able to withstand temperatures from -13 to 185°F so you can take it with you into extreme environments, including snow and deserts. If you're concerned about protecting the content on this card, there is a built-in write-protect switch.
