Designed for photographers and other digital media professionals, the 64GB PRO Plus UHS-I SDXC Memory Card from Samsung features a storage capacity of 64GB and takes advantage of the UHS-I bus to support read speeds of up to 100 MB/s and write speeds of up to 90 MB/s. Thanks to its V30/U3 class rating, write speeds are guaranteed not to 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, shock, drop, and wear while also being able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow and deserts. If you're concerned about protecting the content on this card, there is a built-in write-protect switch.
