Designed for photographers and digital media professionals, the PRO Plus UHS-I SDXC Memory Card from Samsung features a storage capacity of 512GB 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. Its V30/U3 class rating guarantees write speeds won't 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. The full-sized SD card reader connects to your host system via USB-A, so you can easily download files, either at home or on the go.
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.
