The SanDisk Extreme Plus SD UHS-I memory card utilises SanDisk QuickFlow technology for a read speed of up to 170 MB/s, allowing you to transfer your media files even faster. With write speeds of up to 80 MB/s and UHS Speed Class 3 (U3), you can capture high-resolution, lossless 4K UHD video recordings. Another advantage of the card is its weather resistance. It is waterproof, shockproof, and equipped to handle harsh conditions, so you won’t have to worry about your recordings while on the go.
