Gigastone's 256 GB microSDXC delivers fast up to 130 MB/s reads, rugged waterproof and shockproof construction, and broad device compatibility, all with a 5-year warranty.

The SanDisk Extreme PRO 128 GB SDXC offers top-tier read performance and rugged durability, making it ideal for 4K UHD shooting and burst photography. Its write speed is modest for sustained high-bitrate video and it carries a premium price. Best suited for professionals needing reliability and fast off-loads without UHS-II support.
