SanDisk Extreme PRO 128GB
Score: 84/100
Gigastone SD Card 128GB
Score: 71/100Rankings
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.
The Gigastone 128 GB SDXC card offers a solid capacity and includes a convenient USB-C reader, backed by a 5-year data-recovery warranty. Its performance is limited by the lack of waterproofing and unspecified write speeds, making it less ideal for demanding 4K recording. Best suited for casual photographers needing extra storage and a handy reader.
