The SanDisk 256 GB Extreme PRO SDXC UHS-I offers top-tier read/write performance (200 / 140 MB/s) and rugged protection, making it a strong choice for 4K creators. Its UHS-I bus limits it on cameras that can exploit UHS-II bandwidth, and some users report speed variance with cheaper readers.

The Lexar Gold Series 256 GB UHS-II SDXC card offers professional-grade speed and durability, with V60 video support and a lifetime warranty, making it suitable for demanding 4K video and high-burst photography. Performance is limited to UHS-II hosts and the card carries a premium price.
