The Gigastone 256 GB microSDXC offers strong 4K video capability, solid durability and a unique 5-year data-recovery warranty, making it a dependable mid-range choice. Real-world write speeds fall short of the advertised maximum, which may limit high-bit-rate use cases.

The Lexar E-Series 256 GB microSDXC card offers solid read performance and rugged durability for everyday mobile use, but its modest 30 MB/s write speed limits 4K video capture. It includes an SD adapter and a long-term warranty, making it a reliable choice for smartphones and tablets.
