Actual transfer speed can vary with the host device, card reader, and conditions of use. The SD adapter provides another way to use the microSD card with an SD-enabled host, such as a computer or camera.

Why it’s worth it

Its 256GB capacity gives you room for photos, video, music, apps, and documents, while the microSDXC format suits compatible portable devices.
