Its 6-proof design protects against water, temperature extremes, X-rays, magnets, and drops. A full-size SD adapter is supplied, allowing immediate use in laptops, card readers, and cameras that accept standard SD slots. The rugged build suits daily transport in pockets or gear bags.

200 MB/s sequential read speed

Rated read performance reaches 200 MB/s, with write speeds up to 130 MB/s. This throughput lets you offload high-resolution photos and 4K footage rapidly and reduces game install or load times on compatible handhelds.
