256GB microSDXC with USB-C reader

This package pairs a 256GB microSDXC card with a proprietary USB 3.0 Gen 1 Type-C reader. The card carries Class 10, U3, A2 and V30 ratings for sustained capture. It targets dash-cam operators, drone pilots and Android device users who need a single kit for recording and offload.

Sustained write performance and environmental limits

The V30 and U3 markings guarantee a minimum sequential write of 30MB/s during long 4K UHD sessions. The A2 rating supports random IOPS for app-heavy workloads on smartphones and tablets. Operating range spans -25°C to 85°C with storage tolerance down to -40°C, plus water, wear and X-ray resistance up to 100mGy.

Upgrade path from lower-tier cards

The bundle replaces slower Class 10 or U1 cards that drop frames in 4K dash cams or drones. It also supersedes standalone cards when a USB-C reader is missing from the workflow. The jump is worth it when continuous 4K recording, app performance or extreme temperature reliability are required.
