The Samsung PRO Plus microSDXC 512GB is the EVO’s harder-working sibling: up to 160MB/s reads and 120MB/s writes — the write speed being the real story, because that’s what clears camera buffers and swallows 4K streams without blinking. U3/V30/A2 rated, 6-proof protected, built for cards that earn their keep.
Write speed
120MB/s — the pro difference
Writes are where cheap cards choke: 120MB/s keeps drones, action cams and burst photography flowing, and makes the card usable as working storage, not just a shelf.
Fast both ways
160MB/s reads
Offloads and file moves at the practical top of UHS-I — a day of footage transfers while you pack the kit.
Dependable
V30 + A2 + 6-proof
Sustained 4K guarantee, app-class random performance, and Samsung’s six-way protection against water, temperature, X-ray, magnets, drops and wear.
Right choice if you…
✔ Shoot 4K on drones, action cams, phones — heavily
✔ Offload big days often — write speed pays twice
✔ Run a Steam Deck or heavy app storage (A2)
✔ Want Samsung’s fastest mainstream microSD
Consider something else if…
✖ You mainly store media — the EVO Plus gives more GB per pound
✖ Dashcam loop duty — endurance cards fit that pattern
✖ Full-size SD camera — different slot
