Our take on the Samsung MB-MD512S 512 GB MicroSDXC UHS-I Classe 10

The Samsung PRO Plus 512GB is a UHS-I microSDXC card built for gaming handhelds, action cameras and drones. It stands out with sequential reads up to 180 MB/s and writes up to 130 MB/s, plus the A2 app performance rating for faster app and game loading. It carries six-way protection (water, temperature, X-ray, magnetic, drop, wear) and a 10-year limited warranty. Compared with UHS-II cards it is slower on paper, but it costs less and works in devices that don't support UHS-II.

Questions and answers

Is the Samsung PRO Plus 512GB fast enough for a Steam Deck or Switch?
Yes. Its A2 rating and 180 MB/s reads make game loading quick on both. It is not the fastest card on paper, but it is fast enough that load times are short.
Does it work in a drone or action camera?
Yes. It is rated for 4K video and handles the write speeds those devices need. The water, temperature and X-ray protection suits outdoor use.
What is included in the box?
The card itself. Some packs add an SD adapter, but not all, so check the listing if you need one.
How does it compare with a UHS-II card?
UHS-II cards are faster in compatible readers, but most phones, consoles and cameras do not use that extra speed. The PRO Plus is the better fit for those devices.
Is 512GB enough for a game library?
It holds a large library of Switch or Steam games, but big titles can take tens of gigabytes each. Heavy 4K video shooters may want the 1TB version.
Where is the Samsung MB-MD512S 512 GB MicroSDXC UHS-I Classe 10 cheapest?
