Will this work in a Nintendo Switch 2?

Yes. The Switch 2 uses microSD Express, and this card's PCIe 3.0 interface matches it. Expect load times close to the console's internal storage.

Does it work in an older phone or camera?

It fits the slot, but devices without microSD Express fall back to UHS-I speeds. You would pay for speed those devices cannot use.

How fast is it in a normal card reader?

Only an Express-capable reader reaches the 800 MB/s read rating. A standard UHS-I reader caps the card at UHS-I speed.

What does the 200TB endurance rating mean?

It is the total data the card is rated to write over its life. That is far above typical UHS-I cards, which suits heavy game installs and video recording.

Is it durable enough for outdoor use?

Samsung rates it resistant to water, temperature extremes, drops, shock, magnets and X-rays. Keep it in a case when it is not in a device.

The card itself. A reader or adapter is not included, so you need an Express-capable reader to get full speed on a computer.

Our take on the Samsung 512GB P9 microSD Express Memory Card

The Samsung P9 is a 512GB microSD Express card built on PCIe 3.0 and NVMe 1.3, so it reads at up to 800 MB/s — several times faster than UHS-I microSD cards. That speed matters for devices that support the SD 7.1 Express interface, such as the Nintendo Switch 2 and newer handhelds, card readers and some cameras. It is rated for up to 200TB written and carries water, temperature, drop, shock, magnetic and X-ray protection. Buyers with older UHS-I-only gear get no benefit from the Express interface and should look at a UHS-I card instead.
