Does it work in the Nintendo Switch 2?

Yes. It is a microSD Express card, the type the Switch 2 uses for game storage, and buyers report it working there.

Will it be fast in my phone or camera?

Only if the device has a microSD Express slot. In standard microSD slots it runs at the slower speed that slot supports.

How much can 512GB hold?

It holds a large Switch 2 game library plus photos and video. Exact game counts depend on each game's size.

It is rated water, shock, temperature and magnet resistant, so it handles travel and rough handling better than a plain card.

What comes in the box?

The card itself. You supply the device and any adapter you need for full-size SD slots.

Is it worth it over a cheaper standard microSD card?

For a Switch 2, yes: standard cards run slower there. For older devices without an Express slot, a standard card gives the same speed for less.
