Yes they can. MicroSDExpress is fully backwards compatible with MicroSDXC. So any device that can read mSDXC can read the card, at regular SDXC speeds.

Really good price for a 256gb micro sd card in this current era of storage prices. Probably not good for something like a dash cam, I would go with one of the Endurance variants. Good for a Nintendo switch.

Imagine how miserable your life would have to be if you can only afford one console so you build your entire personality around hating the other ones.

This 256GB Samsung microSD Express card stands out as a strong price on fast storage, especially for Switch 2 and other devices that support SD Express. It is also described as a solid fit for Nintendo Switch, with faster PC reads when paired with an Express reader and continuous writes rated at 30MB per second. The main caution is compatibility, since non Express devices fall back to UHS I speeds around 100MB per second. For dash cams and other constant recording gear, endurance cards are the safer match.

  • The card can work in devices that support microSDXC, including Nintendo Switch use cases.

  • The card can deliver a speed boost when used with an SD Express-capable device.

    ThirstyCruzJollyCrayon539

  • The card can run at regular UHS-I speeds in non-SD Express readers, which may still be usable for general storage.

  • The card reportedly works in an Insta360 X5 camera setup for everyday recording.

    AndyP5910AndyP5910

  • The card may not be suitable for dash cams because video recording can involve constant writes and faster wear.

    Ch3apSk8teOCNewbie

  • The card can deteriorate faster in continuously recording camera scenarios due to constant write activity.

    bobasuarbobasuar

  • The card's higher speeds require SD Express support, otherwise it falls back to about 100MB/s in UHS-I mode.

    JollyCrayon539agate

  • The card can be fragile and may snap or break during removal from packaging.

Heads up. This won't work at high speeds unless you have a device that supports the sd express standard. Otherwise it will only run at uhs-1 100mb

Any reason NOT to get one of these for a DJI Drone? The drones are all UHS-I so this Samsung P9 Express should max out the speed capabilities.DJI recommends a Lexar Professional Silver Plus Micro SD Card, UHS-I, C10, U3, V30.
I just bought for that exact drone. Grok said it is a good choice.

Why not a dash cam?
It's probably fine. I haven't seen any benefit to using supposedly long life versions of cards and hard drives. I have "regular" cards in security cameras recording 24/7 that have been working for years now, though that doesn't mean cards made today will be as durable. Smaller capacity cards that don't push the limits of the technology will tend to be more durable. One of the shortest life drives I've had is a Western Digital Purple, ironically shorter life than my non-long life drives. That's just my own experience, not saying it'll work out that way for anyone else as I'm sure there're others out there with the opposite experience.

Tested around 80MB/s read/write in UHS-I card reader. Not bad for the price. True SD express only has very limited use cases like switch 2.

That's 256GB, not 512GB microSD Express though. I don't think the 512GB microSD Express ever dipped down to $30-35.
Oh yea, I was just comparing the march deal with this one. For sure not 512gb for $40, it would be sold out within seconds.
