This is a micro sd express card. It's faster than a standard micro sd card.

This one is compatible with a Switch 2.

It's only faster for devices designed for MicroSD Express, like the Switch 2. For everything else, it will run at UHS-I speeds, so you won't see any benefit spending the premium for one of these in something like the original Switch, or phones with expandable storage.

Community Reviews

This Samsung microSD Express card is mainly about Switch 2 support and faster storage in devices built for the Express standard. It is backwards compatible with regular microSD slots, but in older Switches, phones, and most cameras it falls back to UHS I speeds, so the premium brings little benefit there. Benchmarks put it around 87 MB per second sequentially, with much lower random speeds, and the card has been flagged as incompatible with a modchipped Switch. At $48 for 256GB, it stands out as a name brand option in a tight market.

  • The card can deliver higher performance in devices designed for MicroSD Express, such as a Switch 2.

  • The card is backwards compatible with microSD slots, so it can still function in standard microSD devices.

    crypticpurposecrypticpurpose

  • CrystalDiskMark testing reportedly shows strong sequential read and write speeds around 87-87MB/s.

  • The card can fall back to UHS-I speeds in phones and other devices without MicroSD Express hardware support.

    crypticpurposecrypticpurpose

  • The card can jitter in 4K+ devices during fast-moving action, and testing may suggest the cards are not legit.

    TXGoat

  • A modchip in a Switch can prevent the card from working.

  • The card may be too slow for DJI Osmo use cases like 4K 60 FPS, with DJI recommending other brands instead.

Agreed. The price likely won't be that low again with what is going on in the world. However, we don't know for sure as crazier things have happened.

I thought the same thing until I started trying to use them in a few 4k+ devices and saw all the jittering during fast moving action.... I went ahead and plunked down $300 for a couple of high speed cards, but the tests I've run on them have me thinking that they're not legit.... SMH

It will work with any phone with a MicroSD slot, but only at UHS-I speeds, so a UHS-II card will be considerably faster (not to mention cheaper, and available in larger sizes).


As far as I know, there aren't any phones currently available or on the horizon that have dedicated PCIe lanes for external storage, which is what makes MicroSD Express ao much faster, so, while the cards are backwards compatible, the backwards compatibility mode is significantly slower than the fastest regular MicroSD cards.

The cards are probably fine.


MicroSD Express is a new storage standard, and, unless your camera has the hardware to support it (and there aren't any on the market that do), the card can only run in backwards-compatibility mode, which is UHS-I speed, or ~1/3 as fast as UHS-II MicroSD cards.


There is pretty much only one reason to buy a MicroSD Express card right now is for a Nintendo Switch, because almost nothing else uses them.

This isn't a MicroSD, it's a MicroSD Express -basically a tiny NVMe SSD fit into the MicroSD format. it's technically backwards compatible, but only at UHS-I speeds, so there really isn't any point unless you will use it with a Nintendo Switch or one of the handful of exotic devices that support it.
The price for regular MicroSD cards is definitely also crazy right now, but these ones were always around this price.
