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.

Common Questions (5)

  • Usually not, because phones, cameras, and the original Switch generally run it at UHS-I speeds, where some regular microSD or UHS-II cards can be faster and cheaper. It is mainly useful when the device has dedicated SD Express support.

    crypticpurposecrypticpurposecrypticpurposeMWink

  • It works in any device that accepts microSD, but without SD Express hardware it falls back to UHS-I speeds. The speed advantage only shows up in devices designed for MicroSD Express, such as Switch 2.

    ItsYaBoiJohn25crypticpurposeWooHoo2You

  • No, it reportedly does not work with a modchipped Switch.

    droptopjim

  • One benchmark showed about 87 MB/s sequential read and write and about 6 MB/s random read and write. That was described as strong random-card performance, especially because many cards have much lower write speeds than read speeds.

    Y0tsuya

  • In a DJI Osmo test, it was only reaching about 40 MB/s and was considered too slow for 4K 60 FPS capture. DJI was also cited as recommending Kingston Canvas and Lexar Silver instead.

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.
I wouldn't say "almost nothing else uses them"....but nothing else demands the extra theoretical speed. Everything that takes MicroSD can use a microSD Express card but will be limited by the host device's max transfer rate.

When the AI bubble starts to pop, prices will plummet. But that's at least another year out.
AI, tariffs, inflations, record weak dollar, high gas prices (driving up every stage of production / retail logistics)...but yes...blame AI only.

I didn't say it was only AI, or even that prices will go back to where they were before. Prices will plummet from where they are at least temporarily as AI-specific orders get cancelled as the industry pulls back.

You also didn't say if Mercury being in retrograde should be taken into account...can we also assume that was part of your point as well?

FWIW, I'd rather not put words in your mouth. Since you didn't mention it, I figured you did not feel it worth factoring in.

lol. Yes, AI is the only materially relevant factor to the point that prices will drop when AI orders suddenly decrease. It's basic supply and demand. Other factors will affect prices too, but unless they change with the change in AI orders, they won't offset the prices decreasing as demand from AI decreases suddenly.

IMO all the factors I mentioned are of similar importance / influence thus why I think omitting them seems inaccurate (at best).

Would this work great for Insta 360 X5 or Ace Pro 2, or SanDisk Extreme Pro better?

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.
Are there any phones that use uhs-ii?

If you actually do the work, P90x is very effective.

So what if "it will only work at UHS-I speed"? There are no name brand 256gb microsd at this price in this climate.
