Our take on the Samsung 512GB T9 Micro SDXC Card UHS-I

The Samsung T9 is a 512GB microSDXC card rated UHS-I U3, V30 and A2, with a claimed read speed of 200 MB/s. The A2 rating means it handles app installs and small-file reads better than plain U1 cards, and V30 covers 4K video recording on phones, drones and action cameras. It competes with SanDisk Extreme and Lexar cards that offer similar V30/A2 ratings but usually lower read speeds. It suits people who move large files or record high-bitrate video and want a card that also works well for apps.

What people mention

Questions and answers

Is the Samsung T9 microSD card fast enough for 4K video?
Yes. The V30 and U3 ratings cover 4K recording on phones, drones and action cameras. Very high-bitrate or long clips may still hit slower sustained write speeds.
What is the difference between the T9 and the Evo Plus?
The T9 claims a higher 200 MB/s read speed and carries an A2 rating for app performance. The Evo Plus is slower on paper and aimed at everyday storage rather than app installs.
Will this card work in a Nintendo Switch?
Yes. The 512GB capacity and A2 rating suit game downloads and fast loading. Format it in the console before use.
Does it come with an SD adapter?
Not always. Some packs include one and some do not, so check the bundle before buying if you need full-size SD compatibility.
Is 512GB enough for a phone or tablet?
For most people, yes. It holds a large photo and video library plus apps, though heavy 4K recording fills it faster than mixed use.
Does it work with UHS-II devices?
It works, but at UHS-I speeds. Devices with UHS-II slots will not get the extra bandwidth from this card.
Where is the Samsung 512GB T9 Micro SDXC Card UHS-I cheapest?
At Newegg, for $184.95, as of our latest check.
