Built for creators and gamers

The Samsung T9 microSDXC card delivers 512 GB of storage for cameras, handheld consoles, smartphones and tablets. It targets users who need fast, reliable media for 4K video capture and large game libraries on the go.

Capacity and headroom

With 512 GB you can store extensive photo archives and multiple AAA titles without constantly deleting files. The UHS-I interface caps sequential reads at 200 MB/s and writes at 130 MB/s, so sustained high-bitrate recording will eventually hit that ceiling.

U3 V30 A2 speed rating

The card carries UHS Speed Class 3, Video Speed Class 30 and Application Performance Class 2 ratings, guaranteeing minimum sustained write performance for 4K video and quicker app loading. If your workflow demands faster sustained throughput than UHS-I provides, this card will not meet that need.

Questions about this item

Will the 200 MB/s read speed work with my older UHS-I card reader?

Yes, the card uses the UHS-I interface and is backwards compatible with older UHS-I readers, though speeds will be limited by the reader's maximum capability.

How can I verify the V30 and A2 ratings are performing after I install it?

Run a benchmark tool such as CrystalDiskMark or the Samsung Magician software to confirm sustained write speeds meet the 30 MB/s V30 minimum and check random IOPS for A2 app performance.

Does the package include the SD adapter or do I need to buy one separately?

The supplier title confirms the card ships with an SD adapter included, so no separate purchase is required for use in full-size SD slots.
