High-capacity microSDXC card

The Transcend TS256GUSD300S-A provides 256GB of storage in a microSDXC form factor. It carries a Class 10 speed rating with a maximum read speed of 95 megabytes per second and a write speed of 100. An SD adapter is included for broader device compatibility.

Suited for mobile recording and expansion

This card serves users who need ample space for apps, photos and Full HD video on smartphones, tablets or action cameras. The A1 rating supports smoother app performance. Buyers who require sustained write speeds for high-bitrate 4K capture or professional workflows should look at higher-tier options.

256GB with Class 10 headroom

The capacity comfortably holds large media libraries and offline maps. Sequential reads up to 95 and writes up to 100 handle typical burst shooting and file transfers. Workloads demanding continuous high-throughput recording beyond the Class 10 guarantee will exceed the card’s rated performance envelope.

Questions about this item

What device slot do I need for the TS256GUSD300S-A microSDXC card to work?

You need a microSDXC-compatible slot; the card also includes a full-size SD adapter for devices that only accept standard SD cards.

Will the 95 MB/s read speed and Class 10 rating work with my older UHS-I camera?

Yes, the card is UHS-I U3 and backward compatible with UHS-I hosts, though sustained write performance will match the host's maximum capability.

How can I verify the card delivers the advertised 95 MB/s read and 100 MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a PC with a UHS-I reader and compare sequential results to the rated figures.
