256GB microSDXC for creators and gamers

The Silicon Power SP256GBSTXLA2VC2 is a 256GB microSDXC card rated A2, UHS-I U3 and V30. It targets content creators and gamers who need reliable storage for 4K video capture and fast app loading on drones, action cameras, tablets and handheld consoles. A bundled USB reader is included for quick offloading.

Sustained write performance for long recordings

The card delivers write speeds up to 150MB/sec and read speeds up to 170MB/sec under the U3 and V30 ratings, maintaining the throughput required for continuous 4K Ultra HD recording without dropped frames. 3D TLC NAND and dual ECC error correction preserve data integrity during extended sessions, while the DDR200 specification enables the peak 170MB/sec read rate when paired with a compatible reader.

Upgrade from slower Class 10 or U1 cards

Moving from a basic Class 10 or U1 card removes the bottleneck that causes stuttering 4K footage and sluggish app launches. The A2 rating and V30 sustained write speed make the jump worthwhile for anyone recording high-bitrate video or running applications directly from the card. Buyers who need capacities beyond 256GB or require UHS-II speeds for professional cinema workflows should look elsewhere.

Questions about this item

Does the SP256GBSTXLA2VC2 run hot or draw extra power when recording 4K video all day?

The card has no moving parts and consumes minimal power; its 3D TLC NAND and UHS-I U3 rating handle sustained 4K capture without generating noticeable heat.

What host device or reader do I already need to reach the 170 MB/s read speed?

A device or reader that supports UHS-I and the DDR200 specification is required to achieve the rated 170 MB/s read performance.

Will this A2-rated microSDXC card work properly in my older action camera that only specifies UHS-I U1?

Yes, the card is backward compatible with UHS-I U1 devices; it will operate at the host's maximum supported speed class.
