512 GB SDXC card for UHS-I cameras

This Transcend TS512GSDC340S card provides 512 GB of storage for DSLR cameras and camcorders that support the UHS-I interface. It meets Class 10, U3, V30 and A2 ratings so it can handle 4K video capture and fast burst shooting without dropped frames.

V30 and A2 ratings enable 4K and app performance

The V30 compliance guarantees a minimum sustained write speed of 30 MB/s for smooth 4K recording. The A2 specification improves random read and write performance for running applications directly from the card on compatible devices.

Check your device supports UHS-I and SDXC

Before ordering, verify that your camera or camcorder accepts SDXC cards and can use the UHS-I bus to reach the quoted 160 MB/s read and 90 MB/s write speeds. Devices limited to older SDHC or non-UHS buses will not achieve these rates.

Questions about this item

Does the 512 GB Transcend TS512GSDC340S card have a wear indicator or require periodic replacement?

The card uses 3D NAND flash with built-in error correction and wear levelling; no user-serviceable parts or scheduled replacement interval exists — it lasts until the flash blocks exhaust.

What sustained write speed can I rely on during long 4K recording sessions on this V30 U3 card?

The V30 rating guarantees a minimum 30 MB/s sequential write; the manufacturer rates maximum write at 90 MB/s, so sustained 4K capture stays above the 30 MB/s floor.

How much does the TS512GSDC340S heat up or draw power during all-day shooting?

SD cards draw very little power — typically well under 1 W — and run cool enough that no active cooling or thermal management is needed in normal camera use.
