Transcend 64 GB SDXC 340S card

This Transcend SDXC 340S memory card delivers 64 GB of storage for UHS-I compatible DSLR cameras and advanced camcorders. It uses high-quality 3D NAND flash and meets UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) standards for sustained write performance.

Photographers and videographers capturing 4K footage

The V30 rating ensures smooth, uninterrupted 4K video recording on supported UHS-I devices. Users needing higher capacities, faster UHS-II speeds, or CFexpress compatibility should consider alternative formats.

U3 and V30 speed class rating

This single specification guarantees a minimum sustained write speed of 30 MB/s, which is the decisive factor for reliable 4K video capture on UHS-I host devices. Without this rating, frame drops or recording stops can occur.
