128GB SDXC UHS-I U3 Card

The Transcend TS128GSDC300S is a full-size SDXC memory card with 128GB capacity. It carries Class 10, UHS-I U3 and Video Speed Class 30 (V30) ratings built on 3D NAND flash. The card targets DSLR cameras, HD camcorders and other devices that use the SDXC format.

Photographers needing V30 sustained write

This card suits photographers and videographers who need guaranteed minimum write speeds of 30 MB/s for Full HD and 4K recording. Users who require the faster UHS-II bus or higher video speed classes will not meet their throughput needs with this card. Buyers with older hardware limited to SDHC should verify SDXC support before purchase.

UHS-I U3 speed class decides fit

The single specification that decides compatibility is the UHS-I U3 rating, which guarantees 30 MB/s minimum sequential write. If the host device demands UHS-II or a higher video speed class, this card will not satisfy the requirement.
