128GB SDXC UHS-I U3 V30 Card

The Transcend 500S is a 128GB SDXC memory card built on MLC NAND flash for advanced DSLR cameras and HD camcorders. It meets Class 10, UHS-I U3 and V30 specifications, delivering read speeds up to 95MB/s and write speeds up to 60MB/s for reliable 4K video capture.

Who this suits and who should look elsewhere

This card suits photographers and videographers using UHS-I compliant DSLRs or camcorders who need sustained 4K recording without dropped frames. It is not for users requiring capacities beyond 128GB or devices that only support the older SDHC standard.

Capacity and headroom

With 128GB of storage, the card holds thousands of high-resolution photos and extended 4K footage sessions. The V30 rating guarantees a minimum 30MB/s write speed for smooth video, while the 95MB/s read speed accelerates offload workflows. U3 and V30 compliance is validated for the 64GB to 256GB range.

Questions about this item

Does my camera need a UHS-I SDXC slot to use this 128 GB card?

Yes — the card is SDXC format and rated UHS-I U3 V30, so the host must accept SDXC cards and support the UHS-I bus for the rated speeds.

Will the 95 MB/s read speed still be reached in an older UHS-I body that only advertises Class 10?

The card will fall back to the host’s maximum UHS-I transfer rate; Class 10 guarantees 10 MB/s minimum, but the 95 MB/s peak requires a UHS-I capable device.

How can I confirm the card sustains 60 MB/s write for 4K video after formatting?

Run a sustained write benchmark or record a long 4K clip; continuous writing at or above 60 MB/s without dropped frames shows the V30 rating is being met.
