Transcend TS256GSDC300S 256GB SDXC Card

This 256GB SDXC memory card is built for UHS-I compatible cameras and camcorders. It carries Class 10, U3 and V30 ratings on 3D NAND flash. The card delivers the speed and capacity needed for 4K video and high-resolution stills.

Who this suits and who it does not

Photographers and videographers recording 4K footage on UHS-I devices will benefit from the sustained write performance. Buyers needing faster offload speeds or higher capacities should look at other options.

Deciding specification — V30 sustained write

The V30 rating guarantees a minimum 30 MB/s sequential write speed, which is the threshold for uninterrupted 4K recording on supported hardware. Maximum read reaches 95 MB/s and maximum write reaches 45 MB/s.

Questions about this item

Will this 256 GB SDXC card work in my older camera that only supports SDHC?

No, SDXC cards like this 256 GB model are not backward-compatible with SDHC-only devices; the camera must explicitly support the SDXC standard.

How can I confirm the card is delivering the rated 95 MB/s read speed after I format it?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader; sustained sequential reads should approach 95 MB/s.

Does the package include a card reader or adapter, or do I need to buy one separately?

Only the 256 GB SDXC card is included; a UHS-I compatible reader or microSD adapter must be purchased separately.
