Dual 16 GB SDHC cards with holder

This pack contains two Transcend TS16GSDC300S cards, each offering 16 GB of storage. Both cards use the UHS-I bus and carry U1 and Class 10 ratings, guaranteeing a minimum write speed of 10 MB/s. Maximum read speed reaches 90 MB/s while maximum write speed reaches 45 MB/s. A protective holder is included for safe transport and organisation.

Suited for Full HD cameras and casual shooters

The cards are designed for devices that support the UHS-I bus, such as digital cameras, DSLRs and camcorders. They handle Full HD video, raw stills and JPEG images reliably. Photographers who need 4K video capture, sustained burst rates above 45 MB/s, or capacities larger than 16 GB per card should consider higher-specification media.

Simple drop-in installation

Insert each card into a compatible SDHC or SDXC slot until it clicks; the built-in write-protect switch prevents accidental erasure. No drivers or formatting tools are required beyond the camera’s own format function. The most common issue is using a legacy reader that cannot address the UHS-I bus, which limits transfer speeds to the older default mode.

Questions about this item

Does my camera need a UHS-I slot to use the 16GB Transcend 300S cards at their rated 90 MB/s read speed?

Yes, the UHS-I bus is required to reach the maximum 90 MB/s read and 45 MB/s write figures; in a non-UHS-I slot the cards will fall back to the host's lower speed class.

Will the Class 10 / U1 rating on these cards still guarantee 10 MB/s minimum write in an older camera that only supports Class 10?

The U1 and Class 10 markings both certify a 10 MB/s sustained write floor, so any device that honours Class 10 will see that guaranteed minimum.

How can I confirm the cards are delivering the advertised 90 MB/s read and 45 MB/s write after I format them?

Run a synthetic benchmark such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader; sequential results should approach 90 MB/s read and 45 MB/s write.
