Ideal for compact cameras

The SanDisk SDSDUNC-128G-GN6IN is a 128GB Ultra SDXC UHS-I Class 10 memory card built for compact to mid-range point-and-shoot cameras. It stores large collections of photos and Full HD video while delivering read speeds up to 80MB/s for quick transfers to a computer.

Not for high-end video workflows

Photographers needing 4K capture or sustained write speeds beyond Class 10 minimums should look elsewhere. The card is also unsuitable for devices that only accept the older SDHC standard, as its 128GB capacity exceeds that format limit.

128GB SDXC capacity decides fit

The Secure Digital Extended Capacity format is the single specification that determines compatibility; the host device must explicitly support SDXC cards to recognise the full 128GB storage space.

Questions about this item

How can I confirm the card is delivering its rated Class 10 performance after first use?

Record a short Full HD 1080p clip; smooth playback without dropped frames shows the sustained write speed meets the Class 10 spec.

What comes in the package and do I need to buy a reader separately?

The box contains only the 128GB Ultra SDXC card; a compatible SD card reader or camera slot is required to transfer files.

Which capacity should I choose for a compact camera that shoots Full HD video?

The 128GB version holds many hours of 1080p footage and matches the 80MB/s read speed quoted for the Ultra series.
