Questions about this item

Which card reader do I need to reach the 230 MB/s read speed?

A UHS-I reader capable of 230 MB/s is required; pairing with the SanDisk Professional PRO-READER SD and microSD enables the maximum transfer rate.

Will this 128 GB card work in my older camera that only supports SDHC?

No, SDXC cards are not compatible with SDHC-only devices; the camera must explicitly support SDXC capacity.

How can I verify the card is delivering the rated 120 MB/s write speed during 4K recording?

The camera should show no dropped frames or buffer stalls when recording 4K UHD at the card's U3 and V30 sustained write rating.
