Capacity and speed class

This SanDisk Extreme SDXC card provides 64 GB of storage rated for UHS-I U3 and Video Speed Class V30. It targets photographers and videographers who need reliable continuous write performance for 4K capture. The card carries a maximum read speed of 170 MB/s and a write speed of 80 MB/s.

Sustained write behaviour

The V30 rating guarantees a minimum sequential write speed of 30 MB/s during extended recording sessions. This prevents frame drops when the camera buffer fills during long 4K video takes. The UHS-I interface maintains that floor without relying on short burst peaks.

Upgrade path and fit

The card replaces older Class 10 or U1 media that cannot sustain 30 MB/s writes. The jump is worth it when moving to 4K workflows or high-bitrate codecs that exceed slower cards. It is not for users who need UHS-II speeds or capacities above 64 GB.

Questions about this item

Does the 170 MB/s read speed generate noticeable heat during long video recordings?

The card is rated for 170 MB/s read and 80 MB/s write with UHS-I U3 V30 class; it runs within normal SD card thermal limits during sustained capture.

What host device slot is required to reach the 80 MB/s write rate?

A UHS-I SDXC slot that supports U3 / V30 speeds is needed; older UHS-I or Class 10 only slots will fall back to lower throughput.

Will this 64 GB card work reliably in a camera that only takes SDHC cards?

The card follows the SDXC specification; devices limited to SDHC (32 GB maximum) cannot address its 64 GB capacity.
