Capacity and speed class

This SanDisk Extreme SDXC card provides 512GB of storage with UHS-I interface, U3 and V30 ratings. Read speeds reach up to 230MB/s and write speeds up to 160MB/s. It is built for photographers and videographers capturing high-resolution stills and 4K UHD video.

Who this suits and who it does not

The card suits creators shooting 4K UHD and using sequential burst modes who want faster offloads via SanDisk QuickFlow Technology. It is not for users who require sustained write performance above the V30 guarantee for higher-bitrate cinema workflows.

Deciding specification

The V30 video speed class certifies a minimum sustained write of 30MB/s, which determines whether the card can reliably record your chosen 4K bitrate without dropped frames.

Questions about this item

How long can the card sustain 160 MB/s writes before the speed drops?

The card is rated U3 and V30, guaranteeing a minimum sustained write speed of 30 MB/s; the 160 MB/s figure is a peak rate.

Does the card run hot or draw extra power during all-day 4K recording?

SD cards have no active cooling and draw very little power; sustained 4K capture at U3/V30 speeds stays within normal operating temperature.

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

A UHS-I reader that supports the 230 MB/s bus mode is required; the SanDisk Professional PRO-READER SD and microSD is one example.
