Capacity and video class

The SanDisk Extreme microSDXC card delivers 2TB of storage for devices that accept the UHS-I interface. It is aimed at creators who capture 5K point-of-view footage or 4K UHD video and need sustained write performance rated at U3 and V30 speed classes.

Form factor and daily handling

The microSDXC form factor fits action cameras, drones and compatible handheld recorders without an adapter. Rated read speeds reach 240MB/s and write speeds reach 140MB/s, so offloading large clips to a workstation is quick when paired with a suitable reader.

Thermals and power in use

The card operates within the standard UHS-I power envelope and has no moving parts, so it runs silently and generates minimal heat during continuous recording. RescuePRO Deluxe recovery software is included free for one year to restore accidentally deleted files.
