2TB microSDXC UHS-I Card

This SanDisk Extreme microSDXC card provides 2TB of storage with UHS-I interface speeds. It carries U3, V30, Class 10 and A2 ratings for sustained write performance. Read speeds reach up to 240MB/s while write speeds reach up to 140MB/s.

For action cameras and Android devices

The card suits users capturing 4K UHD video or running apps directly from the card thanks to A2 performance. It is not suited for devices that only support UHS-II or higher video speed classes for sustained cinema bitrates.

UHS-I 240MB/s read speed

The single specification that decides fit is the UHS-I interface with 240MB/s maximum read speed. Host devices limited to slower UHS-I implementations or older speed classes will not achieve the rated transfer rates.

The card is rated V30 and U3, guaranteeing a minimum 30MB/s sustained write speed for 4K UHD video, while the 140MB/s figure is a peak burst rate.

How hot or loud does the card get during all-day shooting?

As a solid-state memory card it has no moving parts, produces no noise, and its shock-, temperature-, water- and X-ray-proof design handles extended use without overheating.

Which reader do I need to reach the 240MB/s read speed?

The SanDisk Professional PRO-READER SD and microSD is required to achieve the stated 240MB/s read performance; it is sold separately.
