64 GB microSDXC for 4K capture

The SanDisk Extreme microSDXC card provides 64 GB of storage for Android smartphones, action cameras and drones. It records 4K UHD and full HD video without skipping frames and stores high-resolution photos. The A2 rating delivers fast application performance for a responsive smartphone experience.

160 MB/s read and 90 MB/s write headroom

Sequential read speeds reach 160 MB/s to move large 4K files off the card quickly. Write speeds of 90 MB/s sustain continuous 4K UHD recording and fast-action photo bursts. The 64 GB capacity fills during extended 4K sessions; higher-capacity variants up to 400 GB exist in the same range for longer shoots.

UHS-I interface fits existing slots

The card uses the UHS-I bus, so it works in current microSDXC slots without adapter changes. It frees up internal phone storage by offloading apps and media directly to the card. No extra power or firmware steps are required beyond a compatible host device.

Questions about this item

Will the 160 MB/s read speed work with my older UHS-I card reader?

Yes, the card uses the UHS-I interface so it will function in older readers, though the 160 MB/s maximum read speed requires a reader that supports the same UHS-I mode.

How can I verify the A2 rating is delivering faster app loading on my phone?

Move apps to the card in Android settings and compare launch times; the A2 specification means sustained random read and write performance is optimised for application workloads.

Does the package include a full-size SD adapter for my laptop slot?

The supplied contents list only the 64 GB microSDXC card itself; a microSD-to-SD adapter is not included and must be purchased separately if required.
