64 GB microSDXC for Android and cameras

This SanDisk Ultra GO card adds 64 GB of storage to Android smartphones, tablets and digital cameras. The UHS-I interface delivers read speeds up to 140 MB/s. An A1 rating helps installed apps and games load more quickly. A full-size SD adapter is included for use in larger slots.

Sustained write performance for Full HD capture

The V10 and Class 10 ratings guarantee a minimum sequential write speed of 10 MB/s. This steady throughput keeps Full HD video recording smooth without dropped frames. NAND flash construction provides durability for repeated write cycles. The card maintains this pace during long recording sessions rather than only in short bursts.

Step up from slower or smaller cards

Replacing a card rated below Class 10 or V10 removes the bottleneck that causes stuttering video and sluggish app launches. The jump is worthwhile when your device supports UHS-I and you need reliable Full HD recording or faster app loading. Devices limited to older speed classes will not benefit from the higher read ceiling.

Questions about this item

Does the 140 MB/s read speed mean the card runs hot or draws extra power during all-day recording?

The card is passive with no moving parts; its UHS-I interface and NAND flash draw minimal current and produce negligible heat even during continuous Full HD capture.

My phone only has a full-size SD slot — what else do I need to use this microSDXC card?

The package includes a microSD-to-SD adapter so you can insert the 64 GB card directly into any standard SDXC slot.

Will the A1 rating and UHS-I speeds work properly in my older camera that only supports Class 10?

Yes, the card is backward compatible; it will operate at Class 10 / V10 speeds in legacy devices while still providing the 64 GB capacity.
