Twin-pack microSDXC for Android expansion

This bundle supplies two 64 GB microSDXC cards for a combined 128 GB of removable storage. Each card carries the SanDisk Ultra label and is rated A1 for faster app loading on Android phones and tablets. The UHS-I Class 10 rating guarantees sustained write performance for Full HD video capture. A standard SD adapter is included for use in larger slots.

UHS-I Class 10 with A1 app performance

The decisive specification is the UHS-I U1 Class 10 speed class paired with an A1 rating, which certifies minimum random read and write IOPS for application use. Maximum sequential read reaches 140 MB/s, enabling transfers of up to 1000 photos per minute. Cards without the A1 mark may not sustain the same app responsiveness.

Low heat and silent operation in daily use

Solid-state flash memory produces no audible noise and negligible heat during typical read or write workloads. Power draw is limited to the microSD bus supply, so battery impact on a smartphone or tablet is minimal. The cards operate reliably within the standard temperature range for consumer mobile devices.
