Two-card microSDXC kit

This SanDisk kit contains two microSDXC cards, each offering 128GB of storage. They are intended for phones, action cameras, drones or other portable devices that accept the microSDXC format. The Class 10 rating guarantees a minimum sustained write speed of 10MB/s for Full HD video recording.

Simple slot insertion

Installation only requires pushing each card into the device’s microSD slot until it clicks. The main issue is inserting a card into a host that only supports the older microSD or microSDHC standards, which cannot address 128GB capacities. No drivers or formatting tools are needed on compatible hardware.

microSDXC capacity ceiling

The microSDXC standard used here tops out at 512GB, so these 128GB cards sit well within the format’s maximum. Devices limited to microSDHC will not recognise cards larger than 32GB, and legacy microSD hosts stop at 2GB. Adapters allow physical fit in full-size SD slots but do not override the host’s format limit.

Questions about this item

How can I confirm both 128GB microSDXC cards are working at Class 10 speed after installation?

Insert each card into your device and run a write-speed test; sustained writes at or above 10 MB/s confirm Class 10 performance.

What comes in the pack and do I need to buy adapters separately?

The pack contains two 128GB microSDXC cards; standard SD adapters are not included and must be purchased separately if your device uses full-size SD slots.

Which capacity should I choose between the 128GB microSDXC and the smaller microSDHC sizes?

Choose the 128GB microSDXC version if your device supports SDXC (64GB to 512GB); older devices limited to SDHC only accept up to 32GB.
