32GB microSDHC card for portable devices

This SanDisk Ultra microSDHC card delivers 32GB of removable storage in the microSD form factor. It is built for smartphones, action cameras, drones and other compact gadgets that rely on a small, durable memory card. The UHS-I interface provides broad compatibility with current and legacy host devices. No adapter is included in the package.

Class 10 rating guarantees 10 MB/s minimum write

The card carries a Class 10 speed rating, which means sustained sequential write performance of at least 10 MB per second. This threshold is the deciding factor for recording Full HD video without dropped frames. Host devices that require a Class 10 or U1 card will recognise this specification and enable their highest-quality recording modes.

100 MB/s read speed supports fast offloads

Rated read throughput reaches 100 MB per second, allowing quick transfer of photos and footage to a computer or backup drive. Write speed is also specified at 100 MB per second, so sustained captures benefit from the same ceiling. Performance holds steady during long recording sessions because the card has no moving parts and no thermal throttling mechanism.

Questions about this item

What does the 100MB/s read speed mean for actual file transfers?

The 100MB/s read rating is the maximum sequential speed the card can sustain when pulling large files like photos or video clips off the card in a compatible device.

What does the UHS-I interface limit in practice?

UHS-I sets the bus timing for the card, and this model runs at the 100MB/s read and 100MB/s write speeds the card is rated for.

What slot size and format does this 32GB microSDHC card need?

It fits any microSDHC or microSDXC slot; older microSD-only slots that pre-date the HC standard will not accept this 32GB capacity.
