32 GB microSDHC U3 V30 A1 card

This SanDisk Extreme Pro microSDHC card provides 32 GB of storage with UHS-I Class 10 performance. Rated U3 and V30, it sustains write speeds up to 90 MB/s and read speeds up to 100 MB/s for Full HD and 4K video capture. The A1 rating supports faster app loading on compatible devices. A full-size SD adapter is included for use in standard card slots.

Action cameras, drones and Android devices

The card suits users who need reliable U3/V30 sustained write performance for 4K recording or burst photography on UHS-I hosts. Buyers requiring UHS-II bus speeds or higher video speed classes for professional cinema bitrates should consider a different tier. Devices limited to microSDHC capacity will accept this 32 GB card; those needing 64 GB or 128 GB can choose the larger Extreme Pro options.

U3 and V30 sustained write rating

The U3 and V30 markings guarantee a minimum sequential write of 30 MB/s, which is the decisive spec for 4K video workflows on UHS-I hardware. If your device or workflow demands a higher guaranteed minimum write speed, this card will not meet that requirement.

Questions about this item

What does the 100MB/s read speed mean when I put the card in my camera or phone?

The 100MB/s figure is the maximum sequential read rate under test conditions; real-world transfer speeds depend on the host device's UHS-I implementation and file sizes.

How does the UHS-I interface affect the 90MB/s write rating?

The card uses a UHS-I bus, so the 90MB/s write speed is the peak the interface can sustain; actual write throughput will match the slowest link in the chain.

Will the included adapter let me use this microSDHC card in a full-size SD slot?

Yes, the supplied adapter converts the microSDHC form factor to standard SD dimensions for use in full-size card readers or cameras.
