What this card is and who it suits

The SanDisk Extreme microSDHC card delivers 32 GB of storage with UHS-I Class 10 performance. Sequential read speeds reach 100 MB/s and write speeds hit 100.0 MB/s. It carries A1 and Video Class V30 ratings for app loading and sustained video capture. The bundled microSDHC-to-SD adapter lets you use it in full-size SD slots.

Check your device before ordering

Confirm your host device supports the microSDHC form factor and the UHS-I bus interface. The card requires UHS-I U3 capability to sustain the rated write speed for V30 video recording. Older hardware limited to standard SDHC or lower speed classes will fall back to slower transfer rates. The adapter only changes physical size, not the electrical interface.

How it fits into your workflow

Insert the card directly into a microSD slot or use the included adapter for standard SD readers and cameras. The 32 GB capacity suits Full HD and 4K footage at V30 bitrates without frequent offloads. A1 rating accelerates app launch times on compatible phones and tablets. It frees internal storage for system files while keeping media portable.

Questions about this item

Does the 32 GB microSDHC card come with an adapter or do I need to buy one separately?

The package includes a microSDHC to SD adapter so you can use the card in full-size SD slots without an extra purchase.

Should I choose this 32 GB UHS-I U3 V30 card or a larger capacity for 4K video?

This 32 GB card meets U3 and V30 ratings for sustained 30 MB/s write speeds; pick a higher capacity only if you need more total recording time.

Will the advertised 100 MB/s read speed be reached in my camera or drone?

The 100 MB/s figure is the maximum sequential read speed; actual throughput depends on the host device's UHS-I implementation and file system overhead.
