SanDisk Extreme 32GB microSDHC V30 U3 UHS-I

This 32GB microSDHC card carries V30 and U3 speed ratings for sustained 4K Ultra HD and Full HD video capture. Read speeds reach up to 100MB/s and write speeds up to 60MB/s. It is built temperature proof, water proof, shock proof and X-ray proof for action cameras and drones. The Extreme series targets creators who need reliable performance in harsh environments.

Upgrading from slower Class 10 or U1 cards

Moving to V30 eliminates frame drops during high-bitrate 4K recording that lesser cards cannot sustain. The jump is worth it when your device writes at or near 30MB/s continuous and you need guaranteed minimum throughput. Cards rated only for lower video speed classes will throttle and risk corrupted footage under the same load.

Verify your device supports microSDHC and UHS-I

Check that the host accepts microSDHC capacity and can utilise UHS-I bus speeds for the rated transfer rates. Confirm the card slot is not limited to standard SDHC speeds which would cap performance below the advertised 100MB/s read. No adapter is included so ensure your reader or device takes microSD directly.

Questions about this item

Does this 32 GB microSDHC card need an adapter to fit a full-size SD slot?

The card is microSDHC size; the listed option says no adapter is included, so you must supply your own SD adapter for full-size slots.

What is the correct way to insert the card so the UHS-I interface runs at up to 100 MB/s read?

Align the gold contacts facing down and push gently until it clicks; forcing it backwards can bend the contact pins and drop the link to a lower speed.

When should I replace this V30 card to keep 4K video recording reliable?

Replace it if write speeds fall below 30 MB/s sustained, if the card reports errors during 4K capture, or after heavy daily use over several years.
