256 GB microSDXC for 4K capture

This 256 GB microSDXC card targets action-camera owners, drone pilots and Nintendo Switch players who need reliable ultra-high-definition recording. UHS-I Class 10, U3 and V30 ratings guarantee sustained write performance for 4K video. A2 qualification speeds up app loading on smartphones and tablets.

V30 sustained write for 4K video

The decisive spec is the V30 speed class, which certifies a minimum sequential write of 30 MB/s. That threshold is what allows uninterrupted 4K capture on GoPro, DJI and similar devices. Read speeds reach 100 MB/s and write speeds reach 60 MB/s for faster offload and app performance.

Best for action cameras and Switch expansion

Buyers who need guaranteed 4K recording on action cams, drones or a Nintendo Switch will find the V30 rating and A2 performance a direct match. Users requiring higher sustained write speeds for 8K or professional cinema workflows should look at something else.

Perguntas sobre este artigo

How does the 100 MB/s read speed translate to actual use in a device?

The card delivers sequential read performance up to 100 MB/s, which lets you offload 4K footage or large game files to a computer quickly when the host slot can sustain that rate.

What does the UHS-I and V30 rating mean for real-world write limits?

V30 guarantees a minimum sustained write of 30 MB/s, so 4K video recording won't drop frames; the UHS-I interface supports the card's rated 60 MB/s peak write.

Will this 256GB microSDXC card fit my action camera or Switch slot?

Yes, it uses the standard microSD form factor, so it fits any device with a microSDXC slot, including GoPro, DJI drones and Nintendo Switch.
