Capacity and use case

This microSDXC card delivers 1TB of storage for Android smartphones, action cameras and drones. It carries UHS-I, U3, V30 and A2 ratings for 4K UHD video capture and fast app loading. The bundle includes a full-size SD adapter for broader device compatibility.

UHS-I bus limits

The UHS-I interface caps sequential reads at 170MB/s and writes at 90MB/s, so sustained throughput cannot exceed those figures. Devices limited to the UHS-I bus will not benefit from faster card specifications, and real-world speeds vary with host hardware and file sizes.

Minimum sustained write

The V30 rating guarantees a minimum sequential write speed of 30MB/s, which is the threshold for uninterrupted 4K UHD recording. Cards without this rating risk dropped frames during high-bitrate capture, making V30 the decisive spec for that workload.

Questions about this item

1TB capacity — is that the right size for my 4K drone footage?

1TB holds roughly 400GB of 4K UHD video at the card's rated V30 sustained write speed, so you can record long sessions without swapping cards.

The box says 170 MB/s read — will I actually see that when offloading to my laptop?

You can reach 170 MB/s read only with a UHS-I card reader that supports the same bus; a slower reader or USB 2.0 port will cap the transfer well below that figure.

UHS-I U3 V30 A2 — what do those ratings mean for real-world recording and app use?

U3 and V30 guarantee a minimum 30 MB/s sequential write for 4K video without dropped frames, while A2 certifies faster random reads and writes for loading Android apps directly from the card.
