Capacity and classification

This Patriot Memory microSDXC card provides 64 GB of removable storage and is rated Class 10, U1 and UHS-I. It targets smartphone, tablet, action-camera and drone owners who need dependable full-HD video capture.

UHS-I bus limits

The UHS-I interface caps sequential throughput, so maximum read speed reaches 100 MB/s while write speed tops out at 30 MB/s. Sustained write performance is guaranteed at 10 MB/s, which meets the minimum for uninterrupted 1080p recording.

Speed class decides suitability

The U1 rating is the single specification that determines whether this card matches a device’s requirements. If the host demands a higher sustained write tier such as U3 or V30, this card will not satisfy that need.

Questions about this item

Is the 64GB version the right choice or should I consider the 128GB capacity?

The 64GB card suits full HD video and thousands of photos; the 128GB option simply doubles that space for longer sessions.

The box says 100MB/s read but the title mentions 80MB/s — what will I actually see in my camera?

The card is rated for up to 100MB/s read; 80MB/s is a typical real-world figure, and sustained write reaches 30MB/s.

Does the UHS-I U1 interface limit 4K recording on my drone?

UHS-I U1 guarantees a minimum 10MB/s sustained write, which meets full HD needs but is below the typical 30MB/s required for 4K.
