Sustained write performance

The card delivers up to 30 MB/s sequential write and up to 100 MB/s read, allowing long recording sessions without dropped frames. The V10 video speed class ensures the minimum write threshold is maintained across the entire 64 GB capacity during extended use.

Questions about this item

How much heat or power does the 64GB PRO Endurance card draw during continuous all-day recording?

The card operates within standard microSD power limits; its UHS-I interface and V10 rating are designed for sustained 30 MB/s writes without thermal throttling in typical dash-cam or security-camera enclosures.

What host device or adapter must I already own for this MB-MJ64KA/AM to work?

You need a device with a microSDXC slot that supports UHS-I speeds — such as a dash cam, action camera, drone or a USB microSD card reader — to reach the rated 100 MB/s read and 30 MB/s write performance.

Will this V10 card slow down when used alongside older Class 10 equipment in the same workflow?

The card maintains its 30 MB/s sustained write speed regardless of other media; older Class 10 devices simply operate at their own lower ceiling while this card runs at its rated U1/V10 level.
