  • Lost footage or frames,
  • Freeze your GoPro or your camera


Can UHS-II Cards Be Used in the GoPro HERO9 Black?

Other Memory Card Classes for Gopro Hero 9 to note

The V-class is a new Speed Rating category for SD cards that are meant to perform at the Speed suitable for 4K / 5K video recording.

  • Cards with a minimum sequential write speed of 60MB/sec are classified as V60.
  • V30 is assigned to cards that have a minimum sequential write speed of 30MB/sec. These are designed to Support 1080fps Full HD Recording

The U3 Cards Supports 4K video capturing at a sustained rate of 30MB/s. The U3 class is similar to the more recent V30 class.

  • With a minimum sequential write speed of 10 MB/sec, U1 is designed to accommodate real-time broadcasts and HD video (720p and 1080p). This is similar to the newer V10 class.

Class 10 is meant to handle 1080p recording with a minimum Sequential write speed of 10 MB/sec (although not at all framerates).

Classes 2, 4, and 6 are the most common Card available to buy for your GoPro Hero9, they are designed with a serial write speed of 2 MB/sec.

With a minimum serial write speed of 4 MB/s and 6 MB/s, respectively, Classes 4 and 6 are designed to support 720p and 1080p video (although not all framerates).

Finally, you might have noticed the speed ratings A1 starting to appear on some of the newer cards. That’s a different type of speed rating geared toward apps. Devices that run apps, like smartphones and gaming devices, don’t send a long stream of continuous data but rather lots of small chunks of data.


Finally, you may have noticed that some of the newest cards are starting to have the A1 speed ratings. That’s a separate kind of app-specific speed rating. App-running devices, such as smartphones and game consoles, do not send a continuous stream of data, but rather a large number of little bits.

As a result, they require cards with high random write rates. And that’s where the A ratings come in: they’re used to identify micro SD cards that are appropriate for use on mobile devices. This class Rating should not affect your choice of an SD card for your GoPro.
