If your card is not U3 this doesn’t necessarily mean that it is not up to the job. U3 is pretty new and is a response to ensure that consumers can easily identify those cards with the highest transfer rates suitable for 4K/2K filming.

This can be seen on cards as a number within a bucket/U. UHS sets a minimum transfer of data that the card is capable of in a similar way to the SD speed class. Ultra High Speed 1 – U1 is the same as Class 10 (10MB/s). Just to confuse things a little more there is also an Ultra High Speed (UHS) classification. This can be seen on cards as a number within a circle. Speed Class is a minimum speed based on a worst case scenario test and represents the minimum transfer rate of data that the card is capable of. The Speed Class Rating is the official unit of speed measurement for SD cards. Micro SD cards are roughly the size of a mobile phone sim card and are often supplied with an adaptor to allow them to be used within tech that uses full size SD cards. The GoPro Hero 3 – white, silver, black and the even newer newer GoPro 3+ range use Micro SD Cards. This post also now contains references to the Hero 4 range of cameras.

I have updated this post to ensure that the best cards possible are identified. Hopefully my trial and error over the last few years will point you in the right direction.

The choices of GoPro Hero 3 And 3 Plus micro SD cards is huge. Many ask what is the best SD card for my GoPro camera? The GoPro HD Hero3 and 3 Plus series of cameras support Micro SD cards up to 64GB.

One of the biggest areas that is overlooked when getting a video/camera setup for trips out is the speed of the your SD card.
