IN CAR RECORDING CAMERAS

[Dead Eye]

Note that Class 10 only requires the card to perform at a minimum Read / Write speed of 10 MB/s and that you can get varying cards even at this classification.

The card I linked to is UHS-I (Ultra High Speed I) rated and performs at up to 45 MB/s despite the minimum requirement still being 10 MB/s. Take all of this in to account when buying a "high performance" SD Card before you get caught out like a few others who reviewed probably did.
