One of the biggest areas that is overlooked when getting a video/camera setup for trips out is the speed of the your SD or Micro SD card. Now this doesn’t matter if your camera is a GoPro, Contour, Garmin, Sony or whatever because without a good memory card you may struggle to capture the video footage you want.
As cameras have become more capable the need for faster cards with greater capacity has become more important.
SD Speed Class
The Speed Class Rating is the official unit of speed measurement for all SD cards, including both full and micro sized versions. 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.
