Why Do You Need a Fast SD Card for Your Camera


Let’s take this as an example: You’re recording a high-resolution 4K or even 8K video with your camera, but the microSD card you’re using with it is too slow. In such scenario you may end up facing unexpected hassles like random stopping of video recording or other errors. So, it’s really important that you use a memory card that is compatible with your particular camera model and that it has an adequate speed to ensure smooth and hassle-free video recording.

But what’s an “adequate speed”? To know about it, you should have a basic understanding of the SD Card Speed Class standards. Have a look at the section below.

The microSD cards I’ve presented you today are just perfect for all the action cameras: GoPro, DJI and insta360.

 

SD Card Speed Class Standards


Recording video requires a constant minimum write speed to avoid ‘frame drop’ or video recording errors while you’re recording. A fast SD card ensures a safe storage of your videos and a smooth playback. The SD Association has defined various Speed Class standards. This is mainly useful for camcorders, video recorders and other devices with video recording capabilities.

There are three kinds of SD Card speed indications:

  1. Speed Class: includes Class 2, 4, 6 and 10.
  2. UHS Speed Class: includes UHS Speed Class 1 (U1) and UHS Speed Class 3 (U3).
  3. Video Speed Class: includes V6, V10, V30, V60 and V90.

These speed classes are labelled on the front side of each SD memory card. The labelling is in the form of little numbers with a circle, a U shape, or a V shape. The manufacturers use these “classes” to determine the speed of the memory card.

Word of Advice


While speed is an important aspect while choosing a microSD card for your camera, it’s not always true that the fastest card is necessarily the best card for your needs. There are other factors that matter too, which may include price, availability and compatibility with your camera model. So, before buying any memory card, I’d suggest you to double check the compatibility of your camera with any SD card that you may want to buy.
