So much so that you might get confused as to which one is the best option for your needs. That’s why I’ve come up with this post,

In this article, you’ll discover some of the best SD Cards for 4K video recording.

 

Why Do You Need a Fast SD Card for 4K Videos?


When you’re recording a video in high 4K resolution, you’ll need an SD card that’s fast enough. That’s because if the SD card you’re using with it is too slow, you may end up facing unexpected hassles like the random stopping of video recording or other errors.

Therefore, it’s really important that you use a memory card that’s compatible with your camera and has an adequate speed for uninterrupted 4K video recording. An SD card that’s fast enough ensures safe storage of your videos and smooth playback.

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.

Have a look at the graphic below to understand the kind of speeds offered by each speed class.

So, for uninterrupted 4K video recording, you’ll need an SD card with at least a V60 video speed class.

Final Words: Which SD Card to Choose?


Speed is definitely an important aspect while choosing an SD card for your camera. However, please note that it’s not necessary that the fastest card would the best card for your needs too. You need to consider various other factors, like brand, price, availability, and compatibility with your camera.

Therefore, before making a buying decision, you should always double-check whether your camera is compatible with the SD card that you’ve chosen. If your 4K camera is UHS-II compatible, then the best option for you is the Lexar Professional 1800x Memory Card. It’s super fast as well as reliable.

However, in case your camera is only UHS-I compatible, then you’ll not really get any speed benefits with the faster UHS-II cards. In such a case, the SanDisk Extreme PRO Memory Card is a perfect choice. I’ve personally used this card is found it to be highly dependable.
