Explaining SD Cards: 2025 Update

SD cards explained -- including their capacity types, speed classes, application classes, and bus interfaces. Video covers the latest SDUC cards and SD Express, and also includes comparative tests of UHS-I, UHS-II and SanDisk Quickflow UHS-I cards.

As noted in the video, I personally always purchase SanDisk SD and microSD cards, and usually the Extreme PRO models. The cards I currently use are available from Amazon as follows:

256GB SanDisk Extreme Pro UHS-I card:
