Video Description

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: Amazon US: https://amzn.to/40jtdv7 Amazon UK: https://amzn.to/3DEELjP 64GB SanDisk Extreme PRO UHS-II card; Amazon US: https://amzn.to/4a6Of3l Amazon UK: https://amzn.to/3Pn2Ga1 64GB SanDisk Extreme PRO micro UHS-I card: Amazon US: https://amzn.to/3W6HclL Amazon UK: https://amzn.to/4fQ9Pui You can also find the above cards, and well as other products that I use, on the ExplainingComputers Amazon storefronts: EC Amazon US: https://www.amazon.com/shop/explainingcomputers EC Amazon UK: https://www.amazon.co.uk/shop/explainingcomputers Please note that the above are affiliate links, and that as Amazon Associate I earn a commission from any qualifying purchases.
