I've owned a Nintendo Switch now for almost six years and never thought to upgrade the internal storage available in my system - until now that is. That's because the Amazon Prime Day 2023 deals have the cheapest rates on SD cards specifically made for the console which are hard to argue against for the price-per-gigabyte. 

The best SD cards for Switch are easily one of the most important accessories for the Nintendo Switch, however, they can run pricey depending on the capacity. While I enjoy the console, I have found the 32GB storage filling up as I've picked it up again recently to enjoy some of the best Nintendo Switch games. However, this plight can easily be overcome with just a fistful of dollars (or pounds) as the Prime Day Nintendo Switch deals are demonstrating. 

Those based in the US have still got a handful of hours until Amazon Prime Day 2023 concludes, though, shoppers in the UK are rapidly running out of time. It's likely that some of these SD card deals will be available once the clock strikes, but it's not guaranteed. Below, you'll find my top picks before time runs out. We're also bringing you all the best Prime Day gaming deals for more on Nintendo Switch software.
