MicroSD Card Quality Significantly Affects Raspberry Pi Performance
When you build your Raspberry Pi projects, you probably just grab whatever microSD card is on the market without thinking about it. However, on a Midwestern Mac, they compared speed between cards and found a big difference in performance.
In testing over a dozen cards, they found that card speed dramatically affected performance, with cheaper cards running significantly slower than well-known brands. The winner when you consider the cost was the Samsung EVO + Class 10 card , which usually costs around $ 10. If you’re interested in testing methods and some other details, head over to the Midwestern Mac. Obviously, this isn’t exactly an exhaustive review, but it does cover the basics well enough considering how cheap microSD cards are these days. It looks like Samsung’s EVO and EVO + cards are the best choice when you’re looking to buy a card for your Pi.
