Review on 💾 Bundle of PNY 16GB Performance Class 4 MicroSD Flash Memory Cards (5-Pack, P-SDU16G4X5-MP) by Jeff Hill

One of the SD cards didn't even come out of the box. Most others have dozens of bad sectors that need to be repaired before they can be used. They are fundamentally unsuitable for this purpose and should not be entrusted to you with your data. Not at all. When trying to install a new operating system on my computer using one of them, my computer got locked due to bad sectors. Don't make my mistake. It's not worth the tiny fraction of the savings you get.
