Review on 512GB Micro SD Card (Class 10 High Speed) SD Memory Card/TF Memory Card With SD Card Adapter For Camera by Kevin Woods

I got this for my Raspberry Pi4 and figured I'd risk buying a cheap generic Micro SD card as I haven't used it in a drone or camera and didn't need high speed. Lesson learned. This card is terrible. When I tried to burn images with Etcher or Raspberry Pi Imager they failed. Etcher just completely failed and said it can't see the card anymore. RPi Imager pretended to be successful, but when I booted the Pi from the card it reported all sorts of bad data blocks. Once I was able to load and run a simple 0.8GB RetroPie image on it, but shortly after loading RetroPie it crashed. Marking bad blocks with fsck didn't help either. I ended up getting this Samsung EVO card and everything I tried here worked with this Samsung card - https://amzn.to/3i4fu52 I have the same tasks on a Samsung Evo branded card of the same size and a Sandisk Ultra of the same size, and they worked perfectly every time. No disk errors, no lags or application freezes. So I thought maybe the cheap route would work for me, just using it as a drive with the OS and some apps, but I was seriously wrong. I'm very surprised by all these high ratings (right?), but my experience today has shown that this card is bad news. Don't waste your time if you're serious about data integrity. and your personal time that you spend on it. ;) I would recommend spending a little more on big names like Sandisk and Samsung.
