Review on 💾 512GB V60 SD UHS-II Memory Card by MKING Digital - Up to 250 MB/s Read Speed and 130MB/s Write Speed, Perfect for Professional Vloggers, Filmmakers, Photographers & Content Curators by Andrea Joint

This was the second of those big 256GB SD drives I was rejected for. Both are the same during the initial installation, regardless of whether it's in the phone or the adapter has such promises, how can you see the whole room. However, once you try to drop files on it, the speed drops to 19G. Files are no longer saved undamaged. No Windows check disk can fix it, nothing seems to fix it. The first disk I bought behaved like this, then it became unrecognizable and went into the trash. Don't buy, you will find the price is too good to be true.
