The impression is that inside it is some kind of controller that erases memory in huge blocks, which greatly slows down the work. In the system, it is defined as an SD card + card reader. I bought it for a media player to immediately download torrents to it, but attempts to use it in this way only hang the system. Now I'm trying to adapt it at least for backups, but it would be better if I bought an external hard drive with that money.
