microSD Card Write speed goes down to 512 KB/s
Hello,
I have a problem when writing to a Sandisk Ultra 128 GB microSD card that I use in my music player (Ibasso DX50).
When I copy music files to the card, for the first 4 or 5 files, the throughput is OK (between 4 and 10 MB/s), but systematically after a few files, the speed goes down to 512 KB/s.
I have the same problem using this card on another PC, so I assume the problem is with the SD card.
I formatted the card to FAT32, because I had problems with the native SD card format.
I did not notice the problem at the beginning, when the card was almost empty, but now the card is almost full, and I think the problem occurs more and more easily.
Thanks for helping.
