Take Tidal out of the picture. Get list of files and copy to both internal memory and then your MicroSD card and time how long it takes to do both tasks using same files. Then put Tidal in picture and time the operation to internal memory and then to microSD. You can use Files app to do this taking a PC out of the picture as well. To have off-line storage on internal memory should not be a problem as we now have 256GB vs 128GB. I don't know if there is any difference in SQ if using industrial MicroSD like Swissbit vs internal memory. Swissbit has insanely high TBW rating.So why does an 8 year old LG V20 download to the same SD card at the same speed I get on a DX340 with UFS internal storage? I don't think the problem is with tidal.
