Hi when i try to copy large folders with many files (game folders) into my usb stick it starts with 50-60 MB/s and then it drops to 0 then again 50-60 then to 0 again . Is this normal? I tryed various methods like formating my drive to NTFS and changing to better performance w/o write catching cause it didnt let me select it . Also turned on/off legacy support from bios and 2.0 support nothing changed .
