>Description:
i tried to copy files via usb 2.0 to my usb 2.0 mobil rack, but with fat32 file system the performance was terrible.. ~1M/s
fat32 is important to me, because of windows compatibility.
i checked the performance with ufs fs, it had 10M/s peak, which is bad too. However i still need fat32 mainly.
>How-To-Repeat:
use usb 2.0 mobil rack with a fast hdd and ehci driver on 4.10 or 5.2 rls
