SMB transfer very slow !

  • Hi,

    I am using the latest LibreELEC version with a Raspberry Pi 4 2GB.

    I have an external USB hard drive connected to the USB 3.0 port of the Raspberry Pi.

    When I try to copy a file from my computer to the external hard drive over the network using SMB, the transfer speed is very slow (around 2 Mo/s).

    I have tried other devices with different file systems (NTFS, FAT32, exFAT), but I encounter the same problem, whether using Wi-Fi or a wired connection.

    Any solutions to fix this?

  • Have you tried to assess the pure network speed using tools like iperf3?

    Currently I'm not using a RPi+USB+SMB, but I remember the RPi was a bit picky about the power supply, so you may want to check the logs about any related error or warning messages. Does the external HDD have an own power supply?
