*** Solved: Bad network connection made the difference between 112 MB/s file transfers and 5 MB/s! ***
Hi,
with the minimal setup of a Raspberry Pi 4 with the OMV4 image and an external USB 3.0 HDD, I get very slow transfer speeds.
I have tried and failed clean installation of OMV5 on a current buster image. Then I have found the OMV4 image on reddit and, after much of f***ing around and pure luck, got it to boot and show a web GUI.
Now, I have managed to reformat the drive (6 TB WD external) from NTFS to ext4 and set a shared folder which I can fully access through Windows 10.
I am connected directly to the router via ethernet cable and "ethtool eth0" tells me a speed of 1000 Mb/s. Router is a Fritz!Box 6490.
The USB ports are recognized as USB 3.0 (5000M).
"hdparm" also shows values of 150 MB/s for buffered disk reads.
What am I doing wrong?
