@setq Thanks for the update
@5ft24 Didn’t know that tanks! I kinda new to all of this stuff. Apperently there is someone else having troubles with the transfer speed in this post.
I tried
with the result of 110 MB/sec for all four disks. I’m using an ethernet cable on my server and the computer which is transferring data on it. Has it to do with the bandwidth of my provider? Or is there a way to find the bottleneck?
