I thought that this might be because of the power supply, but it does not explain why everything works on a fresh installation.

Here is my log from old system:

I do not notice any difference in kernel logs.
My power supply unit for this nettop has 19V and 3.42A, what gives about 65W. I think it should be enought for power one external disk.

Thanks for replay,

My usb hhd must work as USB 3.0 beacause read speed is correct:

Code

root@media:~# hdparm -t /dev/sdb1


/dev/sdb1:


 Timing buffered disk reads: 392 MB in  3.00 seconds = 130.58 MB/sec

Its not possible to reach 130MB/s on usb 2.0, I think. Only write speed is so low

My dmesq and kernel log do not indicate anything strange.
When I boot fresh install OMV my write speed on this HDD back to stable 100MB/s+.

Hi since few days my disk slowed down. When I install ovm about week ago my disk works perfect and got transfer write/read about 110MB/s. Now I get not even half this value. The write values have dropped to about 25MB/s and read is about 80-100MB/s. Im tested this by dd command:

Edit Source Code

root@media:/srv/dev-disk-by-label-Segate# dd if=/dev/zero of=pk count=1 bs=400M
419430400 bajtów (419 MB, 400 MiB), 19,7161 s, 21,3 MB/s

What is strange when I installed the fresh system on the second pendrive everything has returned to normal and the write speed is again within 110 MB/s.
It looks like the speed of writing was limited somewhere in the system, but I dont know where. Im trying set max performance in disk options, but it did not bring any results.
I would not like to re-install my system once a week, because that's not the point.

My hardware Nettop nt-i1550:
intel atom d2700 2/4 2.13 GHz
4Gb DDR3
Sagate Expansion 1TB USB 3.0
16GB Pendrive USB 2.0 for system (with installed flash memory plugin)

I hope someone can help me .
Best regards, mix091.
