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.
