here it is. tower-diagnostics-20170923-1505.zip

thanks to all helping me. next problem was to download the zip file in diagnostics. firefox blocking it - but MS edge is working. what info of the log file you need ? i will post instandly. thanks in advance

ok thats clear with cache and ram. but we are talking about sata 3 wd black - its a laugh for that hdds to write that speed ! may be i didn´t got it clear to understand the leak in writing speed.

thanks - very good. I did modification without a restart. Is one necessary ? this at least improved performance from 10 to about 23-26 MB/s. I´m not that familar with Linux systems. What I absolutly don´t get is that reduce in speed after that 30 secs. Is it depending on the parity disk ? I had a xpnology running on the machine before and would like to change OS because of weak support of the cpu by 2 Cores. Ok, it was a JBOD System without any array and parity drive. But never would have thought about that difference in speed ! And sorry, english is not my mother language and every explanation has to be read twice. There also could be a few misspellings - please be patient. btw: nice forum and i feel home after that only 5 postings

nic is about 1gb and what is turbo write and were can i find that option ?

hi, no changes at all as i expected. and option is dangerous if you losing power - all data go to nirwana. its still copying with 10 mb/s - no improvement.

I absolutly don´t understand how it could work perfect on 112 MB starting with and then dropping to unacceptable 10 MB/sec.

Hi thanks for short reply, checked it in bios - its disabled
