January 22, 20179 yr I have 2 disks in my array so far Toshiba 3TB HDWD130 WD Red 4TB The toshiba is the first drive in the array and I have noticed my docker containers keep crashing so I did a disk speed test on the toshiba 7200rpm- Timing cached reads: 34150 MB in 2.00 seconds = 17097.55 MB/sec Timing buffered disk reads: 230 MB in 3.02 seconds = 76.27 MB/sec On the WD Red - 5400rpm Timing cached reads: 34654 MB in 2.00 seconds = 17350.52 MB/sec Timing buffered disk reads: 586 MB in 3.01 seconds = 194.81 MB/sec Something doesnt seem right here. SMART reports both drives good. Do you guys think I have a drive going out here? Also I ran these test with nothing running and array stopped Thanks!
January 22, 20179 yr Community Expert I think your measurements are wrong somehow. Perhaps you are confusing Mbits with MBytes.
January 22, 20179 yr Author I copy and pasted straight from hdparm test that unraid faq suggests. hdparm -tT /dev/sda
January 22, 20179 yr Community Expert Even assuming you have confused Mbits with MBytes, your read speeds are impossible with a spinner.
January 22, 20179 yr Author So it looks about right now - diskspeed.sh for UNRAID, version 2.6.3 By John Bartlett. Support board @ limetech: http://goo.gl/ysJeYV /dev/sdb (Disk 1): 155 MB/sec avg /dev/sdc (Disk 2): 124 MB/sec avg Disk 1 is the Toshiba Any ideas where my bottleneck is then? at times sabnzbd will crawl down to 1MB/s and web UI of plex, sonarr, radarr will not refresh etc. And I get sabnzbd stopping every 5 minutes or so. This is a new install

Close your router ports!
January 22, 20179 yr Author weird. Closed ports now.. Funny though that port wasnt open. I need a better firewall
January 22, 20179 yr Funny though that port wasnt open. I need a better firewall Is the server within the DMZ?
January 22, 20179 yr Author No, DMZ is disabled on router. Only port forwarding I had enabled was ftp - port 22 tcp
January 22, 20179 yr Your firewall was working as you configured it. Port 22 is used by ssh, which tallies with your syslog. ftp uses ports 20 and 21, but you really don't want to be exposing unRAID's ftp daemon to the Internet.
