6 MBps Write Speeds / 125MBps Read Speeds

[Orion83]

I'm new to Unraid and just set up a server with 1 HDD (no parity/no cache). I can read/copy from the server to my windows at speeds of 125MBps over a gigabit connection. However, when I am writing to the server I can only get do 6MBps average on Windows. Looking for some help troubleshooting this. Thanks.

What size files are you writing?  

 

Try a very large single file (like a BluRay ISO or an image of a computer hard drive) and see what speed you get then.

 

Also attach your diagnostics file to a new post in this thread.

Running an iperf test would help narrow the focus.

I've added a parity drive now and I'm fluctuating between 4-10 MBps. Both PC and Server are wired with CAT6 to a gigabit switch. I've attached the diagnostics. OpenSpeedTest from PC shows 1000Mbps download, 200Mbps upload. I've attached the diagnostics zip.

Found this in the syslog:

I have (personally) never seen this situation.   What is the "PC"  that you are talking about--- VM or free standing hardware?

 

Also have a look at the Main tab of the GUI and see if anything else is reading or writing to the array.  You can toggle the display between speed and number of bytes by clicking here:

 

Also check in the "Array Operation" section of the GUI Main tab to see if any array operation is occurring.
