I mainly copy my files (videos) to my Unraid by wifi. I usually have speed around 8-10MB/sec...not bad over wifi

I wanted to verify the speeds out of my desktop, wired (gigabit network)

All my tests were done by copy/paste a 1,4Gb file between my desktop and the server, with Windows 7 explorer

1st test: read and write around 11MB/sec.............hurghhh!!! I guess i have something wrong in my cabling

2nd test: I plugged my desktop directly into my router, were the server is already hooked up. Read speed @ ~35MB/sec and write speed @ ~26MB/sec

3rd test: server and desktop plugged on a gigabit switch after the router - approximately the same speeds

4th test: with Teracopy - no improvement in the write speed, but read speed is slower (~28MB/sec vs 35MB/sec)

So I think I'm happy. My next test will be with a cache drive

 

Are those speeds from test 2 and 3 normal speeds?

Is there something to do to have higher speeds?

 

All my drives are green drives, my main router is a Dlink DIR655 and the gigabit switch is a Trendnet green 5 ports

 

Thanks

The write speeds are fine in tests 2 & 3 (depending on just where on the disk you're writing, you'll see between the high 20's and mid-30's for green drives ... a bit faster with newer 1TB/platter units).

 

But the read speeds seem a bit low -- I'd expect at least double that.  This could mean you're writing the data to a slow drive; or you could have a bad Ethernet cable.

 

The speeds in test #1 indicate the network is working at 100Mb ... most likely this is either a bad Ethernet cable or a bad port on your router or switch.

 

By the way, I've found that TeraCopy tends to under-report the speeds, so I wouldn't worry about the somewhat slower speed it's reporting.

I will try with different cables. I could even try with another router (I have a spare DIR655)

However, a bad cable or port would affect both Read AND Write speeds, don't you think?

Trying rebooting the router and all of the switches.  I have found that these devices tend to get 'corrupted' if they run for all periods of time without a reboot.  (Kinda like windows 95  )

Read and write speeds can be effected independently by a bad cable or port.
