LAN speed

Hi everybody
i bought one NAS WD my cloud EX4 12 TB, i have a core cisco switch (1 Gb/s) and when i copy paste from my server (having NIC 1 Gb/s) to my NAS (having 1GB/s) i get a low speed of max 5.5 MB/s
i cannot understand why i get such speed 5.5 MB/s ~ 44 Mb/s while i have 1Gb/s infrastructure
??thank you guy for any information
-
And just to confirm, the NAS is connected to the network, and not the USB, correct?

off course, NAS has NIC (1Gb/s) and it is connected to my switch
-
What is the network status light on the NAS?
-
What kind of disks are you reading from/writing to? Granted the should be faster then this but some disk systems will not saturate a 1Gb/s link.
-
where can i get this info ??
-
Ah, I see now it is from your server. That may not be the issue then I thought it was from your desktop.
-
When you look at the status of the NIC on each, do they both indicate that you are connected at 1 Gb?
-
for the server i can see 1Gbs , but for the NAS i do not know where i can see the actual speed of the NIC, all i can see is a dashboard like this :
-
I don't know the cisco commands, but I'm assuming you can run a command on the switch to see what speed each port is currently set to run at.
-
Also, what RAID level did you pick? If you picked RAID 5 for example, the device could be doing some sort of setup across the drives that may have to finish before you'll see full performance (this is only a guess).
-
@Dashrender it is a RAID 10, array of 4 HD, 3TB each
this is what makes me disappointed because i'm supposed to get better performance, i mean the RAID10 include RAID 0 which increase the speed of R/W, but unfortunately i didn't obtain even the normal speed -
You can check by looking at the LEDs on the front of the switch port. If one is a solid green it is 1Gb/s if it is yellow then it is 100Mb/s.

it is blue Sir, all 4 are blue
-
Did the NAS come with the Drives, or did you purchase them separately?
Do you know what model hard drives is in the NAS?

On the Cisco Switch? Where the cables plug in? Not the other side (assuming there are lights on the other side).
-
Oh man... it looks like Solid blue indicates the port is running at 10Mb/s (If I'm reading the right documentation) if the duplex LED is also blue then you are running at half duplex.

Hopefully that's not right - since he did indicate that he checked on the server NIC status and it told him he was running at 1 Gb.

The documentation here PDF jump to Page 125 has all of the network information for this system.
So it's easily confirm-able if this unit is set for Half or Full Duplex, as well as the speed of the NAS NIC.

yeah i'm talking about the NAS LEDs not the switch LEDs,
the switch LEDs are green
