Why are the transfer speeds of this NAS so slow?

The best I can get is about 120 Mbit/sec on a gigabit network. The web interface states it's connected in gigabit mode.

For comparison : my home build WHS can get around 500 Mbit/sec on the same network, and it's not even using raid.

I tried everything, I can not get above 120 Mbit/sec.

I am really disappointed with the network performance of this NAS. For that price I could have gotten 2 x 1.5TB hdd's and add them to my WHS. 

I have the Linkstation Quad 4TB and I, too, noticed slow transfer speeds across my gigabit network.  I'm getting around 10-15 MB/sec which is between 100 - 150 Megabits/sec.

About the same here. It almost looks like it's using the gigabit connection in 10/100 mode. They should really look into this and find a solution, because using raid is an expensive solution if all you are going to achieve is 10/100 network speeds.

As a test I transfered a large file to the Buffalo Linkstation, and while it was going at 100-120 Mbit/sec I started another large file transfer to my WHS, and my combined speed jumped to 600 Mbit/sec. So it's clearly not a network issue, a router issue but an issue related to the Linkstation.

As far as real world speed goes, read/write should be about 7 megabytes per second on a Gigabit ethernet network, or 3MB/sec on a 100 base-T network. Typically, a 1 GB transfer should take around 5-7 minutes. The speed is, for the most part, limited by the processor on the unit.

So there's no point hooking this up to a gigabit network, as you can get at best 10/100 performance capped by the units processor capabilities.

I wonder why the implementation of a gigabit network interface if the unit can only perform at 10/100 connectivity. Does this mean the processing power is upgradeable?

No you cannot upgrade the processing power.  Remeber these are not file servers with huge processors.  They are very limited and were inteded as a storage unit.
