DS210j problems, speed and connection drops

[Rasterman]

Here is my setup:
Asus G53JW notebook with Real SSD 256GB SSD & GigE Win7 64bit
Realtek PCIe GBE Family Controller
DS210j with 2 RAID-1 Drives 2GB WD20EARS 64 MB Cache
DLINK DIR-655 Router

Write to DS210j 14 MB/s
Read from DS210j 35 MB/s
these are as reported by the windows 7 copy dialog, when dealing with 1 3GB file.

According to the SNB bench the DS210j should be 26/53, as my performance is about HALF this what do I need to tweak or do?

I started tweaking some settings on my desktop, and after I tried to enable Jumbo frames in the device manager on my network controller I can read from my NAS but can't write to it, does anyone know why? When I try to copy a file to the NAS it just hangs on the copy dialog and says "Discovering files..." I don't think enabling Jumbo frames is going to correct my performance problem anyway? Jumbo worked and did improve performance a little bit when I had XP, but now that I have Win7 it doesn't work?

Jumbo frames works only if all devices support it, including router switch. But don't bother messing with them anyway. I have found with current hardware and OSes, jumbo frames don't help much.

I'd try the same benchmark reading and writing to a desktop PC before I blame the NAS.

Ok thank you, once I get my other desktop back online, should be this week, (with an Intel G2 160GB SSD) I will test reading and writing to it.

Also on my NAS what might be effecting it is the free space, it is about 70% full.

I have tested my network between my two computers and I am now more confused than before, the results are all over the place, I repeated the 4 tests a couple of times the results were all similar.

I don't know if its my network settings, the fact that xp and windows 7 don't get along or what is going on, but any advice would be appreciated.

My machines are:
XP 32bit, Intel Core 2 Duo 2.4Ghz, Intel g2 160gb SSD
Win7 64bit, 740qm 1.7Ghz, Crucial Real SSD C300 256GB
Both have GigE connections and are connected to a DIR-655 router
Both drives are more than capable of reading and writing over 100MB/s.

For the test I copied a 1.4GB file from one machine to the other, the top graphs are when I was on the XP machine and copied to/from the Win7 one. The bottom graphs are when I was on the Win7 machine and copied to/from the XP machine. You would think the graphics would match up, but they aren't even close, what the hell...

It seems only in 1 case (when I'm on the win7 machine and copying from the xp machine) do I get GigE speeds of over 100MB/s.
