My setup:
ReadyNAS Ultra 4, 2x1TB 7200rpm WD, 2x2TB 5400 WD, XRAID2:
Our NASes are different but maybe what I learned could help you a little.
WNDR3700 router:
Win7 x64, 4GB RAM, 7200RPM HDD, Intel Core i7-950
RealTek PCIe GBE Family Controller 8168 GigE NIC:
I use LAN Speed Test v2.06 (http://www.totusoft.com...well worth the $5) to test my speeds. I then confirm them with drag-and-drop and with the speed measurement in GoodSync during a backup routine.
MBps - MegaBytes per second
Jumbo Frames off-- Write: 56 MBps Read: 98 MBps
Jumbo Frames on-- Write: 11 MBps Read: 86 MBps
Jumbo Frames does not work well with my NIC & ReadyNAS (even with a direction connection to the NAS). The WNDR3700 is supposed to be able to handle Jumbo Frames on the switch portion of the router.
With jumbo frames off, write speeds will peak and hold at around 62 MBps for the short run (5-10 minutes), but on long backup routines with mixed file sizes using GoodSync, typical average write speed is 55-56 MBps over an hour or two.
Slow copy speeds on Vista and Win7 are a much lamented problem that seems to be hit or miss:

There are lots of Google solutions that you could try, but here are a couple thoughts:

- Try a direction connection to the NAS to bypass the WNDR3700: http://sphardy.com/web/readynas/how-to- ... -readynas/
- Use TCP Optimizer: http://www.speedguide.net/downloads.php. Maybe you've got some IPv4 setting out of whack?
