To cut space and maybe just maybe save a little power I have got the asustor nas.
whs 2011 to htpc download file is 93 MB/s
asustor to htpc download same file 11 MB/s
whs 2011 to laptop 9 MB/s
asustor to laptop 500 to 600 kb/s so a 390 MB file takes around 20 minutes to transfer.
These are with Windows 7 Home Premium 64 bit going to Computer then Network and copy from asustor and server from there to a folder on computer.
On setting up asustor it immediately upgraded to latest firmware.
I have upgraded modem firmware to latest as well with no change.
So where to start to improve speeds. On the reviews I have seen they all get better speeds
