I was given a NAS drive by a follow Geekzone member.
I got my HDD in it Sata 2 and its a Sata 2 NAS drive over Gigabit Ethernet all the way to my PC. I have isolated the modem and PC out of it and my NAS seems to be the issue.
Throughput to store items on the NAS averages about 3MBp/s - 10MBP/s and never faster. Its a RND2150.
