I have 2 TS-1.0TGL/R5 Terastations. I want to back up from one to the other. I am transferring approximately 15 GB per hour. If I copy a file instead of using the Disk Backup in the web interface, I get about the same speed. Both stations say 1000Mbps on the front panel. Both stations are connected to a Netgear Switch in ports that are next to each other. The Netgear says the ports are transmitting 1G Full. I just upgraded the cable connecting the terastations to the switch to cat 6. The speed did not change. Before moving the second terastation to the Netgear switch, I had it connected to a 100Mb switch and I got 15 GP per hour there. It did not help to move the station to a 1G connection. The lights on the Netgear switch are green which indicates 1G. The firmware is the latest 1.04. Shouldn't a 1G connection do better than 15 GB per hour? Is the limiting factor how fast the terastation can write? I cannot use Jumbo Frames because the switch does not enable jumbo frames by port and I can't do it for the whole network.
