Hi all using build 7000 on following specs. C2D 2GHZ 2GB ram P945 chipset. I have 3 hard drives (sata II) Y=350GB used Z=550GB used backing up to a 1.5TB drive. I used windows backup and after 12 hours it was only at 51%??? I have tested copying files btw the drives and I get about 65MB/s up to 120MB/s depending on the type of files. Any ideas?
