I'm about to get a new drive for backing up two macs on my network. I know airport extreme airdisk is slow, but I don't mind because I can just leave it on at night and let it all take care of itself. I just want something reliable, durable and nicely designed...from a company that will stand by their products. I've been looking at these drives: newertech ministack v2 and v3 newertech ministack NAS (USB2 and ethernet) Lacie D2 HD Quadra 500GB Lacie Enet Disk Mini Any good advice? Thanks!
