Looking to replace my very old firewire connected iomega. I have a Neil Polton on order currently but am now having second regrets. I have an iMAC (2010) and the nice thing about the firewire is I can also use my auxiliary LACIE CDR burner. It looks like I will have to unplug the Lacie burner to use that port for the new Neil Polton soon to arrive. Does anyone have any insight on whether I made a good choice or not? I use my old iomega as a Time Machine Back up and that will be the main purpose for the new Neil Polton drive. Any input is greatly appreciated!
