Any recommendations? I've been looking at the LaCie 2TB, FW 800, 7200 rpm model for my PBG4, so I can use it with Logic 7.0 (audio recording). 1. I'm afraid that it'll breakdown in an abnormally short amount of time? What's the usual life span? It's RAID 0. 2. Would I need a backup for the backup? Or is that too weird?? 3. Anybody have one of these? How has it worked out? Issues? Concerns? Thanks in advance for any input.
