I will receive my new 2.93Quad sometime next week and am trying to figure out the best performance and backup plan for me. I do graphic design, Quark, PS, Flash, have dozens of web tabs open, use EyeTV, have a large iTunes library. (I'm currently still on a 1.8DP G5 from 2004 .... and suffering from slow iTunes library issues etc) I want to install a striped RAID set with three 1TB Hitachi HDs. I want to partition each of the three HDs first: 1. 30GB scratch (for PS) (total 90GB) 2. 55GB system & apps (total 165GB) 3. 250GB work files/data (total 750GB) 4. 300GB new iTunes media (total 900GB) 5. 300GB existing iTunes media (total 900GB) I would add one 2TB WD Green HD in bay4 and use CCC to backup partitions #2-4 daily I would use an external 1TB HD to backup the static 900GB of iTunes media from partition #5. I imagine this would give me fast performance for apps and secure backup in case one of the HDs in the striped RAID fails. BTW, if one of the RAID drives fails, how time-consuming is it to replace the content from my 2TB CCC clone? Do all three RAID HDs have to be re-written? What do you think of the proposed setup?
