So, I got this shiny PowerMac G5 from my uncle, and it came with a 250GB HardDrive. I also have two 1TB HDD that I have no clue what to do with. How can I put those HardDrive to good use? I want to put 2 HDD's into this PowerMac and make those 2 harddrives be read as one. This PowerMac will be my main machine, which means it'll have all my documents, Minecraft saves, music, photos and a bit of video (various animé); this data amounts to roughly 500GB. From what I could understand RAID-0 is perfect, but the problem is that if one HD fails, all is lost, RAID-1 is great, but I'll be loosing half of my HDD space. My question: Which is better: RAID-0 (1TB + 250GB) and a Time machine backup of 1TB OR RAID-1 with 2 1TB drives?
