Another :thumbsup: for building a RAID 0 Array (for the right reasons ofcourse). Let me put my .02c in before all you anti-raid 0 nazis chime in.
First and foremost, I've been using RAID 0 arrays in my video editing systems for years now, and in my opinion it's worth every penny in terms of speed and performance. I'm a gamer too, and have also noticed that certian game maps load much, much, much faster on my video editing systems than non-RAID systems - so take that into account.
As for all you paranoid users out there screaming that your data is 2x likely to fail, start living life and enjoying a RAID 0 array. Everybody regardless of your hard drive configuration should have a fool-proof backup system in place, so guess it doesn't matter then...right?
There are way too many threads in the last few months babbling about how RAID 0 is going to ruin your life, destroy your data & is not worth it. I say go for it, atleast if you do and don't like it - you can post about it with some experience to back you up unlike many people posting about it that haven't even tried it.
