agreed. It still isn't bad to consider RAID 5, but in my application it's more money than I am looking for to do it right. I can do a RAID 0 properly for much less. True that the risk is there, but (knock on wood) I don't think that is extremely likely. Plus, I am already willing to accept if it happened that I wouldn't cry about it. Get everything I need backed up on another drive and the less important things (games, movies, etc.) can have the small risk of being lost.
On another note, I did notice that newegg has the 640GB caviar black drives on sale for 65 bucks. With that, I could buy say 3 of those for $194. That would give me better performance than 2 x 1TB with similar space.
I am highly considering this option. Thoughts?
