Sick thoughts :P
So, I was just thinking, what if I had two 80 GB HD's and a 160 GB HD? I could then gstripe the 80 GB's, and then on top of that stripe those with the 160 GB. Then I'd have around 320 GB or so, I could then gstripe that with a 320 GB HD.
Ohhh the possibilities. By that time, I'd probably just use some sort of gvinum, since apparently it can do raid 5 over hard drives that are not the same size. Something i'd like to eventually do as a way to keep my data safe and a secure.
