I am not a statistician too, but I believe that if you put 2 disks you have twice the chance of one of those disks fail, if you have 3 disk, 3 times more chance and so on.

So, in essence, if you use 2 disks on RAID-0 your chances double to lose everything compared to a single disk. If one guy is brave enough to put valuable data on a single cheap disk, he must be twice braver to use 2 disks on RAID-0 :)
