+7. Should I use RAID0?
+~~~~~~~~~~~~~~~~~~~~~~
+  No.
+
+7b. Why not?
+~~~~~~~~~~~~
+  RAID0 has zero redundancy. If you stripe a RAID0 across X disks, you
+  increase the likelyhood of complete loss of the filesystem by a factor of X.
+
+  The same applies to LVM by the way.
+
+  If you want/must used LVM or RAID0, put it on RAID1 arrays (RAID10/RAID1+0,
+  or LVM on RAID1).
