   * This Volume Group can be split into Logical Volumes; in essence different Partitions.
   * LVM provides the ability to resize these Logical Volumes very easily.
-  * LVM is not a replacement for RAID, as it only supports mirroring or stripe.
+  * LVM is not a replacement for RAID, as LVM does not provide any options for redundancy or parity that RAID provides.
-    * Using LVM for resilience without RAID would result in twice as much storage being needed; a waste.
     * Therefore it is best to be have LVM in conjunction with RAID.
