well, no not really. In a RAID0, there is no Redundancy. It's more accurately a AID, or just an Array of Inexpensive Disks. For Redundancy in a striped array, you need parity information to ensure against failure of *any one disk*, and that's a RAID4, 5 or 6 (6 giving you double failover with not one, but TWO sets of parity information distributed throughout the array, as opposed to RAID4 which has one set of parity information written to a single disk in the array and RAID5 has that single set of parity information distributed throughout the array). In a RAID1, there is 100% failover redundancy but this is not a backup solution. All it is, is an insurance against physical failure of ONE HALF of the array.
If you use a RAID, you need to be aware that whatever you do to the data on the array, is what you do to it. IF you delete it in such a way as to render it irretrievable, then that's it. Unless you have a backup.

Not true! The disk space on Surface just takes into account that there are no worthwhile apps to install.

**REDUNDANCY is NOT BACKUP**

Or perhaps people don't bother deleting stuff they no longer need until they start to run out of space.
