Purpose of Class
This class introduces the student to R.A.I.D. technology (Redundant Array of Inexpensive Disks), it's applications and gives advice for using disk redundancy in the real world.
In RADE 5 you said that if you have 32 discs you would have one that would back up your data. I don't see how that can be true. If you use 3 discs of = capacity and any one disc can fail without data loss then 33% of total capacity is used over the span of the discs for redundancy. If you had 32 discs for a total of 8tb disc space and would need total backup capacity of 2.64 TB spanned over the 32 discs to be able to remove any one drive.

I hate to nitpick, but RAID 10 is not RAID 1 on top of 2 RAID 5s. RAID 10 is RAID 0 on top of 2 RAID 1s. What you were reffering to is actually called RAID 51 (RAID 5 + RAID 1).
