  • 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).
