RAID collectively refers to several different methods ("RAID levels") of
organizing multiple disks into a single storage volume. You can choose the
level of failure that the volume will be able to withstand, with
corresponding tradeoffs in performance, manageability, and expense.
The level that you are talking about here is RAID-5.
You can even layer RAID levels together, for example RAID-0 over RAID-1,
providing a lot of flexibility. What is the situation that you have where
you are looking for an alternative to RAID?
