RAID 1 – Possible solution in situations which do not require high storage
capacity.
RAID 0, Concatenated - These are not recommended due to lack of
redundancy and data protection. Since long term archival storage is indented
in some ways to be a backup of important files, it is not a recommended
solution.

RAID 5 – Recommended for file servers that require maximum storage
capacity and only base data protection and performance.
RAID 50 – Recommended for those solutions that require a balance between
storage capacity and performance.
RAID 1 – Possible solution situations which do not require high storage
capacity.
RAID 10 – Possible solution for situations that require greater availability and
redundancy but not as much disk capacity.
RAID 0 – While this solution is not fault tolerant, RAID 0 may be useful for file
servers that require better performance and maximum storage capacity, for
example, where backups are expected to maintain data in the event of a failure.
Concatenated – This solution could be use for situations that require maximum
scalability as drives could be added as storage needs grow. For file servers
