RAID levels Function/Applications Advantages/Disadvantages
RAID Recovery
Function:
Identical (mirrored) data is
stored on two drives.
Boosts the functionality of
RAID 1 with valuable
features.
Applications:
Any application that requires
a simple data protection
method.
Advantages:
Provides high fault
tolerance.
Users can choose to mirror
data continuously or on
request.
Data recovery is quick and
easy.
Allows hot-plugging of
mirrored drive (with eSATA
or docking station HDD).
Enables easy migration to
non-RAID.
Disadvantages:
Only half of the total drive
capacity can be used for
storage.
Storage space may be
wasted if the capacities of
the primary and recovery
HDDs are different.
RAID 5
Function:
Distributes data across three
HDDs. If one HDD fails,
RAID 5 allows data to be
recovered from the other two
HDDs.
Applications:
A good choice for large
amounts of critical data.
Advantages:
Data redundancy
Improved performance and
capacity
High fault-tolerance and
read performance
Disadvantages:
During a RAID rebuild after a
hard drive fails, system
performance can be
decreased.
