10. SOFTWARE RAID1
RAID1 (Redundant Array of Inexpensive Disks Level 1) is a technology generally referred to as disk mirroring.
RAID1 is not disk mirroring that is accomplished by the RAID controller (hardware). RAID1 constructs a system
where two HDDs are combined and managed as one RAID1 system (array) by software. Should one HDD fail, you
can read the correct data from the other HDD. RAID1 uses two HDDs, but the capacity available is only equal to the
capacity of one HDD.
