RAID 1 (Data Mirroring)
RAID 1 is called data mirroring that copies and maintains an identical image of data
from one drive to a second drive. It provides data protection and increases fault
tolerance to the entire system since the disk array management software will direct
all applications to the surviving drive as it contains a complete copy of the data in
the other drive if one drive fails.
RAID 0+1 (Stripe Mirroring)
RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 0+1
solution for improved performance plus resiliency. The controller combines the
performance of data striping (RAID 0) and the fault tolerance of disk mirroring
(RAID 1). Data is striped across multiple drives and duplicated on another set of
drives.
JBOD (Spanning)
A spanning disk array is equal to the sum of all drives. Spanning stores data onto a
drive until it is full then proceeds to store files onto the next drive in the array. When
any member disk fails, it will affect the entire array. JBOD is not really a RAID, and it
does not support fault tolerance.
RAID 5
RAID 5 stripes both data and parity information across three or more hard disk drives.
Among the advantages of RAID 5configuration include better HDD performance, fault
tolerance, and higher storage capacity. The RAID 5 configuration is best suited for
transaction processing, relational database applications, enterprise resource planning,
and other business systems. Use a minimum of three identical hard disk drives for this
setup.
1.2 RAID Configurations Precautions
1. Please use two new drives if you are creating a RAID 0 (striping) array for
performance. It is recommended to use two SATA drives of the same size. If
you use two drives of different sizes, the smaller capacity hard disk will be
the base storage size for each drive. For example, if one hard disk has an
80GB storage capacity and the other hard disk has 60GB, the maximum
storage capacity for the 80GB-drive becomes 60GB, and the total storage
capacity for this RAID 0 set is 120GB.
