RAID Levels
This section describes RAID levels that the Onboard RAID Controller (LSI Embedded
MegaRAID™) supports. The available RAID levels are RAID0, RAID1, and RAID10 (striping of
RAID1).
Characteristics of RAID Levels
The table below lists the characteristics of the RAID levels.
Level Function Redundancy Characteristics
RAID0 Striping No • Data read/write at the highest rate
• Largest capacity
• Capacity: (capacity of single HDD) ×
(number of HDDs)
RAID1 Mirroring Yes • Two HDDs required
• Capacity: capacity of single HDD
RAID10 Striping of RAID1 Yes • Four or more HDDs required
• Capacity: (capacity of single HDD) ×
((number of HDDs) / 2)
RAID0
In RAID0, data to be recorded is distributed to HDDs. The mode is called "striping".
In the figure below, data is recorded in stripe 1 (disk 1), stripe 2 (disk 2), and stripe 3 (disk 3)… in
the order. Because RAID0 allows all HDDs to be accessed collectively, it can provide the best disk
access performance.
IMPORTANT: RAID0 cannot have data redundancy. If a HDD is
defected, the data saved in the HDD cannot be recovered.
