1RAID Introduction
This chapter introduces the basic concepts and features of RAID.
1.1 RAID Functions
RAID is the abbreviation of “Redundant Array of Independent Disk”. Simply put,
RAID is a technology that combines multiple independent hard disks (physical hard
disks) in different ways to form a group of hard disks (logical hard disks), thus
providing higher storage performance than a single hard disk and providing data
backup. Depending on the different combinations of disk displays, RAID can be
classified into different RAID levels. With data backup, users can restore corrupted
data from the backup to ensure data security. In addition, users can manage the
drive group just like a single drive, and can also partition or format it. In brief,
operations on a RAID array are the same as those on a single drive. The only
difference lies in that a RAID array delivers a higher storage speed and enables
automatic data redundancy backup.
RAID supports:
Automatic detection of failed drives
Rebuilding of data in bad sectors
Drive backup
Hot-swap drives
Drive capacity expansion
1.2 RAID Levels
Various RAID levels are available to provide different data access speeds, security
levels, and cost performances. Users can select appropriate RAID levels based on
their actual needs in terms of availabilities, performances, and capacities of
storage systems. The commonly used RAID levels include RAID 0, RAID 1, RAID 5,
RAID 6, RAID 10, RAID 1E, RAID 50, and RAID 60.
1.2.1 RAID 0
Also known as striping, RAID 0 divides data into multiple data blocks with the same
size and writes them into different drives in the array. With data distributed across
multiple drives, data read/write is performed concurrently on these drives.
Therefore, the capacity and data transfer rate of RAID 0 is theoretically N times of
those of a single drive ("N" represents the total number of drives composing RAID
2
0). However, RAID 0 cannot ensure data security since it does not support data
redundancy, and therefore is applicable only to scenarios that require high I/O
performance but low data security.
Figure 1-1 RAID 0
1.2.2 RAID 1
RAID 1 is also referred to as mirroring. In a RAID 1 array, each data drive has a
mirrored drive. Data is written to both data and mirrored drives simultaneously,
and is read only from the data drive. If a data drive fails, data will be read from its
mirrored drive. After the failed drive is replaced, data can be rebuilt from the
mirrored drive. RAID 1 features high reliability but its effective capacity is half of the
total drive capacity. It applies to scenarios where high fault tolerance is required,
such as finance, banking, etc.
Figure 1-2 RAID 1
1.2.3 RAID 5
RAID 5 consists of rotating parity and independent access. The parity information is
evenly distributed to all drives in the array by certain rules instead of being written
to a fixed drive. Therefore, each drive contains both data information and parity
3
information. If any drive fails, data on the failed drive can be rebuilt from the parity
bit data on other drives in the array. RAID 5 requires at least 3 drives. The
advantages are better utilization of the capacity of all redundant drives configured
in the array and excellent read/write performance. Note that drive failures will
affect the throughput rate. This means a longer time is required to rebuild data
than it takes in RAID 1 configuration.
Figure 1-3 RAID 5
1.2.4 RAID 6
Compared with RAID 5, RAID 6 adds a second independent parity block for double
parity. The two independent parity systems use different algorithms to ensure high
data reliability. Data processing is not affected even if two drives fail at the same
time. However, RAID 6 requires larger drive space for storing parity information
and has a higher "write penalty" compared with RAID 5. Therefore, RAID 6 provides
lower write performance than RAID 5.
Figure 1-4 RAID 6

1.2.5 RAID 10
RAID 10 is a combination of RAID 1 and RAID 0. RAID 10 requires at least 4 drives. It
delivers the best performance, protection, and capacity among all RAID levels. In
RAID 10, mirrored drives are in pairs, and their data is stripped on the entire array.
In most cases, RAID 10 can resist failures of multiple drives at the same time, and is
able to better ensure stable running of the system. Data loss is least likely to
happen in RAID 10. RAID 10 is a perfect choice for data protection because of the
same redundancy feature as RAID 1 (mirroring).
Figure 1-5 RAID 10
1.2.6 RAID 1E
RAID 1E is the enhanced version of RAID 1, which integrates data striping and
mirroring to enhance the data recovery capability. However, since all data gets
written at least twice, the load is increased in the RAID processor, thereby lowering
read/write speed of drives. Like RAID 1, RAID 1E data is mirrored, so the logical
drive capacity is half the total capacity of all member drives. RAID 1E requires at
least 3 drives.
Figure 1-6 RAID 1E
5
1.2.7 RAID 50
RAID 50 or RAID 5+0 is a combination of RAID 5 (distributed parity) and RAID 0
(striping). RAID 0 allows data to be striped and written to multiple drives
simultaneously, and RAID 5 ensures data security by using parity bits evenly
distributed on drives. Therefore, RAID 50 delivers higher data security than RAID 0
and better read/write performance than RAID 5.
Figure 1-7 RAID 50
1.2.8 RAID 60
RAID 60 or RAID 6+0 is a combination of RAID 6 and RAID 0. RAID 0 allows data to be
striped and written to multiple drives simultaneously. RAID 6 ensures data security
by using two parity blocks distributed evenly on drives.
