5.7 What is RAID?
This section will give you an overview about the RAID system and introduce
the basic background and glossary which you need to know before using
“SiS RAID Controller Application”.
1. RAID: (Redundant Array of Independent Disk Drives) use jointly
several hard drives to increase data transfer rates and data security. It
depends on the number of drives present and RAID function you
select to fulfill the security or performance purposes or both.
2. RAID 0: Also known as “Stripping”. All of the data are distributed
evenly to all of the existing drives. You gain benefits on performance
because the data transfer rate is multiplied by the number of drives.
However, RAID 0 has high risks of data security. All of the stored
data will be lost if even any one drive in the RAID set crashes.
3. RAID 1: Also known as “Mirroring”. Two hard drives are required.
The goal of RAID 0 is to ensure data security. Data is written to two
or more drives synchronously. That is, 100% duplication of data
from one drive to another.
4. RAID 0+1: Also known as “StripeMirror”. At least four hard drives
are required. RAID 0+1 is a combination of RAID 0 and RAID 1.
Data is striped into two drives then mirrored. It provides high
performance and high data protection. This is a costly solution as
RAID 1 because the two mirrored drives represent an expensive
insurance.
5. JBOD: (Just a Bunch of Drives). Also known as “Spanning”. Two or
more hard drives are required. Several hard disk types configured as a
single hard disk. The hard drives are simply hooked up in series. This
expands the capacity of your drive and results in a useable total
capacity. However, JBOD will not increase any performance or data
security.
5.8 Installing Software Drivers
SiS provides RAID driver for SiS180 SATA with RAID function.
1. For RAID function, SiS180 support RAID0, RAID1, RAID 0+1
and JBOD.
