SiS965L SATA RAID Setup Guide
Introduction for SiS965L SATA RAID Function
The SiS965L S-ATA Host controller only support two serial ATA on two independent
ports. The Serial ATA RAID is designed to provide a cost-effective, high perfor-
mance RAID solution that adds performance and/or reliability to PC desktops and/or
servers using Serial ATA/150 hard disks.
Serial ATA RAID function supports striping (RAID 0), mirroring (RAID 1), and span
(JBOD). Please note that the function supports hard disk drives only.
With striping, identical drives can read and write data in parallel to increase perfor-
mance. Mirroring increases read performance through load balancing and elevator
sorting while creating a complete backup of your files. Span would increase the logic
hard disk space.
Serial ATA RAID striped arrays can double the sustained data transfer rate of Serial
ATA/150. Serial ATA RAID fully supports Serial ATA/150 specification of up to 150
MB/sec per drive, depending on individual drive specifications.

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 sev-
eral 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.
