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.

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.

RAID Basics
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.
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.
Performance hints and recommend setting

2.
