Caution
• Before installation of the controller card, we recommend that users study this manual first. This RAID
manual has more information on RAID architecture, RAID features, RAID installation, RAID settings and
Management software for the RAID5 GUI (Graphical User Interface).
• Windows Device Manager cannot recognize hard drives without the correct RAID settings in place.
• The working data on your existing hard drive may NOT work when you migrate it to a RAID Host Card
configuration.
• After driver installation you can install the SATARAID5 GUI for RAID management. Before the
SATA RAID5 GUI installation, you must remove all existing SATARAID GUIs (or Java SATARAID GUI) to
ensure your new SATARAID5 GUI works without issues.
• RAID sets can be created and managed by either the BIOS utility setting or the SATARAID5 GUI setting
under Windows.
• If you’re using a used hard drive with the RAID5 card you must perform the “Delete RAID Set” under
the BIOS settings. The reason this is necessary is because the used hard drive has system data on it
which may cause recognition issues when configuring it for use with the RAID5 card.
• RAID 0 and RAID1 setups require at least 2 drives, with RAID5 requiring 3 drives and RAID10 requiring
4 drives. If only one drive, make sure to have “Concatenate” or “Contiguous” setting.

Introduction
The board offers the ability to upgrade your desktop computer to RAID 5, RAID 0+1, RAID 0, or RAID
1 as well as JBOD. The board can control four independent Serial ATA channels. Each channel has its
own Serial ATA bus and will support one Serial ATA device. The board supports Serial ATA Generation 1
transfer rates of 1.5 Gb/s (150 MB/s).

Features
PCI Interface
Compliant with PCI Specifications, Revision 2.2.•
Integrated PCI DMA engines.•
32 bit, 33/66MHz fully compliant PCI host interface.•
High Speed Serial ATA Interface
Four high speed Serial ATA interface ports, each supporting 1st generation Serial ATA data rates•
(1.5Gb/s).
RAID 5 (Distributed Parity RAID) has Highest Read data transaction rate and Good aggregate transfer rate.•
Provides RAID 0 (Stripping) to greatly increase the performance of data transfer by simultaneously writing•
data to 2 drives.
Provides RAID 1 (Mirroring) to protect the data from a disk failure by writing identical data on 2 drives.•
RAID 0+1 (Mirrored-Stripping) combine both Striping and Mirroring technologies to provide both the•
performance enhancements that come from Striping and the data availability and integrity that comes
from Mirroring.
JBOD is a virtual disk that combines all disk drives as one entire disk drive.•
Fully compliant with Serial ATA 1.0 specifications.•
Supports Spread Spectrum in receiver.•
Independent 256-byte FIFOs (32 bit * 64 deep) per Serial ATA channel for host reads and writes.•

RAID - Redundant Array of Independent Disks
RAID technology manages multiple disk drives to enhance I/O performance and provide redundancy in
order to withstand the failure of any individual drive, without loss of data.
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping is discussed
as a RAID Set type, it actually does not provide fault tolerance. With modern SATA bus technology,
multiple I/O operations can be done in parallel, enhancing performance. Striping arrays use multiple disks
to form a larger virtual disk.
Disk Mirroring (RAID 1)
Disk mirroring creates an identical twin for a selected disk by having the data simultaneously written to
two disks. This redundancy provides instantaneous protection from a single disk failure. If a read failure
occurs on one drive, the system simply reads the data from the other drive.

Mirrored-Striping (RAID 0+1 also known as RAID 10)
A Mirrored-Striping Set does just what it says, combining both Striping and Mirroring technologies to pro-
vide both the performance enhancements that come from Striping and the data availability and integrity
that comes from Mirroring. When data is written to a Mirrored-Striped Set, instead of creating just one
virtual disk as Striping would do, a second Mirrored virtual disk is created as well.
Parity RAID (RAID 5)
Parity or RAID 5 adds fault tolerance to Disk Striping by including parity information with the data. Parity
RAID dedicates the equivalent of one disk for storing parity stripes. The data and parity information is
arranged on the disk array so that parity references are written to different disks. There are at least 3
members to a Parity RAID set.
Parity RAID uses less capacity for protection and is the preferred method to reduce the cost per megabyte
for larger installations. Mirroring requires 100% increase in capacity to protect the data whereas the above
example only requires a 50% increase. The required capacity decreases as the number of disks in the
group increases.

Just a Bunch of Disks (JBOD/Contiguous)
JBOD (also known as Contiguous) means a logical drive that can either be an entire disk drive or a segment
of a single disk drive. For this card, the JBOD function only supports one disk. JBOD here is a Contiguous
configuration option when using the “Create RAID Group” within the SATARAID5 Manager Utility.
