1. Introduction
This Low Profile SATA RAID 2 Port PCI Host Adapter is a PCI to dual Serial ATA host
controller board which can support Low profile PCI and regular size PCI both. It
provides a 32bit, 33/66 MHz PCI interface on the host side and dual, fully compliant
Serial ATA ports on the device side to access SATA Hard disk drive.
The board can be used to upgrade your desktop computer to have dual Serial ATA
Channels and support RAID 0 and RAID 1 features. It accepts host commands
through the PCI bus, processes them and transfers data between the host and Serial
ATA devices. The board should be connected to SATA target device and will take the
data, serialize it and output it for transmission over the SATA interface. The board can
control two 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 rate of 1.5 Gb/s (150 MB/s). It
comes completely with drivers for Windows 98, Windows Millennium, Windows NT 4.0,
Windows 2000 and XP.
RAID, Redundant Array of Independent Disks, greatly enhances two main areas of data
storage: performance and data integrity. By using RAID 0, also known as Striping,
performance of sustained data transfer rates is greatly enhanced by simultaneously
writing data to 2, 3 or 4 drives. The second benefit of RAID is data redundancy. RAID 1,
Mirroring, writes identical data on two drives or sets of drives, thus protecting the data from
a disk failure. If, for any reason, one drive were to fail, your data is secure and available
from the mirrored second drive.
