1. Introduction
This RAID Native SATA-150 4Ports PCI Host Adapter is a PCI to 4Ports Serial ATA host
controller board. 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 4Ports Serial
ATA Channels and support RAID 0, RAID 1 and RAID 0+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 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 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.
