RAID Native SATA-150 4Ports PCI Host
This Manual for the Models of 4 Channels SATA RAID HBA:
Model A: Serial ATA RAID Internal 4 Ports
Model B: SATA RAID External 2 Port + Internal 2 Port
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
