1. Introduction
This Low Profile PCI-Express Host Adapter is a controller board to support Low profile PCI and
regular size PCI both in one card. The card can upgrade your desktop computer to have 2 ports
Serial ATA II transfer rate of 3 Gb/s (300 MB/s).
The board can be used to upgrade your desktop computer to have 2Ports Serial ATA Channels
and support RAID 5, RAID 0+1, RAID 0, RAID 1 and JBOD features. It accepts host commands
through the PCI Express 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 & Generation 2 transfer rate of 1.5 Gbps / 3Gbps. It
comes completely with drivers for Windows 2000, Windows XP, Windows 2003.
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.
