Low Profile Ultra ATA-133 RAID PCI Host
1. Introduction
This Low Profile Ultra ATA-133 RAID PCI Host Adapter is a PCI to dual Ultra
ATA-133 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 Ultra ATA-133 ports on the device side to
access ATA Hard disk drive.
The board can be used to upgrade your desktop computer to have dual Ultra
ATA-133 Channels and support RAID 0, RAID 1 and RAID 0+1 features. 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.
