14. Supports FIS-based switching with Port Multipliers.
15. Commands and Scatter/Gather Tables per Port.
16. Two Pin headers on board for LED connection.
17. Completely with drivers for Windows 2000, Windows XP and Windows Server 2003.
18. Provides RAID 0 (Stripping) to greatly increase the performance of data transfer by
simultaneously writing data to 2 drives.
19. Provides RAID 1 (Mirroring) to protect the data from a disk failure by writing identical data on
2 drives.
20. RAID 0+1 (Mirrored-Stripping) combine both Striping and Mirroring technologies to provide
both the performance enhancements that come from Striping and the data availability and
integrity that comes from Mirroring.

2. What Is RAID
RAID - Redundant Array of Independent Disks
RAID technology manages multiple disk drives to enhance I/O performance and provide
redundancy in order to withstand the failure of any individual member, without loss of data.
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping
is discussed as a RAID Set type, it is actually does not provide fault tolerance. With modern
SATA bus mastering technology, multiple I/O operations can be done in parallel, enhancing
performance. Striping arrays use multiple disks to form a larger virtual disk.
Disk Mirroring (RAID 1)
Disk mirroring creates an identical twin for a selected disk by having the data simultaneously
written to two disks. This redundancy provides instantaneous protection from a single disk failure.
If a read failure occurs on one drive, the system reads the data from the other drive.
RAID - Redundant Array of Independent Disks
RAID technology manages multiple disk drives to enhance I/O performance and provide
redundancy in order to withstand the failure of any individual member, without loss of data.
