Features one 256-byte FIFO (32-bit x 64 deep) per IDE channel for host
reads and writes.
=
Features ATA to PCI interrupt masking.
=
Features command buffering from the PCI to ATA.
=
Features Virtual DMA: Bus master transfer on the PCI bus and PIO
transfer on the ATA bus.
=
Features Watch Dog Timer for fault resiliency.
=
Provides RAID 0 (Stripping) to greatly increase the performance of data
transfer by simultaneously writing data to 2 drives.
=
Provides RAID 1 (Mirroring) to protect the data from a disk failure by
writing identical data on 2 drives.
=
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. This card provides two RAID Set types, Striped
(RAID 0), Mirrored (RAID 1) and Mirrored-Striping (RAID 0+1).
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
