Lindy ATA-133 manual What Is RAID, Package Contents, RAID Redundant Array of Independent Disks

Supports software-controlled ATA bus tri-state.

Supports device specific timing registers.

Supports device read-ahead and write-ahead capability under Virtual DMA.

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
