“It is a well known fact that hard disks keep getting bigger and
cheaper every year. This is more true for ATA disks (also referred
to as DMA or IDE disks). IDE disks are no longer limited to 5400
RPM (speed in revolutions per minute). Old IDE disks below 1G
capacity either belong to a museum or collected by some people for
fun.“Most business computers running critical applications (servers)
usually use SCSI disks with software or hardware RAID. Now, there
are companies that provide ATA RAID solution for cheap IDE disks.
Promise Technology and HighPoint are two popular companies in that
group. Already, a lot of motherboard manufacturers are including
ATA RAID chips on board. These chips are either Promise FastTrak
chips or HighPoint chips. This means that even a home user can
afford a RAID solution today. While it may not be as good as the
traditional hardware RAID on SCSI disks, it is definitely better
than just a pair of IDE disks with no RAID…”
