In order to decide how to get the most of your devices you need
to know what technologies are available and their implications.
As always there can be some tradeoffs with respect to speed,
reliability, power, flexibility, ease of use and complexity.
Many of the techniques described below can be stacked in a
number of ways to maximise performance and reliability, though
at the cost of added complexity. This is a method of increasing
reliability, speed or both by using multiple disks in parallel
thereby decreasing access time and increasing transfer speed. A
checksum or mirroring system can be used to increase
reliability. Large servers can take advantage of such a setup
but it might be overkill for a single user system unless you
already have a large number of disks available. See other
documents and FAQs for more information. For Linux one can set
up a RAID system using either software md module in the kernel),
a Linux compatible controller card (PCI-to-SCSI) or a SCSI-to-
SCSI controller. Check the documentat
