Appendix A - What Is RAID?
RAID,.short.for.Redundant.Array.of.Independent.Disks,.is.a.combination.of.two.or.more.disks.with.the.aim.of.providing.fault.tolerance.and.improving.
performance..There.are.several.different.levels.of.RAID,.with.each.one.providing.a.different.method.of.sharing.or.distributing.data.among.the.drives..
The.ShareCenter®.Pro.supports.JBOD,.RAID 0,.RAID 1,.RAID 5,.and.Standalone.
RAID 0:
RAID.0.provides.data.striping,.which.spreads.out.
blocks.of.data.over.all.drives,.but.does.not.provide.
data.redundancy.
Although. performance. is. improved,. the. lack. of.
fault.tolerance.means.that.if.one.drive.fails,.all.data.
in.the.array.will.be.lost.
