RAID defines a "fault tolerant" model for data stored on storage device. There are two types of solution possible. 1. Software RAID take two IDE or SATA/SCSI disks and work on a logical disk interface mediated via a software RAID driver. 2. Hardware RAID typically a JBOD enclosure that plugs to SCSI interface on the box. internally it has multiple disks, but it exports a single logical disk interface. To implement RAID for the purpose it is used for ie. "fault tolerance", an administrator must use atleast two disks ! That's how it is in the real world, where disks do fail ! For personal study, one may want to do it with one disk. Anyways, here is a link for reference for all, http://en.wikipedia.org/wiki/RAID thanks Saifi.
