RAID Overkill for Most Home Users

A RAID array is the ultimate in external hard drives and unlimited digital storage. RAID stands for Redundant Array of Independent Disks. The idea here is to use multiple external hard drives together to increase capacity, performance and redundancy. A proper RAID set-up will allow mirrored disks to work together to serve busy Web sites, sharing the information flow equally. Then if one disk has a problem, the others take over. Users won't even know the difference. RAID used to be an expensive option, suitable only for large-scale business or educational uses. But today you can purchase a RAID array for your home PC, allowing anyone to boost the capacity of their PC to more than a Terabyte (1000 GB) of storage. Who needs all this capacity? Anyone who absolutely needs to have mission-critical redundant storage available for high client use. Busy commercial web sites are starting to use RAID arrays to make sure they can always serve the public, no matter how great the need. But for most home users, this is really overkill.
