The use of RAID to do live backups of physical hard drives may have an influence on the amount of storage space that can actually be accessed on a hard disk. Is it beneficial to backup if doing so consumes half of your disk space? What RAID configuration is best for a home computer to use to protect its hard drives from failure due to frequent power outages?

Live backups of physical hard drives may be created using RAID, although this can reduce the usable space on the disks. Do you think having a backup is important enough to warrant sacrificing half of your disk space? What RAID setup is best for a home computer to protect its hard drives from the effects of frequent power outages?

Live backups of physical hard drives can be produced by setting up a RAID array, although doing so will reduce the original hard drive's capacity. Would you rather have backup at the expense of using up half your disc space instead? The frequency of power outages affects the best RAID configuration for a home computer system that is susceptible to hard disk failures due to frequent power outages.

RAID is a technique used to offer live backups of physical hard drives even if it reduces the hard drive's usable capacity. Would you prefer to have backup at the expense of about half of your disc capacity, or the opposite? Which form of RAID is ideal for a home computer system that often endures power outages that might cause hard disk failures?
