Why software RAID?

Software RAID provides better reliability than not using RAID. Each filesystem that is part of a RAID-1 pair is duplicated on two disks. If the operating system detects that one of the copies of the filesystem is being affected by faulty disk input/output, it will stop using that copy, but continue to function normally using only the other copy. In some of the type R operating systems, the install procedure does not properly install the boot loader grub on the second disk of a RAID disk pair.
