software is much more prone to failing than hardware. it is changed far more often than hardware.
Yes, recovering data and setting the RAID back up is the point
of a RAID. Redundancy is pointless if we can't restore the RAID. Hardware always
fails, it's just a matter of time. You could carry a software RAID controller around with you on a CD (for example: Knoppix) and it will never be changed and always work.
There's a Dell storage RAID at work, I think its 4 x 250Gb in RAID 5, and there's a software RAID in my house that's 4 x 250gb in RAID 5 running Debian.
Not only does the software RAID perform
better, but I have never
had it fail, whereas we've had to rebuild the Dell 3 times. This is in a 10 month time frame.
