RAID 5 corruption, RAID 1 more stable?

On several occasions I have seen situations where faulty UPS's caused
servers wtih RAID 5 arrays to reboot continuosly which caused
corruption to either the RAID array itself or the file system. I am
considering recommending RAID1 whenever possible because I suspect
that it would be more resillient under the same conditions because I
have two seperate copies of the system and I do not suspect that
mirroring would mirror NTFS corruption or suffer from the problems of
RAID 5 array corruption. I would like to hear your opinions on this.

thanks
