That should be 'disks' and not 'disk'.

Raid 5 works just fine when applicable. Raid 0+1 is used a lot fault tollerence and additional performance gain from reading the mirrors in road-robbin fashion. I used RAID5 in other parts of the operating system or on datafiles that are not high in OLTP volume.

The thing to note is that not just one RAID strategy is the solution for all applications or systems. It is a combination of RAID levels you are looking to use.
