RAID 5 is not the most fault tolerant -- although it is better than RAID0
or no RAID at all.

It's all about budget but you have to think:

  "When one of my disks dies (which is inevitable), what systems will go
   down, how many people will be affected and how long will it take me to
   get them back up?  Also, how frequent will these disk failures be -- the
   more disks, the more frequent disk failures are"

You should also have back-ups, but you should use RAID for reliability and
if possible to gain performance, depending on your need and budget.
