If you are really concerned about data recovery and can chunk up your 
filesystem mount points so things fit on a single disk (usually not too 
hard with 1 or 1.5 TB drives available now) just use software raid1 
since you can simply mount any single disk from it and access the files. 
  It becomes much more difficult with other raid levels or multi-disk lvm.
