I am looking to replace my WHS with another type of setup and was looking at FreeNAS, or Drobo, etc...but was thinking about OS X server. Question though. Does it support any type of RAID 5/6? Or is it only 0 and 1 that it supports? What I mean by support is a software RAID by OS X as other OSes support this. And if it does, does it allow you to grow the array?
