May I miss-understood the wiki, xfs is stated as not being complete for 
linux, a zfx is I think commercial?
Can you update that?

One of the 1T samsungs in the md raid10 isn't entirely happy but mdadm 
has not fussed about it, and smartctl seems to say its ok after testing. 
  Other than that the gui access delay (30+ seconds) problems I have did 
NOT go away when I moved /home off the raid to another SSD, so I may 
move it back. One of the reasons I ma rsync'ing this /home back to it 
every other day or so, takes < 5 minutes.
