To Tux or not to Tux

Oh, yes, redundancy, not striping - raid 1.  Been a while since thinking 
about raid, opps.

One goes boom, the system still boots and has a copy of your stuff, 
hopefully telling you in a useful way to replace the one that died.  
Expect the ssd to die.

That asus laptop with the uefi bios actually shipped with 2x 256gb ssd's 
in raid-0 oddly, so one dies, it all goes poof.  Weird to see that on a 
consumer device, but I redid it as redundant raid-1.  My current dell
