Not so obvious.  They should work at least on a short run.  But as I 
have told, I've heard number of rumors about mps(4) and 8TB Seagates. 
Though nothing confirmed, only some instability, that nobody is really 
motivated to debug now.  Next 93xx line of mpr(4) HBAs still seems cost 
few times more on EBay thogh, so there is a choice.
