    3) You have a four year old machine - one day the RAID controller dies.
    The company that produced it has been acquired by someone else, and
    the product is no longer availble. Can you get a new adapter with
    firmware that can actually read your disks? Or are your data lost?
    Can you find a replacement controller on e-bay? And would you want
    to?


    Anyway, not wanting to spread more FUD than stricly necessary: It's a
    matter of cost/benefit and risk management. Everyone has their
    personal preferences on this - and even if it wasn't so, let's not
    begin to pretend that there is a simple answer to what's "best".
