    Which makes me think that I will use Software Raid 5 and convert the
price of the card into RAM.
    This should be nice for a budget server.
    Gonna investigate now if Linux software RAID5 is rugged enough. Can
always buy the a card later if not.

    Thanks all for the advice, you were really helpful.
