SATA Raid

[Ted Mittelstaedt]

Well you want several things here:  redundancy, add in card to preserve
your existing motherboard, SATA, and cheap.

So far you have found those four things are incompatible, that is why
your
here.  I'm telling you point blank that they are incompatible and to
give up looking for that combo.  Get rid of one of these items and
your being reasonable.

If you want redundancy and cheap, and add-in card, then get a udma
133 card and discounted disk drives.

If you want redundancy and cheap and SATA then replace your motherboard
with one that has a SATA raid chipset on it and these existing SATA
drives
you apparently already have.

By the time you buy a SATA raid card you can pay for a new motherboard
that
is better and faster and already has SATA raid on it.
