When you pay less than 1/4th the price of one drive for the controller
card directing all your drives, is it really necessary to ask this question?

Two large pizzas cost more than a Syba/Rosewill/Koutech/etc SATA card.
The pizza is consumed in one night, maybe some for breakfast.  Would you
trust a day worth of pizza with your RAID?  With your data?

One tank of gas for the average car today costs $50, the same as two of
these SATA cards.  The gas is gone in a week or two.  You want the cards
to run for 2-4 years.

Your drives cost anywhere from $400-$1000, yet your controller maybe
$50.  Do I really need to say any more?  Spend $150-250 on a decent
SAS/SATA controller such as an LSI or Adaptec and you won't have to
worry about this kind of thing.
