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.
