Is it possible to connect a SATA II hard drive to an IDE motherboard with an
adapter? I don't expect to get 300 mb/s but its no sense to buy another PATA
drive when SATA is the new standard
It makes perfect sense, because the PATA drives exist to be
used for the exact thing you are doing, to just plug into
the board and use it. You won't get better performance from
an SATA II drive connected this way if that is what you were
thinking, with rare exceptions such as certain drives that
just don't come in PATA versions (WD Raptor for example).
Regardless, it is possible to use an adapter fine, they do
exist and the cost will depend on how much searching you do
for best price, as a tiny item like this can vary widely
between about $10-30. You might check at your favorite
online vendor, and add it to your next/other parts, order,
so you don't suffer such a high % of cost from the shipping
charge.
