Which is why I asked why SataII. The interface is flawed because it has no future to it. Meaning that the SataII drive you by today is limited physically and only has throughput gain. (+-2%). If something is improved on the technology, your SataII drive you get now will do nothing. I would suggest going the a Raptor.
I only have one of these drives, and it's in a rather loud enclosure already, so I don't know. I use SCSI and SAS drives in my system, so I'm about as loud as you can get as far as drives go. I'm sure someone can help with question.
