just thought my HDD in my HTPC was going to fail as i had random freezes of windows explorer(not internet explorer), as i had a spare hitachi 500Gb 5400rpm lappy hdd lying round i thought id clone it to that until i can buy a new full speed one.
Anyways it got me thinking since laptop drives are generally quiter even 7200rpm models, they are also alot smaller easier to mount in my scratch built htpc case, my question is....
What is the advantage of a physically bigger 3.5inch full size hard drive? is it due to platter density or something???
thanks in advance, just thinking of buying a WD 500Gb scorpio black 7200rpm laptop drive as a replacement as i used one for my wifes laptop,
it works quite well and is alot quieter than any full size hdd i ever used, which is really important in any htpc

could you run it with normal sata ports and power?
