Hi, new to the forums and I am thinking about upgrading my current hd a 4200RPM drive to a 7200RPM. I read another post about the drive being ata-5, well I looked at newegg and they have ata-6, now my question is ... is ata-5 compatible with ata-6. By the way this is the drive I was thinking about buying http://www.newegg.com/Product/Product.asp?Item=N82E16822146020
