if i buy a seagate bracuda 7200rpm 32mb cache sata harddrive. will it prform better if i use it in a sata2 or sata3 port?or will it perform the same? * +

your cable speed (The SATA) is the 'bandwidth' so obviously it'll perform better if information moves through a faster cable. You you HDD can transfer 5000Mbps but with it wont transfer that if you cable that is used to transfer is slow as s**t. Understand? And 7200rpm doesn't tell you anything about the speed of the HDD. Just so you know. * +

If the drive is a sata2 drive, using it in a sata3 port will not boost the speed. The interface on the drive will only do 3Gbits/s, even if the port on the board can do 6Gbits/s. * +

Transfer rate too depends upon rpm ah ! Combined by factors like quality of disk in hdd, power supply , materials used for creating pci of hd , quality of casing as disk are sensitive to external envioroment and type of motherboard and yup those sata cables and at ends processor * +

the win 7/vista, experiance is bugged with very little variation on the drive number a ide 5200rpm drive can give the same rating as a 1000rpm raid config. si it realy is near usless for a performance measure. hd tune is the only realy reliable method to test a drive and its speed. the drives transfrer speed is down to its udma mode if its sata in some cases rpm means nothing. some 7200 rpm drives * +

like the samsung spinpoints can burst mode faster than 1000rpm drives. giving 250-300MBps with an average read write speed of 120-140MBps on a single drive, while other drives with higher rpm can only burst to 133MBps because they have a lower udma. * +
