hi.... I am replacing my 80 gb seagate barracuda PATA with a 120 gb sata hard drive. but i am really confused as to which brand should i go in for. There are a large number of variables such as buffer size, native sata support, performance, noise level etc. I really want a high performance drive (not SCSI though) within a budget of Rs 5000. Please help me in pin pointing the brand........seagate, maxtor, western digital, hitachi.........thanx
