I know that Serial ATA is better than Ultra ATA hard drives. Though is it worth the extra money? I've got a 160GB Seagate Ultra ATA hd (factory refurbished), though i was wondering whether or not it would be worth it to sell that one on ebay for like $80.00 and get a 80GB SATA hd. Is it worth the trouble or is the permorance boost so minor it wont make a noticeable diffference?
NOTE: I have a Seagate SATA hd in the comp already (which by the way, is REALLY loud), would I be able to use an SATA and an Ultra ATA hds at the same time?
