SATA 300 will transfer data twice as fast as SATA 150. However, you may only
notice the difference with large transfers since seek time and other system
factors are also involved

Does anyone know the easy answer to which is faster and is it really
noticeable?? Considering upgrading one of my 160gig seagate barracuda's
(sata 1.5) to a new barracuda sata 3.. Any responses as always
appreciated
