My 74GB Raptor is nearing the end of its 5 year warranty period and I think its starting to show its age so I'm checking on replacement drives. Seems like I can get a new 150GB Raptor for about the same price as a 750GB HDD so I'm unsure which to choose. I've got a 750GB from WD as a storage drive and it seems fast but how will it measure up to a Raptor? I've seen the reviews here and think it would be fine but wanted some feedback from other folks here. Thanks.
