Have a new i7 MacBook Pro on the way. Will be replacing the stock 500GB/5400RPM HD and putting it in an enclosure; need a good speedy replacement (preferably 500GB). Looked around but sadly haven't found any solid or up-to-date benchmarks (hopefully someone here can steer me in a good direction); so far I've narrowed it down to these 4 HDs: - Western Digital Scorpio Blue 500GB 2.5 SATA 5400RPM 8MB (Model: WD5000BEVT) - Western Digital Scorpio Black 320GB 2.5IN 7200RPM 16MB 12MS (Model: WD3200BJKT) - Seagate Momentus 7200.4 500GB 2.5IN SATA 7200RPM 16MB (Model: ST9500420AS) - HITACHI Travelstar 7K500 500GB 7200RPM 16MB Cache (Model: HD20500 IDK/7K) Heard great things about the two WD drives and some not so great things about the Seagate (high failure rate); but still can't come to a definitive decision. Also (assuming it would fit), what's the consensus on the new 1TB WD drive? Any and all advice/help/comments are appreciated. Note: SSDs are not an option for me due to small sizes and the price of the size I'd need to buy. Also, waiting til early next year for the next round of SSDs isn't an option either.
