"Hard to beat"5.0 starson by heavynotebookuser
Pros: amazing fast with win7 64-bit especially system start, office applications, sata II notebook most likely beats standard modern desktop pc's in terms of speed and IQ (energy, etc.) with this HDD
Cons: could be some more metal workmanship, it's just a feeling issue, can't complain about durability
Summary: I would buy the product again to tune up an older sata II notebook with standard 5400 rpm HDD. You can't go wrong. And my battery lasts half an hour longer.
