Buy whoever gives you a good warranty. All hard drives will fail eventually, and even a good brand can have bad batches; only the warranty matters.
I ditched 7200 RPM drives in favor of 5400 RPM because they are hotter, louder, and wear out faster--all because the faster speed generates heat, noise, and wears down moving parts.
I have Windows and my main apps on a 7200 RPM drive, but games, music, movies, and backup goes on the more reliable and quiet 5400.
BTW...One is a Western Digital, and one is a Samsung. No problems with either. And Sazar is right about grommets and the like.
