Ok, my friend tells me that 7200RPM, although faster, is not a wise decision. He says that since it is spinning so fast, it is more likely to malfunction in the future and has a much shorter lifespan than the 5400RPM. Is this true? From my experience, all I can say is that my 3 hard drives which were 7200RPM have all failed me after a year or two of use. I ended up with clicking noises at first, and then they slowly died. However, I have had a 5400RPM drive for about 3 or 4 years now and its still working beautifully? Can anyone clarify this for me?
