This has been covered ad nauseum.
This term is defined by the American Heritage Dictionary as:
Argumentum ad nauseam or argument from repetition or argumentum ad infinitum is an argument made repeatedly (possibly by different people) until nobody cares to discuss it any more. This may sometimes, but not always, be a form of proof by assertion.
I specifically said a few things to clarify that statement I typed in much haste without much thought. First, I remembered seeing data (from the website you actually linked yourself) that showed a few 7200rpm drives with better reliability and lower rate of defect in the past; this was the reason for the statement in the first place but on second thought I probably should have not said "statistically" and just left it as my suggested opinion. Secondly- I clarified my statement to my true feelings. My true feelings are that neither a 5400rpm or a 7200rpm drive are inferior or superior in reliability- or that a great difference in reliability exists between them. I generally believe they are the same. If I personally had to choose- I would side with 7200rpm being more reliable because I believe they have been around longer- and get used more in demanding enterprise applications, and that much of that engineering and parts get trickled down the line to consumer drives because of economies of scale. I have seen some statistics (you linked them above) that suggested there is not a huge discrepancy between enterprise and consumer HDD's in actual reliability and I attribute that to these reasons. In comparison the 5400rpm drives are newer to market and also a new design that is never proven in a demanding environment and shares no brother or sister products used for those purposes. That is probably why you see a decent failure rate with those 5400rpm drives and there has been some issues in the past with their reliability. 5400rpm drives were never engineered to be ultra reliable or durable, or designed for very demanding usage like the faster HDD's. It's only right now that we are even seeing the newest products like the Seagate NAS or the WD RED even try to tackle these issues. I believe the introduction of these drives and the marketing around them is to attract customers from a specific growing segment of HDD buyers, and also a bit of reaction to some of the issues the 5400rpm drives had in those configurations. So in general my feeling is most HDD's are the same and there's not enough difference between a 5400rpm and a 7200rpm in reliability to use that as an important factor in a purchase decision. The data you posted seems to suggest more that they are all the same than they are different- even though "statistically" you could pick out two models and make it show what you want to a small degree
For the very last time:
I should not have said "statistically" and rather just said my point without it.
I don't think there is much difference between 5400rpm and 7200rpm in reliability
I DO NOT think that 5400rpm are more reliable and I hate the myth that suggests that they are
I do think there is a serious difference between these HDD's in price, performance, and features - and that is much more important. (to me at least)
Can we let this go now ? This is like the 10th time I said all this and I'm nearly certain no one wants to read it anymore.
