Just to expand my thought process a little more...
I don't think you can make generalized statements anymore about the reliability of a particular brand of hard drives or even a particular model of hard drive within that brand. I have tried all sorts of different drives (Samsung F4, EARS, EARX, EADS, Reds, Blacks, etc) and all seem to have different characteristics and even different number of platters within a particular model. I have had some that were noisier than the others as well --- again sometimes within a particular model.
The reason for this is simple: All the hard drive manufacturers change components and firmware frequently. So while one particular "run", "lot" or "batch" may be particularly unreliable and problematic others will be excellent. (As an aside I also don't subscribe to the purchasing of drives from different "lots" theory as I think this increases your chance of getting one of these problematic drives). So I think unless you can test hundreds or even thousands of drives and know what is inside each drive (and what firmware they are running) you really cannot make a generalized statement at all. A normal consumer just doesn't have the sample size to make a statistically significant conclusion. This is complicated by the fact that by time these drives will have failed (1-3 years in most cases for what I think is deemed an "early failure") they are often not relevant to current options and no longer available for purchase.
So you have to weigh all of these things into consideration when purchasing drives or considering what to use. I have had excellent luck with Green drives but haven't had bad luck with Red or Black drives either.
I don't see the point of Black drives for storage so they are out for me (I use an SSD for my OS) unless they are a great value, quiet and a model that is energy efficient.
I love Green drives and Red drives (5400 RPM) for storage especially for HTPC and HTPC software based servers as I think they are usually the best bang for the buck. I would gladly purchase a red drive for the extra warranty alone but probably would only spend an extra $10 or so.
That's my $.02.
