This study performed an automated cut off DC power directly to the drive -- which seems reasonable to me - and is more practical for testing, and I personally like that it's testing the hard drive as a more "self-contained" unit.<p>Power fault often occur at the AC power, however, and only later gets to the DC power. This is impractical to test as there are too many configurations/variables and it's much harder to test accurately, but it would theoretically be interesting to see if AC power faults to a system power supply had a different affect on the data than DC power faults.
Isn't this the definition of FUD? <a href="http://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt" rel="nofollow">http://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt</a><p>> Fear, uncertainty and doubt (FUD) is a tactic used in sales, marketing, public relations,[1][2] politics and propaganda.<p>>FUD is generally a strategic attempt to influence perception by disseminating negative and dubious or false information. An individual firm, for example, might use FUD to invite unfavorable opinions and speculation about a competitor's product; to increase the general estimation of switching costs among current customers; or to maintain leverage over a current business partner who could potentially become a rival.<p>>The term originated to describe disinformation tactics in the computer hardware industry but has since been used more broadly.[3][dubious – discuss] FUD is a manifestation of the appeal to fear.<p>>About Robin Harris<p>>Robin Harris has been a computer buff for over 35 years and selling and marketing data storage for over 30 years in companies large and small.<p>>Robin Harris is a president of TechnoQWAN, a consulting and analyst firm in Sedona, Arizona.

I believe that FUD like this is the main reason SSD costs are still relatively high.
