Really do not think that SSDs will totally kill-off mechanical spindle drives since any data lost on a SSD is pretty much gone with the wind. Been getting less and less surprised hearing about some pretty highly ranked SSDs being un-usable and toast after a short amount of time and being used by some pretty savvy users. Noticed too in the last week or so that some of the prices for HDDs is really pretty decent about now, and not all that sure how long that will be until the workers in China will be getting an increase in pay ....next month ??
You're never to old to learn something stupid.
