But Mak i think that is the luck of the draw. Seriously, I've had hard drives die after two years of use, but still have TONS of USB devices that were given to me at conferences and what not from YEARS ago. Granite I understand what you are saying, I don't use those on a daily basis. Which is right, but I have two USB drives I've had for the past 4 years that I work with on a bi-daily basis, and they still work.
I just think it depends on usage - and ALL THINGS EQUAL, a SSD will last longer than a traditional platter one. Now instead of having a moving piece malfunction, the SSD memory can no longer hold information. It is also about quality, if you don't use quality memory chips, yes a SSD will die sooner then the traditional QUALITY platter.
