I've seen a number of normal HDD failures. I think that the first one that I've seen, been with a double-5 inch slot hard drive, which was failing to start spinning at times. You've had to turn the PC box abruptly, to make it spin ;)
But as of now, have to see an SSD fail. Longest running that I have now is a Linux box that've been up since Oct/2007. (Heh, cool part about that linux box - there are no moving parts at all - no coolers, no nothing. Even in the power supply ;) )
Sounds cool :) I am not saying i have never seen HDDs fail, but in the almost 20 years i have been computing heavily, it might have been about 3 in my own machines, while i went through 2 SSDs in 4 years. Id still never go back to HDDs as my system drive :)
