You will have to make quite the effort to burn trough a consumer SSD in machine with normal use for a year. 256 GB * 3000 gives a lot of write information.
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 ;) )
