Just a data point: I'm on an Intel SSD (120GB) since Aug 2009 -- running Debian testing all the time. I do not upgrade daily, but often. I have _not_ done any of the optimizations mentioned on the wiki. I have on average approx 15GB free on the drive. Obviously, I ran a kernel <3.2 for most of the time. I do lots of compiling on this SSD. So far, I have nothing to complain about and consider this drive as fairly reliable.
