I've got an SSD that came with my laptop (Sony Vaio) from 2009, and it is still running strong despite having the operating system installed on it, i.e. lots of reading and writing going on on it. It's probably a cheap SSD as well, considering that it was a preinstalled one, but it speeds stuff up tremendously. Photoshop for example only takes a couple of seconds to start, which takes like half a minute on a normal 7200 rpm HD.
