I purchased an Intel 34nm 160GB SSD 12 months ago to install in my MBP 13". It has been an excellent drive, however, started to significantly slow down over the last few months. The only way I was able to recover to original speeds was by formatting the entire drive as a windows drive and running the Intel SSD Toolbox app in Win 7 (manual trim command). Finally I reinstalled OSX and voila drive was as fast as when I initially purchased it. Either Intel needs to release a OSX compatible toolbox app or Apple needs to build the functionality into OSX. I know this has been a topic before but thought I'd share my experience.
