Tweaking SSD drives for less wear seems to be all the rage nowadays. On that subject is Write Caching still relevant on SSD drives? Does it make a difference if it is turned off?

Most advise to leave it on, since write caching is a function of the OS and main memory and not the hard drive – Moab Nov 13 '10 at 2:14
