[QUOTE="MacInWin, post: 1643411"] If you look [URL="http://www.cindori.org/software/trimenabler/"]here[/URL], there are some stats that claim that without TRIM a "used" SSD is about 10% slower than a fresh drive. And if you read the link from Cindori that harryb2448 posted, you'll see that the developer said From what I can see, the TRIM function moves pages from some blocks to others to free up the block for reuse. If you do that with TRIM, it's done in the background, but if you don't, it still gets done when a write takes place and needs the space. That's why the slowdown over time. Frankly, I'm not sure I'd notice a 10% drop in write speeds on my SSD, given how fast it is anyway, so I'm not going to fret over it unless someone comes along with a more compelling reason for TRIM.
