Yeah...that's what that TRIM Command was for....to address the problem of write-overs in SSDs; a bottleneck. Before, the unit had to erase data before it could write "over" old data. With the TRIM, it can write immediately; makes it faster and increases longevity. Still, like you say, it is a somewhat new technology and a bit pricey. May wait a year or so for the prices to come down and see if they come up with some more innovations to make them even better. But I see hard drives going the way of floppy drives in about 10 years...perhaps sooner if the SSD prices drop. Hope springs eternal...
