Its not that it ignores it, rather it just not implement the cleaning in real time. With all other TRIM aware (and supported) SSD controllers, as soon as the TRIM command is sent to it...they carry it out. SF controllers don't. They simply update their internal map of used and unused blocks with the new data. This is done on purpose. The exact purpose has not been explicitly stated (or at least I have never seen it), but I believe it is to further reduce writes. SF will never say if or when they REuse "used" blocks as that falls under the heading of "trade secrets" but it is my beleif that this is why they do it...and also how they can claim a longer MTBF even though the NAND is not rated for as many writes as it is in other high end SSDs. ;)
