Yes, I was refering to RAID.
I too thought TRIM was fine on single drives, even with the MS AHCI driver.
But I had read a few reports a while back that it was working now in RAID as well with the Intel driver.
Never really looked further into however, as I do not have a RAID array to test.
According to the intel website, it will pass trim, but not in a raid array. I think the confusion was that before the RST 9, it would not pass trim if there was a raid array even if the SSD was not part of the array. The newer intel drivers will pass trim in a raid array as long as the SSD is not in the array. I hope I made sense.
Same for OCZ Revo drives (which are arrays) - they do not support Trim. On the other hand I really wonder how much difference that makes in real life. I still have two Gen1 80GB Intels - one in a desktop and one in a laptop. I am very happy with their performance despite the relatively slow write speeds in the measurements (I guess the 4K is still relatively good). See here:
Extreme Systems is conducting a rather interesting experiment on SSDs, seeing how much you can write to them before they die.
This will be interesting to see.
It would seem OEM wanted a guarantee of 20GB per day.

Intel went one step further and delivered 5x what the OEMs requested. Thus Intel will guarantee that you can write 100GB of data to one of its MLC SSDs every day, for the next five years, and your data will remain intact. The drives only ship with a 3 year warranty but I suspect that there'd be some recourse if you could prove that Intel's 100GB/day promise was false.
Lets see how close these figures actually are :)
