With any of the seven series of Intel chipsets, you get trim commands to any raid array even SSD. So it is not that big of a problem or headache inducing these days, except when something goes bad on one drive and that is no different than any other platter based system. I have my two 840 Pro 512's in raid 0 for a couple months and can't say there has been any problems with it, for large file transfers, there are some noticeable speed but nothing like the older parallel ide drives in RAID 0, those nearly doubled the speed. I mostly did it so I didn't have to fuck around with install locations, one drive seen by the OS for all game and data intensive apps.
