I recently moved from a single ssd to double RAID 0 setup and it seems like the write speeds are disproportianantly low. I have two 120 gb intel 330 series SSD's and am running intel ssd toolbox and rapid storage technology which should give me trim support although it's not clear from looking at the settings. I've tried turning write-caching on and off and it seems to make no difference. My sequential write speeds are in the 900mb/s range while write speeds are around 250mb/s. Any ideas?
