Roman, Thanks for the suggestion. I would probably consider keeping TRIM if I had less free/unpartitioned space on my SSD. Currently all partitioned space is just a fraction (about 1/3) of total SSD size. In this situation I prefer to make sure that my raid is consistent than to prolong the life of SSD a bit.
