I am not an expert on SSD's but I Familiar to know what TRIM is and what it does. what I can not find is if the performance degradation that a drive may experience by not having TRIM in the OS is permanent or if it can be reversed. Subsequently I would like to know if my October 2010 MBA 11.6" that has been running for 9 months with no TRIM will be repaired (if needed) by now having the TRIM supported. anyone know?????
