I just came across this in another thread, & realized that the solid state drive in my 2011 i7 Lion 10.7.4 mac mini is not a Toshiba, it is a 240 gb Mushkin drive. I read that only Toshiba have this TRIM support. I read that macs with SSD drives that may not have trim support get very slow after a while. I have had my mac mini since April 2012, & it is still fast, but reading about TRIM has me concerned. how do I know if my SSD drive has TRIM support? how do I check for it? & if it does not, is there a simple way to get it?
