Question! I've been using my MacBook Pro for about 4 years. I put in 120GB SanDisk SSD that I got for a really good price. Lately it's been EXTREMELY slow (running 10.10.5) and I find it very odd that this has started all of a sudden. Then it hit me, was this thing ever running TRIM? No it wasn't. So my question is if an SSD's health can be restored somehow after 4 years of not running with TRIM enabled.
