I don't want to sound it like off-topic, but why do you guys need a TRIM support for a 3rd-party drive? My early-2014 MBA came w/ Apple SSD and TRIM is enabled by default
Because Apple enabled TRIM support on SSDs identified as Apple drives - only. This excludes all third party drives, except Angelbird. Angelbird labels their drives as Apple drives. Do a search and some reading and you'll learn more.
