Third party SSDs never have TRIM enabled. There is an exception: in Mac OS X 10.10.4 and later have a command you can run in a terminal called “trimforce” that will enable TRIM support for ALL SSDs, not just Apple SSDs. What do you do if you’re on an older version of OS X? Well, Apple doesn’t give you trimforce on older versions, so the only answer is to “hack” the storage driver in OS X to bypass the check.

TRIM is critical for SSD health over time. TRIM tells the SSD that data in a block is no longer needed. Without TRIM, the drive can’t clean itself up internally because it has to assume that any block which was written is still needed, and depending on the amount of over-provisioning in the drive, you could end up in trouble without TRIM. Flash memory doesn’t work like a normal disk it can be written in “pages” (small, i.e. 4KB) but can only be erased in “blocks” (a set of many pages, i.e.
