That's very outdated information.

Many mainstream SSD manufacturers have evolved their design to include
garbage collection and optimizations that do not require TRIM. Enabling
TRIM on such SSDs actually *increases* wear on the drive, because it
causes data to be moved around unnecessarily. Also, keep in mind that
TRIM is an ATA command that cannot be sent to SSDs connected with
Thunderbolt, Firewire, USB, or PCIe (as in new Mac Pro models). In those
situations, enabling TRIM is effectively useless anyway, and as I said,
manufacturers have implemented other ways of doing garbage collection
and optimization that do not depend on the TRIM command.

Do so at your own risk. Best of luck with that.
