How to keep an SSD in shape on Yosemite?

As of OS X 10.10, Apple uses kext signing. Ever since it has become difficult and dangerous to manually activate TRIM for third-party SSDs on OS X.

So I am wondering what are my options to sustain my SSD's write speed.

• Are you aware of any alternative approach, that does not require disabling kext signing?


• Are there tools or tricks to manually clean up a SSD (i.e. issue a TRIM command)?


• If I decided to temporarily use a tool like TRIM Enabler how long would it need to be activated, in order to clean the disk?
