Third party SSD optimization Yosemite Unaware of the current issues with Third-Party SSD support on Yosemite I went ahead and bought a 128 GB Crucial MX100 SSD.

I hear a lot of problems about enabling Trim on Yosemite etc.

I recently download Chameleon SSD Optimizer. Using this software I enabled Trim and smart optimization.

Question 1:

What is all the commotion about Trim? Chameleon seemed to have no problem enabling Trim.

Question 2:

What options should I set with Chameleon SSD Optimizer (i.e - Sudden Motion Sensor, NOATIME, Time Machine, Sleep Mode/Image)?

Basically, what is it that Chameleon does to optimize SSD performance and where does Trim come into this, and why are people giving out, this is my main curiosity? Everything seems OK to me...

I would like as much info as possible but assume no prior knowledge
The TRIM command was introduced to facilitate “garbage collection” of deleted data, allowing the SSD to reset those “unused” blocks back to an “empty” state. This allows for better performance for many SSDs.

All Chameleon does is hack your SSD to enable TRIM. What the hack does is basically tell the OS that the non-Apple SSDs in the system are Apple drives so TRIM can be engaged with them.

Some people have not been able to boot up with Yosemite because it doesn't support TRIM but programs such as Chameleon have created a work around. The real issue is that the TRIM hack needed to be applied every time you upgraded to a new OS version, which was a real pain. But now that is not a issue. Hope this helps.
