TRIM is a feature that allows solid state drives to automatically handle garbage collection, cleaning up unused blocks of data and preparing them for rewriting, thereby preventing slowdowns that would otherwise occur over time as garbage data accumulates. Support for TRIM has been included in OS X (10.6.7), but Apple decided that native TRIM support is limited to stock Apple drives (users who have installed third-party SSDs into their machines have reported that TRIM is not enabled). Chameleon enables support TRIM changing the driver IOHACIBlockStorage by removing the lock on third-party drives, also a back up copy is included to restore the original, you can find it at:
With the MORE DISK INFO button you can check System Profiler Sata additional info over your drives and controller.
This button allows you to repair disk permissions on current drive.
Read smart data of your system drives as model, serial number, firmware version, support smart and status, temperature and threshold temperature. Smart data are collected by objective-c and cocoa.
Hibernate "0" (desktop default)
The system will not back memory up to persistent storage. The system must wake from the contents of memory; the system will lose context on power loss. This is, historically, plain old sleep.
Hibernate "3" (laptop default)
The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image.
The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want hibernation slower sleeps, slower wakes, and better battery life, you should use this setting.
Drive space can be limited, especially if you are using a solid state drive of modest size.
If you have ever put your Mac into 'hibernate mode', you might find that space equivalent to the amount of memory in your Mac is suddenly
missing from your boot drive (e.g. if your Mac has 8GB memory, an 8GB sleepimage exists)
The missing space can be mysterious, because the file won't be shown by the Finder, so it's just space that's apparently gone missing.
Disabling the sleep image you can earn the space previously occupied, restoring hibernate values to 3 or 25 also the sleep image is restored.
The Sudden Motion Sensor is designed to detect unusually strong vibrations, sudden changes in position, and accelerated movement.
If the sensor detects any of these, it instantly parks the hard drive heads to help reduce the risk of damage to the hard drive in case of impact.
Apple has adjusted the Sudden Motion Sensor feature carefully to provide the best balance between protecting the hard drive and preventing
unwanted activation of the Sudden Motion Sensor. Most Apple portable owners never need to turn this feature off. Apple suggests that you not
modify the settings unless absolutely necessary.
With only SSD drive on your system you don't need SMS.

Patching trim means modify the kext (driver) responsible for managing disks. The change is reversible and you can always manually reset it. Enabling patch is your responsibility and at your own risk.
