Chameleon SSD Optimizer is an optimization tool for Solid State Drives. It can enable TRIM on non Apple-branded disk, increase durability reducing I|O writing cycles, set hibernate mode and save space disabling sleep image. Chameleon is able to read sata system profiler info and you can easily check trim status, disk speed or properties.
