Click on the Start Menu -> All Programs -> Accessories -> System Tools -> Disk Defragmenter -> Click on the Configure schedule button -> Uncheck the Run on a Schedule box -> Click OK -> Close the window.
Disable Drive Indexing
With super fast read times, indexing the drive is almost unnecessary and can cause multiple needless writes to your SSD.
Click on Start Menu ->Computer -> Right click on your SSD-> Properties -> Uncheck Allow files on this drive to have contents indexed in addition to file properties -> Click OK.
Disabling Pagefile or Reducing Size:
Disabling Pagefile can benefit you (decreasing writes to the SSD) if there’s plenty of RAM running in your system.
Click on Start Menu -> Right-Click Computer -> Properties -> Advanced System Settings ->Advanced Tab-> Performance Settings -> Advance Tab -> Click Change under Virtual Memory -> Uncheck Automatically manage paging file size for all drives -> Click on No paging file -> Click Set -> OK -> Restart your computer.
Enable Write Caching
This will show you how to enable write caching to have better performance for a storage device.
Open the Control Panel -> System and Security -> Device Manager -> expand Disk drives -> Double click on the listed storage device that you want to enable write caching for -> Click on the Polices tab -> By default, "Enable write caching on the device" is checked under the Write-caching policy section. If not, then check it -> Select (check) the "Turn off Windows write-cache buffer flushing on the device" box -> Click on OK -> Click on Yes to restart the computer to apply.
Turning off "Windows Write-cache Buffer Flushing on the Device" runs the risk of data loss in case of a power failure without actually shutting down the machine.

Change the Power Plan To Maximum Performance
The Power settings in Windows 7 is not automatically set for maximum performance. By default the power plan in Windows 7 is set for a balanced performance with energy consumption on hardware. So you may not get the optimal performance from windows 7 if this is the case. So we need to change the power plan to High Performance Mode.
Double click the Power Options in the Control panel.
Click the down arrow showing Show Additional Plans to see the High Performance power plan
Now just activate the High Performance plan and that's it.
Go for the advanced power settings.
Go to Hard disk, then to Turn off hard disk after and set it to Never. This enables the GC to do its job while logged off.
