There is a great bit of free SSD software for your computer that tells the health of your SSD etc..
Ran it on my desktop with a ocz vertex SSD and says mines good until 2023..
Think it is called "SSD life"
Also most SSD manufacturers have their own SSD tools to keep your drive in good health so search them out as they help extend the life of your SSD..
Also you need to enable ACHI mode in bios to enable trim support..so check your set up.
Found this May be of help..
This tutorial is for those who are already running Windows 7 on their SSD as a boot drive. If like me, you first installed to hard drive then used an image backup program to put the OS on the SSD, then this step is necessary to allow Windows 7 to set the proper settings for SSD use and set things up for optimizing the OS after burning the firmware and/or cleaning the drive to factory specs. If you installed directly to the your SSD, you don't need to follow this step, but it can be helpful if you followed the XP and vista SSD guides and things just aren't up to snuff.
*** read all the steps first so you can create the images and boot USB and CD/DVD and print the instructions before you start***
FIRST.... MAKE A BACKUP IMAGE just in case!!!!!!!!!!!!!!!!!!! Be sure to create the restore disk, too.
Basically, you need to do a repair install of Windows 7 so Windows can set itself up properly for SSD use. The following link will step you through this step:

When done, we need to verify that TRIM is active. At a command prompt (start/run/cmd), type the following: fsutil.exe behavior query DisableDeleteNotify
It should respond back with DisableDeleteNotify=0 if trim support is ready and active. If it is not, type fsutil.exe behavior set DisableDeleteNotify 0
This will set Windows 7 to use TRIM when the drive and drivers are ready to do so.
Next, we need to make sure our ATA/ATAPI ACHI controller is set to use trim.
The new INTEL chipset drivers 9.6.0.1014 support TRIM! Use these instead of the MS AHCI ones for Intel Chipsets.

If your controller chipset does not support trim then use the MS driver.
To see/change it, go to device manager and select IDE ATA/ATAPI controllers. If it says "Standard AHCI 1.0 Serial ATA Controller", you are good to go. If not, double click it and select the driver tab. Click update driver. Select browse. Select let me pick. select Standard AHCI 1.0 Serial ATA Controller.
Once it has reboot and all is fine, then U can go on to the next step (after making an IMAGE backup of the whole SSD with the new changes (I use Windows backup)).
