Corsair Force GT poor write performance

I bought my 90GB Corsair Force GT about 2 years ago. Originally I was using a Sata II moterboard and if I recall correctly the read and write speeds were around 115MB/s when benchmarked using Crystal Disk Mark as well as AS SSD Benchmark. I just assumed the lower speeds were due to the limitations of Sata II. However when I upgraded to a new MB with Sata III ports the read speed went up to about 460MB/s but write speed stayed at about 115MB/s. I upgraded the MB about a year and a half ago but since the SSD hasn't given me any problems I just figured it didn't matter. Recently I decided that I would finally try to figure out what is wrong with it. I have reinstalled Windows on the drive a handful of times and I made sure to secure erase it. I think the program I used is called Parted Magic but I may be wrong. I recently found out about the Corsair SSD Toolbox and I have been using it for the TRIM command. I also saw that there is a firmware update available but I haven't bothered updating it. I plan on using the Secure Wipe tool in Corsair SSD Toolbox and reinstalling Windows eventrually and I figure I will update the firmware then. Has anyone else had a similar problem to this? I'm not sure what the problem could be since it has been this way since I purchased it and the speeds haven't changed at all really accept for when I got a new MB that had Sata III ports. I made sure the Sata ports are set to AHCI mode (I think that's what it's called). I have never defragmented the SSD. Any help would be greatly appreciated. Hopefully it's something simple that i'm overlooking.

I tend to leave my PC on 24/7 and that's why the Power on Hours count is so high. I do restart it occasionally but it hardly ever goes more than 12 hours while being turned off. Also I used to record alot of videos on the SSD and that's why the Lifetime Read/Write count is high.
