Intel warranties the SSD for 5 years writing 100G per day. From Anand: " Intel will guarantee that you can write 100GB of data to one of its MLC SSDs every day, for the next five years"
You arent even close...
But you should turn off the useless writes. There are several sites which will help you tune your system for less writes. SSD's are so fast that the other things slow them down and cause useless writes, for example: no defragging, turn it off, turn off prefetching, indexing, turn off the pagefile (controversial, so at least move it elsewhere - mine is off with no issues).
