Samsung 840 SSD 120GB Wear Leveling

I got myself two of these SSDs 2days ago, and installed them onto two different computers. But just after 2 days, I noticed that one of them is showing 2 on the wear count, and the other is showing 3. From my understanding its basically the wear indicator of the drive. But after just 2 days, i already wore out 3% of it?! Granted I did a full format to check for bad sectors, and installed Windows 8 twice, but still....I know the 120GB 840 is supposed to have a life span of about 3.5-4 years, but at this rate, it's going to last nowhere near that. And since both of my drives are doing the same thing, it's highly unlikely that its due to a defective product..
Do I have an wrong understanding of that wear indicator?

And also from SSD Life, it's showing that I already wrote over 300GB of data to the drive, although I only got it for 2 days...
So I checked to see what's causing the writes, and indeed, my windows 8 appears to be continuously writing to disk even though the OS is completely IDLE. No updates, no installs, no downloads, no nothing...just sitting at the desktop. And I already disabled indexing service, hibernation, superfetch, and page files. I looked in resource manager, and it's all system services, like NTFS logfiles etc. And in the 3 hrs of power on, I have already wrote over 3GB of data. Is this normal at all?! I used to never care about such things when I was using HDD as my main boot drive, but now I'm kinda forced to care since SSD life is limited...

Samsung SSD 840 uses TLC NAND, which wear out fast than SSDs with MLC NAND, however what you´ve described is not normal -- Samsung Magician Software can help to tweak it as stated above.
