I ran GSmartControl on my two SSDs (Ubuntu 14.04 laptop), and I see a lot of pre-fail indicators in the reports (attached). Does this mean I am approaching the drives end of life and I need to replace them?

I have also read that each SSD manufacturer codes the SMART attributes differently (https://askubuntu.com/questions/325283/how-do-i-check-the-health-of-a-ssd). Not sure if this is true today, since these posts are several years old.

I looked at this "dictionary of terms" for Samsung drives (http://www.samsung.com/global/business/semiconductor/minisite/SSD/M2M/download/07_Communicating_With_Your_SSD.pdf). I am confused as to why the values in my reports are considered "pre-fail" or "old age" when many of them are zero.

Can you interpret these reports for me, or point me to some documentation that will help me understand what they are telling me?
