    Anybody using these? I have tried them in the past, but all of my
    previous SSD are on Asus EeePC and they don't work on them. Although I
    have been playing around with two Dell Latitude ST with 128GB SSD (eSATA
    drives). I am also a paid user of AnVir Task Manager. And it comes with
    a open source utility called "Open Hardware Monitor". And one of the
    things it reports is the wear level for SSDs.

    http://openhardwaremonitor.org/

    What impresses me about this utility is how small it is. Sure I have
    other utilities (some that costs lots of money) that gives more
    information and allows adjustment of some settings. But this one gives
    me all of the information that I am interested in real time.

    So my question is for those who monitors their wear levels of their
    SSDs, how accurate does "Open Hardware Monitor" compare to others that
    you are using? And how much does does your SSD drop overtime? I am new
    at this wear level monitoring and one reads 91% and the other at 88% and
    neither have budged at all so far.

    Oh I see where it is reading the wear leveling at. For Samsung, it is
    attribute 232 from SMART. I have SSDs from 2007 and I checked one of
    them and that one reads 99% left. Nor am I surprised. As I tweaked that
    XP system to write as little as possible. And I got it down to about
    20MB per hour of normal use. Also these are SLC SSDs, which I believed
    it would take like 4,000+ years to write to every cell 100,000 times at
    that rate with average use. ;-)

    Since people have seen that parameter *increase* after a Secure Erase,
    I wouldn't take the value too literally. It's not computed the way
    we think it is. As users, we would expect percent lifetime to
    constantly decrease with time, but apparently it doesn't work that
    way.

    Yes so true. Although here is a PDF that I just read through and found
    it so very interesting. And using the formula at the end of the
    document, this MLC SSD 128GB is expected to last over 300 years if I use
    it daily. To me quite honestly, most of us shouldn't have to worry about
    wearing out any SSD anytime soon. ;-)
