SSD Wear Level Monitor Utilities

[BillW50]

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.

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. ;-)
