SSD Wear Level Monitor Utilities
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. -- Bill Dell Latitute Slate Tablet 128GB SSD ('12 era) - Thunderbird v12 Intel Atom Z670 1.5GHz - 2GB - Windows 7 SP1 and Windows 8 |

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. ;-) -- Bill Dell Latitute Slate Tablet 128GB SSD ('12 era) - Thunderbird v12 Intel Atom Z670 1.5GHz - 2GB - Windows 7 SP1 and Windows 8 |

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. Paul |

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. ;-) http://www.csee.umbc.edu/~squire/images/ssd1.pdf -- Bill Dell Latitute Slate Tablet 128GB SSD ('12 era) - Thunderbird v12 Intel Atom Z670 1.5GHz - 2GB - Windows 7 SP1 and Windows 8 |
