1. We do not calculate the percentage of the drive health. The SSD itself calculates it and gives it to us. Or in other words, this data comes from the manufacturer of the drive.
2. The estimated lifetime is calculated depending on the amount of data written to the drive. If it is not calculated yet, it means that little data has been written to it. Simply wait a bit, it does not usually take more than a week (or two) after the first launch of the program.

This 179 years business has only been true in the last 2 years or so. For the first 18 months I owned this drive, the figure given was much more typical--between 8 and 10 years, varying slightly from time to time.

My usage pattern has not changed and is so mundane as to put you to sleep, averaging between 4 and 5 GB per day of writes, with little variation.

I'm up to over 180 years right now, for what it's worth. Not much.

10MB? Big, fat, hairy deal. Like that will reduce your SSD life enough to notice. People worry too much about wearing out an SSD. Even the lousier ones are unlikely to die early from too many writes; they are far more likely to die from controller failure. Unless one is constantly writing and deleting huge amounts of data or frequently defragging them, one is far more likely to replace a SSD because technology has left it in the dust than because it wore out due to excessive writes. Even leaving Hibernate enabled will not noticeably reduce SSD life unless one has a huge amount of data in RAM most of the time and frequently hibernates the machine everyday (it will save space, however).

Seriously, the tool is worth having. The free version tells you how much has been written to the SSD, if TRIM is enabled or not, the number of hours the SSD has been used, the number of starts it has (granted, there are other ways to get those SMART attributes but it is convenient to have these in one place), and the percentage of health based on SMART attributes. It's not a tool one will need to run daily. Even running it once a month is excessive, needwise.

The program itself is only 3.37MB in size, which nowhere even close to being a concern for size, so it does no harm to have on one's computer.

Yes,I disable it the same day I installed the windows and reduced the pagefile to 1gb(I use Process Hacker as task manager replacement and he have a feature to show me how much of the file is used and peak usage...I've never see it displaying anything other than 0).

I only place things on the ssd which I need to be there...all else is first on the ram drive,then if I need it,I place it either on the ssd or the hdd(depending on if I need it to be on the ssd or the hdd))

I think i need to mark sarcasm better... i know 10 MB is not much compared tot he 5.44 TB I already wrote. I think 99.99% of SSDs that have died so far died of controller failure, bugs (I'm looking at you OCZ!) aand other electronic failures. NAND wear is not a major SSD killer. (I'm curious if HDD have some limit on writes... i assume you only can magnetize a part so many times?)

Anyway, this tool still is useless. Besides the lack of need to fear NAND wear, it doesn't give you good data. SMART isn't really good at predicting life of HDD or SSD. The manufacturer tool does a better job. When I read above about 179 years predicted life.... i may as well spin a bottle to "calculate" the remaining life. and for my 2 year old it showed 100% health. great, so my SSD did't wear at all in 2 years?

And what else does the tool give us? the number of TB written so far.. the manufacturer tool does that too. It also tells me what is enabled, what should be enabled and actually makes those changes in OS (at least Samsung Magician does it)

To each his own, if you like the tool, fine. But I de-installed it after the first try after seeing how useless the numbers are.

Samsung Magician does NOT tell you if TRIM is enabled or not, which SSDLife does.

After reading this > Introducing the SSD Endurance Experiment - The Tech Report - Page 1 I stopped counting and worrying.

the SSDs in my main desktop have logged less than two terabytes of writes over the past couple years. At this rate, it'll take me a thousand years to reach that total.

because W7 enables it by default. you can check

In XP times I installed every available tool to optimize or verify OS operation since XP didn't really have much built in (and I wasn't as knowledgeable). now I use W7 tools as much as possible to avoid having all these "free" tools installed.

Not everyone can remember commands, especially rarely used ones; I certainly can't. It's much easier for most people to have a utility to do it for them. Also, TRIM doesn't always get enabled, even though it is supposed to (and usually does), so it is a good idea to check a new installation and recheck every once in a blue moon.
