I tried this out earlier, and it wasn't able to give me an estimate of my drive's lifetime because, apparently, it doesn't report that statistic. It did, however, say that my drive was healthy. I'm running Windows 7 Pro 64-bit on a 128GB Samsung 830 SSD, which has been rock solid for the past nine months since I bought it. I'm upgrading to a 512GB model soon.<br>

</div>It most likely won't work under wine as getting that data from the<br>
drive requires sending raw device commands (ioctls on Linux) and I<br>
don't think wine provides an emulation layer for this. (It might, but<br>
the use cases would be pretty limited.)<br>
<br>
My understanding is that smartmontools (at least as of 5.40) supports<br>
SSD wear level indication. Basically, the drive can report what % of<br>
its spare blocks are still available. Read (and record) that over<br>
time, extrapolate, and there's your wear leveling limit.<br>
<br>
That being said, most SSDs that die don't die because they've hit<br>
their write cycle limit. I've personally seen a couple die due to<br>
controller failures, and those drives *completely disappear* from the<br>
system.<br>
<br>
I operate as if my drive will fail any second. I have an extensive<br>
set of backups, and that's how I plan to preserve my data, not by<br>
trying to guess when a drive will fail. (Or be stolen.)<br>
