Just upgraded my PCs SSD

Actually, he's not. :) SSD memory cells can only handle so many writes - a lot of them, but there is a limit. See this: SSD reliability in the real world: Google's experience | ZDNET[^] with that in mind, the controller on the SSD (as well as any other persistent silicon storage) does the job of wear levelling. Because this controller exists, we no longer need to defrag SSD drives. Eventually, cells on the device will fail, and the controller marks them as bad and doesn't attempt to use them. Years ago, when I converted to SSD, I dug into this area, as I was skeptical about how long an SSD would last. The math I worked out was something like 8 years, longer than the life span of the laptop.

Nice explanation! :thumbsup: I did the same research when I bought my first, and that's why I got a 1TB SSD for OS / Apps and (still) use a 1TB HDD data drive. It also reduces the amount of data I need to backup, which helps.

As far as I am aware, the laws of physics haven't changed in the last 7 years. The detailed numbers may be different (hopefully better) with improvements in processing, but the fundamental principle remains. SSD cells wear out. The controller does a good job load levelling. But eventually it runs out of good cells.

It does have an M2 connector, but Im wondering if it is advantageous to put the operating system on that one. Or does that not matter? More is more when it comes to storage :laugh:

Oh yes... It is a boost on speed. Moving data faster is something I wouldn't miss that much, but other things that require reading / writing (i.e. compiling) is a noticable difference.
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

And at least as they fail, you can monitor the "quality" and replace in good time - they don't (generally) have the "catastrophic failure" mode most HDDs experience.

Steve Gibson, being the nerd that he is, also did the math a few years ago in an episode of his [Security Now](https://twit.tv/shows/security-now) podcast and came to the conclusion that yeah, it comes down to many years, but that's assuming you're rewriting all of your free space non-stop, 24/7. For real-world use, I forget the details and his exact parameters, but it came down to many decades, but that was still with unrealistically high usage patterns.

From 120GB to 480GB. :jig: Lots of space now. The old one had ~20GB left, with most of the used space being Windows. New one has 350GB left.
What do you get when you cross a joke with a rhetorical question? The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism. Do questions with multiple question marks annoy you???
what is the brand of your SSD?

And *that* is a valid question. There are a lot of gray market stuff out there, so I don't hesitate to go straight to Samsung for my NVMEs. Do NOT buy their appliances. Just trust me.

the article was referenced for general results, don't be such a hard a$$ :). I doubt google's data farms have changed that much from hammering the crap out of their hardware. Seriously, I support embedded hardware that has been in the field for decades. One of the issues we have to worry about is wearing out persistent storage like this - much smaller but the same concept. When I was thinking about moving to SSD, one of the gripes was that when the SSDs failed it was instant as compared to spinners making noise. With that said, I've been using SSDs since 2010? Heck at least a decade. SATA, m.2 and higher. None have failed. I think it's far more likely to lose your system in some other way.
