I am new to SSD world, I have limited knowledge about them, and that is - more often you write small data, they wear out faster. So Is having game on ssd and thus saving replays on ssd is bad for ssd or am I misinformed?

Bad for SSD I would say not.

I have WoT on one now for 1 year never had any issues and yes I save replays, must delete them at some point especially the pre 1.5 replays...

Yes SSD have a limited number of writes to each location but this was only an issue in the early days.  A modern SSD will try to ensure the writes are spread around the drive.


Besides, you are talking tens or hundreds of thousands of writes.

I run WOT on Kingston SSD for more than 5 years, no problem whatsoever. Health is still at 100%.


So don't worry about it.

I have the game on an SSD drive and it did concern me a little.

Though given almost everything else is writing to that same drive enails browser and so no.


Thing is I installed the common test on my D drive a standard type HD the Sandbox is there too and I cannot say I see any difference in start up or game performance.

As said, this isn't really an issue with modern SSDs. Those are designed to handle writing over 100 terabytes of data, and in tests individual models could even handle several petabytes. Unless you reinstall WoT on a daily basis you won't even get near those figures within five to ten years.

The problem you mention "more often you write small data, they wear out faster" refers to workloads where files are updated constantly (like multiple times per second on a 24/7 basis) which can happen with some server workloads, but is practically a non-issue with consumer systems, and definitely not WoT replays.


"Small files" are actually more a problem of mechanical disks as they lead to increased fragmentation and therefore worse access times.

Let's take this guy's test:

He has around 200MB/s write speed for 1GB

Take the info from neweggbusiness for Samsung's 3d NAND at about 35000 cycles as reference (which is what i currently feel is the best choice in regards of NAND vs space, speed and cost) and calculate with a 250GB SSD that probably most home users will get.

Which is like 6GB/min which means about 42 minutes for one complete rewrite.

42*35000=1470000 minutes. Which is about 2 and a half years of continuous rewrites for the entire amount of 250GB. And that will not happen in any type of normal use. That's like 250GB*35000=8750TB. What are your weekly downloads, installations, whatever you would save on your SSD? 500GB? 1TB? I would say unlikely. And at 1TB every day you would still need like 24 years to break your otherwise fine working SSD.

So by the time your healthy SSD will naturally die is more than likely you already forgot ever having it. Thus if you really feel like hoarding WoT replays, you can safely store them on your SSD.
