Windows 10: Is it bad if a SSD is too fragmented?

I know this is a old question but I can't find proper answers there and here.
I run Mydefrag (I have it because I have 3 mechanical hard drives) and checked my SSD out of curiosity and it's all yellow (fragmented), seems that at least 80% of all files are fragmented.

I know that SSDs don't need to be defragged because they have way less seek latency than HDDs and shortens its lifespan, but can performance be somewhat reduced in a heavily fragmented file system, I say, Windows needs to locate every file fragment and that needs CPU?

Thank you

If a game is left open but is it paused does it still use data on a windows phone ?

Hi

Your question has been moved by a moderator to the Windows Phone forum for more focused attention by the experts on this subject.

 

If a game is left open but is it paused does it still use data on a windows phone ?

My phone i clicked back which usually closes all games and or apps open but I saw that a game was left open since earlier in the day ?I am not sure how much data it has used and I am scared because I dont want my phone taken away.

Windows just thinks it's fragmented, because the SSD's controller "Lies" to Windows to make it think it's a spinner.
For example, if Windows expects the boot files to be at the outside of the disk, so the controller say's "yup, that's exactly where I placed them(fingers crossed)", but there is no disk, just cells.
So over time Windows thinks the SSD is fragmented, when it's not. Data is always placed in whatever cells are free, until trim is run, then they are place in blocks together, so the controller won't have to search all the chips.

Another words, in short, only the SSD's controller knows where the data actually is.

 

So it's simply how the controller reports to Windows and not the real state of fragmentation

Thank you for you excellent answer *Smile

HDDs (spinners, mechanical) also "Lies" to OS, logical and physical sector placements are not same.

 

Fragmentation is not strictly just about where blocks live on the disk.

Another aspect of fragmentation is fragmented directory entries and the MFT. When these become fragmented, they use up more space than is necessary, and cause extra lookups for directory scans. Thus, over time, it takes longer and longer to find any given file. In extreme cases, the filesystem can actually run out of entries and cause other issues.

This is why the Windows disk defragmenter will, on occasion, do filesystem defragmentation and cleanup on SSD's, in addition to running TRIM requests.

You should only use an SSD aware disk defragmenter, such as the built-in Windows Defrag. It does a fine of making SSD's the most efficient they can be.
