I almost fully disagree with everyone.
Yes, I agree with: how more writes and stuff, decreases your lifespan of SSD
But, a big BUT
- people recommend also, that you don't move your internet temporary folders and cache folders, from SSD to an HDD. Why ? I don't understand.
Every site you view creates new cache files on your ssd. Then you use a tool like CCleaner to remove them again. That's a lot of writes done on your ssd.
Now we are getting to the point: Never do a defragmentation on your ssd.
If you never do it, like me in the past, what are the results ... ????
Your SSD is so heavenly fragmented, that it slows down your windows startup. I've seen it with my own eyes.
In the beginning startup time: 17 seconds. After a few years: 45 seconds and increasing !!!
Even my READ and WRITE gets slower.
From that moment on, I've decided to defrag only, the fragmented files. (so not everything)
Only what's fragmented. Free program "Defraggler" has this option: by selecting the fragmented files.
I did a reboot of my pc after that = startup time => 18 seconds again !!! Yes: one second less, but I've installed many new things also in all those years.
End conclusion: Do only a defrag on the fragmented files, 2-3 times a year.
Specially if your cache temp internet files are also stored and removed on your SSD.
Do you really think, that those 2-3 times will make a huge impact on your lifespan ? While daily read and write: internet files.
This question is a dupe. I have also said this before as well... There is no point in defragging a SSD, since SSDs intentionally fragment their data for wear leveling. – Keltari – 2014-10-02T19:35:36.460
In short, SSD will still suffer from fragmentation. But SSD will also suffer from moving of files on the process of defragging the SSD. SSD has a write cycle limit, so the more often you write / rewrite into the SSD, the quicker it is to degrade the SSD. SSD is pretty fast as it is, so even in a fragmented condition, it may still outperform normal HDD without any fragmentation. (May. Testing is required) – Darius – 2014-01-01T10:50:41.733
