SSD lifespan

[theweirdguy14]

So I was defragging my SSD, then I found on the web that defragging your SSD will reduce its lifespan I was using the Auslogics Disk Defrag Pro. I stopped it at 5%, I'm worried about my drive I checked it's health in crystal disk info and it says 100% Correct, should I be worried about its life span or it will not reduce because I stopped it at 5%?

1. Don't worry, you're fine, 5% or even 100% made once do not reduce lifespan of your ssd. But don't do it again.

2. Don't try to improve things too much. If something works fast (in SSD case mostly as fast as possible) - leave it that way.

3. SSD lifetime is very long. Well, maybe not very long, but after 3 or 5 years you'll have probably completely different drive and forget about current one.

Most defragmenting tools will not defragment SSDs.

 

SSDs don't need defragmenting, because they intentionally spread the data around so that when it has to be read, then the controller inside the SSD can read chunks of the data you need from multiple flash memory chips in parallel and get more speed this way.

With mechanical drives, it made sense to defragment a drive so that the data is arranged sequentially on a disc track, because the most time wasted is for the hard drive to move the read heads over that track, and then that track is read as the disc inside the hard drive spins.

 

You don't want to defragment SSDs because it's pointless and because a SSD has a finite amount of writing over the course of its life... for example, most modern 1 TB SSDs are rated for up to around 600 TB of data being written to the memory chips.

When you're defragmenting, the application pointlessly tries to copy chunks of data from one location to another on the ssd, so you burn through that  "lifetime writes" budget.

 

Anyway, you don't have to worry about it ... the application probably wrote 10-50 GB of data to the SSD, and you still have hundreds of TB of writes available. It's a drop in the ocean.  By the time you reach the high number, it's gonna be 5-10 years or more, and you'll laugh about the 1 TB ssd when you can buy 10-20 TB ssds from the store.

Thank you so much for your answer I won't do it again

No worries, no damage done.
