    Question About Defragmenting An SSD


    So every time I open up Defraggler, I see so much fragmentation in the main drive, which is an SSD.
    I am already aware that defragmenting an SSD tends to shorten its life over a period of time. Yet when you "Optimize" an SSD, isn't that doing a same amount of harm on the drive itself anyways? Because when you "Optimize" an SSD, you are writing to all the empty sections of it anyways. So If I defragment the SSD, there would be a bit more activity compared to "Optimizing" it, since I that would be moving a file from one section to the other.

    I am also aware that it is completely unnecessary to defragment an SSD. The only reason why I would like to defrag my SSD is because it looks so messy in Defraggler. I won't be defragging it every day or whatever, but maybe once every few months, or when it looks sooo messy (as you an see in the picture).

    So it's okay to defrag it (not optimize it) once every few months or so, correct?

    Cute signature!

    Might want to read some of the pages at ssd trim at DuckDuckGo about TRIM and SSDs.

    That search engine is specifically designed for my avatar picture. hah.
    And yes, funny signature... it's actually more complicated than it actually is, as a matter of fact. (Hint: look very closely at it; use your mouse as a precise guide)

    And yes, TRIM is what "Optimize" does. (Strange how TRIM isn't automatic when you delete a file, since whenever a new file needs to be written, Windows has to TRIM that section of the SSD before using it anways)

    So Defragmenting, then Optimizing, an SSD isn't really doing much harm at all anyways? Correct?

    Haven't concerned myself with defragging since the fall of '09 when the intel x-25 arrived. Having said that, the i immediate risk of shifting 10's of thousands of files around is greater than the long term harm done by defragging regularly given the petabyte plus lifespans of ssd drives.

    Never defrag an SSD! All you're doing is reducing its life. In this case 3rd party tools are useless. Let Windows 10 optimize the drive as needed.

    theok: I never thought of it that way. That does make sense. SSD moves many files at such a fast rate of time. So physically speaking, errors could possibly happen. Is there articles that show this can possibly happen?

    vram: I'm aware of what you said.

    I've used similar when trying to screw with a friend's mind.

    I don't worry about the SSD but only have them on a couple of Tablets and one HP Notebook running Linux Mint 18.1.

    CDO - it's like OCD except in alphabetical order the way it should be!

    You can use the SSD the way it was designed to be used which is efficient, gives maximum life, and reduces chances of data corruption.

    Or you can insist on turning all the little squares the same color, with no improvement in efficient, shorten the life of the SSD and increase the chances of data corruption.

    But, honestly, if it makes you feel better and increases the enjoyment you get from your computer then go for it! Sometimes our peace of mind and happiness is worth paying for. I admit, it is kinda fun watching the little squares all turn the same color, and it goes so much faster with an SSD than the old spinner!

    And the reason the SSD doesn't do trim when it empties a data storage location is because the exact moment that location is emptied may not be the most efficient time to write the reset command. There may be other files waiting to be read or written and the SSD can only do one data manipulation at a time.

    I've never been tempted to defrag an SSD. Defrags were beneficial in the old days of HDD's, as the heads were slow and having to get to file fragments in 20ms each really slowed down the box.

    in the age of SSD's, they can access the same fragments in 0.1ms with no moving parts.

    So, who cares if files are fragmented. You would never see the performance hit. But if you defrag the drive you certainly will use up a certain portion of your total writes.

    I too started with an Intel X-25M G2. I've had it now since around 2009. Still going, no issues.

    According to Microsoft, Win10 does defrag SSDs once a month as part of Maintenance. It doesn't move the data on the SSD around, but it does defrag the Windows file tables, as there is a limit to the number of fragments that a file table can hold.
