Defrag windows 10 pro


I posted before about whether or not to defrag b/c I read that with an SSD you do not need to do so as windows handles it.
Does this mean you turn of the optimize /defrag feature or set it to one month for example?
If off, the implication is that windows will override this set up feature and do so regardless and on its own.
So, type opt in search and when optimize appears, turn feature on or off?


No need to defrag an ssd since all items are equally accessible unlike a mechanical drive.


Do NOT turn off the Optimize tools for Windows 10.

SSDs still require optimization under Windows 10, but they need a different kind of optimization.

Where hard drives need defragmenting, SSDs need TRIMming and wear leveling. These are very different tasks, but they serve some of the same purposes.

Defragmenting re-orders the data on a hard drive to keep files together, whereas TRIM on SSDs is used to pre-erase certain blocks to make it faster to write to previously used sectors.

The Optimize tool in Windows knows the difference between a hard drive and SSD, and it will automatically perform the correct optimization for each drive. So you should leave it enabled and allow it to run on its normal schedule.


Thank you for your help.


SSDs don’t just eliminate moving parts and improve access times, they also have built-in wear-leveling algorithms. The reason is that the NAND gates wear out over time, and are rated in program/erase cycles. Each cell in a modern SSD can be written between 1,000-3,000 times before the cell stops working properly. To avoid individual cells that contain frequently changed data from wearing out faster, SSDs track usage of each block, and the wear-leveling algorithms ensure that over time, the cells on an SSD are written a similar number of times. There are also extra blocks that aren’t user accessible (called spare area) that the algorithms can use to keep the drives from wearing out.

Because of the way SSDs work, not only does data not become fragmented, but running a defragmentation utility will actually burn through the program/erase cycles and potentially cause premature ‘death’ of your SSDs. It’s not something that would happen quickly—a 500GB Samsung 850 Evo as an example is rated for 150TB of total writes, or the equivalent of writing to every block of the drive at least 300 times. With typical users writing less than 20GB per day on average, it would require more than 20 years to burn through 150TB of writes. But defragmenting could easily write hundreds of GB of data, which would wear out an SSD much faster.



In reference to the Windows optimize defragment feature, and with your extensive knowledge, would you enable to optimize once a month or turn off.
Off = no trim or not?
Thank you
