Windows 10: Windows Defrag schedule / SSD maintenance query

Thanks for the information. I just came back to this thread to respond and saw I had loads of replies, it didn't notify me even though I set it to do so!

Anyway like you I did a bit of an experiment - I noticed in Windows Defrag (or Microsoft Drive Optimiser as they now call it) that it was as high as "10 days since last run" even though as I've already said, I have it set to optimise weekly. I did wonder if it was one of those random Windows things where it needs to be on at 3AM in the morning (a lot of scheduled operations in Windows are like that, and the chances of my laptop or PC being on at that time are pretty much zero so it's kind of pointless!) so last night I decided to leave my laptop running all night long, thinking maybe it will kick in the defrag schedule and optimise the drive during the night. But no, woke this morning to see it still saying "10 days since last run", and I've never been notified of any "missed runs" despite that option being ticked in the defrag settings. Also like you say, the Recovery partition also says "Needs optimisation" always, yet you can't do anything with it.

So long story short, basically I am going to have to remember to come into the defrag app every week or so and click "Optimise"?

 

I think it depends on the manufacture. I have a couple of Samsung SSD's and they explicitly state that Defrag should be off. The reason being is that they supply a software component "Samsung Magician", that optimizes the drive and I assume it performs the trim function when required.

 

I still can't understand why does defrag utility needs to TRIM SSDs when TRIM is enabled?
Does this means that TRIM isn't always sent when deleting files?
In my case it sometimes says Needs optimization

 

Hi,

Defragmenting is used for HDD, not SSDs.
Optimization is sending a RETRIM command. It will say "Needs Optimization" for a number of reasons one of them being that the machine has seen not enough idle time for the OS to optimize the SSD in the background.
Another being that optimization has not been run yet on a new drive or volume for instance.
