SSD TRIM on windows 7

P4-630 · Jan 11, 2017

A while ago we replaced the HDD with an SSD in my dads laptop.
I found out now that auto defragmenting was still on, we turned it off.

My dad just installed the Sandisk SSD software and it seems there isn't a manual TRIM function in it.
There was however an option to enable TRIM on windows 7, this option is checked now.

How do I know when it runs and can I schedule this?
If so, how?

Trim is pretty much maintanence free man. It takes like 10 seconds to do a full trim, and trim is executed automatically on file deletes. I am unaware of a means to control this or do a manual full trim in 7.

TRIM works in the background. So long as you have it enabled, it will continue to work behind the scenes. no need to run any program or app to 'defrag' it.

Alternatively, Install 'Sandisk Dashboard' Is Sandisk's own software kinda like Samsung's 'Samsung Magician' and i think there is an option to force 'garbage collection' ahead of schedule.

Yeah I know, it's so easy on windows 8.1 lol!

Yeah my dad installed it today, I talked with him on the phone and told him to find a manual TRIM option in this software.
He will take the laptop with him tomorrow when he comes here, I will look for this force of "garbage collection" option then.

normally trim should work if you let your pc idle for a few minutes.

Ok I'll give that a try tomorrow.

As long as trim is enabled and defragging is disabled you should be fine. There may be some slight benefit to forcing trim, but only if the manufacturer's firmware isn't doing its job properly- most firmware is pretty good nowadays.

Funny, both my Sandisk SSDs had trim set to on and defragging off by default when I first installed them with Win 7. Might be because I have intel rapid storage running?

Well we cloned the Asus recovery partition from the HDD to the SSD , installed the SSD and fired up the laptop and installed windows 7.

Not likely. What OS?

Understand that Windows knows if it encounters a SSD or a HD and will NOT defrag a SSD. This is actually why the feature is called Drive Optimize in Windows and not Disk Defragmenter any more.

The verbiage is a bit confusing but for sure, Windows will not actually defrag a SSD.

I'm going to feel responsible if a rash of these type of threads spring up. When W7 came out, and SSD were still pretty crap, I was running a heavily modified version of the OS with a lot of weird stuff going on. Jump forward to today, and despite forgetting almost everything I knew back then, I have this habit of turning things back on and confirming stability.

The couple of SSD I've installed on W7/W10 were completely plug and play with BIOS and auto-installing drivers making all the correct decisions in the background.

Well it was...
As I mentioned earlier we cloned the recovery partition from the HDD to the SSD , installed the SSD and installed windows 7 after that.

You should know it was about windows 7 as already stated in the thread title.... Not sure how you missed that....

I did see W7. But even W7 was able to detect SSDs. The problem with W7 is that the program used to "optimize disks" in W7 was still called Disk Defragmenter so it caused confusion. It was renamed to Optimize Disks in W8. So as I said, the verbiage is confusing but W7 does not defrag SSDs even though the verbiage may lead users to think it does.

Note in W7, users could force a defrag, but Windows 7 would not defrag SSDs automatically.

See this TechNet article and note the following (their bold):

Defrag cannot be automatically scheduled on volumes hosted by SSD disks

The new Windows 7 Disk Defragmenter will exclude the volumes that are not recommended to run defrag regularly

Note that volumes on SSDs and dynamic VHDs can be defragmented but are not scheduled to run regularly

Anyways , "disk defragmentation" was scheduled to run automatically and I told my dad to disable it. Eventhough it may run or not, we just disabled it.

Bill_Bright · Jan 11, 2017

That's fine but understand when you disable it, defragging on any hard drives are disabled too. If he is not frequently installing and uninstalling lots of programs and hardware AND if he has lots of free disk space, I would not worry about automatic defragging being disabled. It will take many months (if not years) before fragmentation affects performance.

The laptop has only 1 disk with 1 partition which is an SSD now so thats not really a problem.

Bill_Bright · Jan 11, 2017

Then fragmenting is not a problem anyway. But TRIM still is.

W7 has individual defrag settings for different drives

Yes, but that is a manual process. I should have been more clear.
