Defrag doesn't damage anything. It simply just rewrites data.

Your issue seems to be a known bug (unknown to me till now). Check the second post here: http://answers.microsoft.com/en-us/windows/forum/windows_cp-performance/windows-8-automatic-maintenance-defragments-my-ssd/ac52d21c-a6c9-48de-9f22-27af6d23cf00?page=2

Simply uncheck your SSD from the list if drives and run it manually whenever you like.

Alright, well I guess it's good I was poking around making sure everything is where it should be. Do you have this bug too?

Thanks for this Sean! I ran it on both my ancient Vertex Turbo 30GB and my newer Plextor M3 and both work. Great little utility.

Interesting...I wonder...do you Windows guys have a bunch of devs/programmers/etc say that there's no way to check TRIM because the location of information is handled by the SSD entirely (horrible simplification i know)? Because there's been methods to "check" in Linux and they always get attacked with that comment.

I have seen this bug on two Windows 8 installations, on different PCs. My situation is different than what you are experiencing, with some curious results. This is what I see:

  • Single Vertex 4 SSD seen as a SSD in Optimize, and TRIM is run on it.
  • Two Vertex 4s in RAID 0 (not an OS volume), Optimize sees it as a Hard disk drive, and shows a % fragmented. When Optimize is clicked, TRIM is run, not a defrag.
  • Single SanDisk Extreme SSD seen as a SSD in Optimize, and TRIM is run on it.
  • Two SanDisk Extreme SSDs in RAID 0 (not an OS volume), Optimize sees it as a Hard disk drive, and shows a % fragmented. When Optimize is clicked, TRIM is run, not a defrag.
  • Two Intel 520s in RAID 0 (OS volume) seen as a SSD in Optimize, TRIM is run on it and completes successfully.
  • Other SSDs I use (Samsung 840 Pro, 830s, Intel 510) are seen as SSDs in Optimize.

When an Optimize is run, I can see the message, "x% trimmed", even on the SSD RAID 0 volumes that are seen as HDDs. I'm sure it does not say, "x% defragged".

Cugini, you are sure that a defrag is run on your SSD? I'm not saying that it isn't, but just saying you have seen the progress message saying a defrag is being run. Mine clearly display x% trimmed, so I guess I'm lucky.

To clarify: They are both done on the very same Marvel controller, on the very same port. Only the drivers are being swapped and the results are fairly...well...vastly different.

Below are the results, both checking for AS SSD benchmarks and a tool to check if TRIM is working on the drive.


Microsoft AHCI Drivers:




Marvel 91xx Sata 6GB/s Drivers:



As for my personal experience. The Marvel drivers offered incredibly slow boot times and a very buggy feeling, where as the Microsoft drivers were stable, faster and offered a blazing fast boot time. Both, however, support TRIM.

That is a really bad showing by the Marvell driver, even worse than previous Marvell drivers. That result with a 256GB 840 Pro too, very poor to say the least.

And just to clarify, it's only defragged when windows 8 automatic maintenance is running.

As soon as I saw the SSD labeled as a HDD, I turned off the automatic optimization.

So it makes a difference if it runs automatically or manually? Right now, I don't know of a fix or workaround for this issue.
