Lots of SSD Activity after removing Several Gigs of Data

[Ketchup]

I just want to make sure this is normal (this is the rig in my sig). I was copying some files across the network, so once I verifies they were moved properly, I hit delete and empty on the recycle big. Probably 10 GB of data or so.

A few seconds after, I had 15-20 seconds of sustained drive activity. Couldn't really open anything new (the mouse was fine) until it was done. Afterwards everything was back to normal.

I have a laptop with an SSD, but never moved stuff around like that. I have seen this a few times on the desktop.

So, what say you all? Do I need to ask Crucial to have a look, or is this how these drives operate (I am about a year with SSDs)?

Thanks in advance.

I've never noticed anything like that, in Win7 64-bit (240GB M500) or Linux Mint (80GB X25-M G2).

The same used to happen to me when using Crucial M4, I assumed it is TRIM working by zeroing deleted data.

some times it is unnoticeable, just you can see spike in disk activity for few seconds after delete.

It's somewhat normal. The drive was doing garbage collection after a TRIM command was sent when you emptied the recycle bin. Garbage collection doesn't normally take very long though. If it had been a long time since you emptied the recycle bin I guess it could take a while.

Thanks for the comments. I was actually wondering if it had something to do with TRIM. Hopefully that's all it is.

Had a few crashes with the drive here and there, but I blamed the old sata cables I was using (probably 5+ years old, being moved from here to there). Since I put a new sata cable on it, it has only rebooted once.

This slow down happens with hard drive as well. The drive seems to do something, although it is only clearing the MFT off the index and marking them as free. You can use shadow explorer to get the files back if you have system restore turned on and windows does not write anything to the areas the deleted file occupies until it runs out of free space. Some programs can defragment the MFT.. Since windows will store small files in the MFT itself, it can grow to a large size with a lot of files. I dont think TRIM will do house keeping immediately.. The drive does that when it is not busy and you dont get to see it.. On a 100GB drove, the MFT can grow very large to over 1GB of 4K clusters.. Once due to a bug I had a few millions very very small files created which created an MFT of over 50GB and it took half a day to delete it. Yes over 12 hours.. I complained to the company about their program so they deleted my account. lol Thats one way to get rid of a bug..

I have seen this as well. As near as I can tell, it involves consolidating white space, which, I believe, is a part of garbage collection and TRIM. You can expect a lot of that if and when you are satisfied with Win 10 and wish to get rid of the old OS using Disk Cleanup. I did that on a HDD yesterday and got rid of hundreds of gigs. Of course, that gets rid of any reversion, but, I don't need that since I have other backup drives. I may try it on my laptop today, and it is all SSD.

Also, when Cleanup removes the Windows.old, it also cleans up all of the hundreds of Windows updates tied to that OS.
