Re: Buggy Intel SSD 520 Series SSD Firmware said by trparky:I thought that TRIM was supposed to be done even if Windows does it itself. I know that Windows performs a TRIM when you delete files but what about when you overwrite a file?
Microsoft hasn't exactly been very forthcoming with their policy on the TRIM command that's built into the OS. When does a TRIM happen?
It "should" be.
Here's a way to check if it's enabled.
Open a command prompt, (Administrative level).
Command prompt > fsutil behavior query disabledeletenotify
DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled) |

Overwrite doesn't happen with NAND flash. it must be deleted and written in other blocks...
Here's a nice article that might help explain the difference between TRIM, and Garbage collection.

Due to wear leveling you don't ever overwrite
overwriting nand is very slow and time consuming so instead it writes to a new location and marks the old for GC to clean up
