Another thing to check is the SSD alignment. Here is how:If you are not certain whether your SSD controller supports TRIM, there is an easy way to find out.
Open an elevated Command Prompt (run as admin) and paste this command into the Command Prompt window:
fsutil behavior query DisableDeleteNotify
If Command Prompt returns a 0 (zero), your drive supports TRIM and it is enabled.
If it returns 1 (one), the file system has disabled TRIM for your drive. This means your drive's controller does not support TRIM.
Source: SSD Alignment[/QUOTE]If you want to verify the alignment (e.g. for a SSD where you are not certain whether the proper alignment was done), you use the following commands.
Diskpart
List disk
Select disk n
List partition
Now you should see a result like this.
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 59 GB 1024 KB
The offset has to be divisible by 4.
Hmm, interesting.
Part 1 : Running that command returns DisableDeleteNotify = 0
Part 2 : Diskpart returns Partition 1 - Type Primary - Size 74 GB - Offset 31 KB
