How to tell if TRIM is enabled on my RAID0 SSD?

[Noc]

Hello, I’m trying to confirm whether or not TRIM is actually working on my system and I can’t find any definitive answers.

I’m on a new Asus G750JZ-DB73, which has dual SanDisk 128 GB SSDs in RAID0. I’ve heard that TRIM was incompatible with RAID, but I’ve also seen recent reports claiming that newer drives or motherboards or whatever did allow for TRIM with RAID drives. My knowledge if techese is limited, so I’m unsure what to believe.

Secondly, I’ve encrypted my SSD(s) using DiskCryptor without issue, and DiskCryptor claims full compatibility with both RAID and TRIM.

Here’s where I get confused. Both CrystalDiskInfo and the “fsutil behavior query DisableDeleteNotify” command in Command Prompt indicate that TRIM is enabled on my system. However, when I use TRIMcheck, I’m informed that TRIM doesn’t appear to be working.

How can I conclusively verify if TRIM is working for me? And if it isn’t, is there a way to activate it on my system?

Thanks in advance.

EDIT: The SSD is a SanDisk SD5SE2256G1002E.

“fsutil behavior query DisableDeleteNotify” command in Command Prompt Is your best indicator, if result is 0 you are good to go. If you can force Trim in "Optimize Drives" is also good indication it's working.

For Windows 8.x.x, Trim is automatically enabled. For Windows 7, you have to have sp1 installed to get Trim automatically enabled.
