is TRIM actually working for me?

I have an SSD and I did the steps to activate TRIM.

Quote : 1) Check if TRIM is activated fsutil behavior query DisableDeleteNotify If you receive a result of 0 then TRIM is enabled, and if you get "1" then the TRIM command is disabled.

My command prompt shows a value of 0 indicating that TRIM is enabled however I just opened up Hard Disk Sentinel and it says TRIM is supported but disabled. So which is it? Is the program wrong? My command prompt? The article goes on to say

Quote : Being told that TRIM is enabled does not mean that storage drivers pass the command successfully to the storage controller IC on the SSD. Easiest thing to check that this works is to test a benchmark program like ATTO and CrystalDiskMark and compare the data with what your disk is capable of. Do this on a regular basis to see that the numbers are alike. Please note that dont expect to get the maximum out of your SSD drive, the performance will fluctuate but compare it with the general stats of the Solid State Drive.

My crystal disk marks are: (OCZ Octane)

These marks either equal or surpass what NewEgg lists as what should be expected.

Hard Disk Sentinel checks the real usage of TRIM for each appropriate devices (one-by-one). If it displays "disabled", it means there is a problem with the driver of the hard disk controller (if both the OS and SSD should support TRIM). Usually updating this driver from the may help. If not, using a different hard disk controller
may also helpful.

This is true even tough the other shows TRIM working... right now TRIM is not working on your system.

Hard Disk Sentinel doesn't have octane on their tested SSD list:

OCZ has a working forum. It would be a better source to get your answer there.

You should probably post the model number of your octane drive since there is more than one 128GB octane on newegg page.

Heres my Crutial M4 64GB result....

The status of the solid state disk is PERFECT. Problematic or weak sectors were not found.
The TRIM feature of the SSD is supported and enabled for optimal performance.
The health is determined by SSD specific S.M.A.R.T. attribute(s): #202 Percentage Of The Rated Lifetime Used
No actions needed.

Here is the exact drive I have

Now that I look at those specs, my drive is performing a little less.

The page says TRIM SUPPORT The Octane SSDs feature support for the Windows 7 TRIM command. This allows them to store only the data they need and perform memory optimization to ensure the fastest possible write speeds.

I'm using Windows 7 professional 64bit so both the drive and the OS support the feature.

The Octane itself is not on the list but it does list Indilinx Everest which is what the Octane uses so it should be supported right? I'll have to find the OCZ forums later on to see what they say about TRIM

I think you are finding out why everyone pretty much says choose Crucial, Intel or Samsung when it comes to SSD quality
