x79 RAID 0 Trim solved?

post #1 of 5
Thread Starter 
Ok so i updated my drive today to the most current Intel has for Win 8 64 Bit which is rev. 3.5.1.1008 and then ran the command

fsutil behavior query disabledeletenotify

in command prompt and got this

disabledeletenotify = 0

So i think this driver is passing trim across raid 0?

Correct me if im wrong i hope im not though!

Marcus

EDIT: I thinki i just found the answer myself i think all this means is that trim is enabled not that trim is running on the current setup... is this correct?

WRONG: about TRIM.

You didn't update your drive, the only update a drive has is firmware, you updated the controller driver.

Just because windows has TRIM showing as enabled, doesn't mean the drive is getting the TRIM commands.

As for your X79 that is using the RST-E option ROM, NO, your drives in RAID 0 are NOT getting the TRIM commands.

If you open tools for your drive you will see in optimize that your RAID is seen as a HDD and not a solid state drive.

Maybe by the time Ivy bridge -e CPU comes out, that has PCI-E 3.0, Intel will have fixed the option ROM and drivers to allow the
RAID array to read the TRIM commands, who knows how long before they correct it..


As for your edit, windows has TRIM enabled, and is sending the TRIM command, the problem is the RAID array can't read the TRIM command so the drives are not getting TRIMMED.

Most of the newest drives have such good garbage collection, that TRIM is not as important as it once was. OCZ Vertex 4's and the new vector are fine without TRIM.

Along with the disappointment that Intel placed support for PCI-E 3.0 on the older 1155 CPU's but left it out on the newest 2011. Almost as if they did it on purpose to make money off the
sandy-e, then they put out Ivy-e, now they take in money for both.

If you have a PCI-E 3.0 graph card, Nvidia has posted a hack to enable the 3.0 bus. I would get GPU-Z, see that your running 2.0, then run the ENABLER, and check, you should see 3.0.

Not all games will show improvement, for me Crysis 2, showed a frame rate increase of 20FPS. You should check your game frame rates, then install the hack and check again, so you can see if you have any improvement.

Here is a link for the ENABLER.
