Do the Intel(R) RSTe drivers v3.0.x.xxxx support the Trim command?

[DZand]

Owners of an X79 chipset mainboard need to use the new Intel(R) RSTe drivers (actual version: 3.0.0.2003 WHQL) instead of the RST ones.

Since the Intel(R) RSTe drivers of the v3.0 series do handle the SSD's as "SCSI Disk Devices" I am wondering, if these drivers really pass through the Trim command to the SSD. This question is only valid for Win7 systems running in AHCI mode.

Thanks in advance!

As per the http://www.intel.com/support/motherboards/server/sb/CS-033344.htm RSTe for Windows* Software User Guide, TRIM is supported in a non-RAID configuration.

Edward,

I can post a screenshot that Optimizer button is greyed out for Intel 520 driver w/RSTe drivers for Win7.

Or you can take my word for it...

You're referring to the SSD Toolbox right? I haven't tried it with RSTe myself, but if it's in RSTe passthrough mode then the native Win7 TRIM command should get through the SSD, thus you don't need to run TRIM from SSD Toolbox.

That is correct, I'm referring to SSD Toolbox. I understand the theory and hope it works the way it should, however what I don't understand is why Intel products - drive, driver and Toolbox are not compatible with one another even though they theoretically should.

From my experience if something doesn't work as it should in one respect it might as well go sideways in others - so this pass through idea gets questionable also. After all, there is a reason for Optimizer button to be greyed out as it is, right?

The only hope is that fsutil command returned 0, so in the end I'm getting mixed messages.

BTW, I've opened a ticket with Intel couple of weeks ago, however no resolution on the horizon.

Really disappointed with all that - the above mentioned products been around for a while now and Intel should (again, in theory) pay more attention to QA so half baked SW doesn't get into production the way it does now.

try running the trimcheck utility to see if trim is actually working.
