To make it official though, Dan Snyder, PR Manager of Intel Corporation, can be quoted as such:
“Trim on RAID 0 for SSDs is supported in the Intel RST driver versions 11.0 and newer. Currently available for the general public on Intel’s downloads site is RST driver version 11.2 which offers TRIM support on RAID 0 compatible with MS Windows 7 OS on Intel 7 series chipsets (earlier chipsets NOT supported). Intel is also working on a future release providing support for TRIM on RAID 0 on Microsoft Windows 8 OS for Intel 7 series chipsets. “

That is old news,

Intel released a driver a month ago which enables TRIM support for RAID O, just google INTEL RAID TRIM

you can build a system without any SSD and that disabledeletenotify will still be "0"

If it is set to zero it is enabled if it set to one then trim is off. Do a goolge search and you will see Microsoft, OCZ, & Anandtech all say. The Z77 chipset can have raid 0,1, 5 can run trim.

run (as admin)

fsutil behavior query DisableDeleteNotify

If the result is '0' TRIM is enabled. (Marked As Answer by Nicholas LiMicrosoft Contingent Staff, Moderator)


You need to verify that your "DisableDeleteNotify" is set to 0.

http://www.ocztechnologyforum.com/fo...ad.php?t=62405

By default it may be set to 1, which means trim is off.. just follow the directions in post 3
Where do you see that RAID 1 and RAID 5 on Z77 support TRIM pass through?

I'm starting to think it will never happen for Win7. They would have done it by now.

Z77 supports TRIM for SSDs in RAID 0 as of a while now, is that good for you? tongue.gif

How to enable TRIM Command in Windows 7 with a Solid State Drive

To enable or disable TRIM Command, you will need to open an Elevated Command Prompt window.

How To Open an Elevated Command Prompt window: Click on Start Orb > Type "CMD.exe" in Search box > Right click on "CMD" and select "Run as Administrator" (If you receive a prompt confirmation, click YES)

How to Enable TRIM Command

In the Elevated command Prompt windows, type the following:

fsutil behavior set disabledeletenotify 0

How to Disable TRIM Command

In the Elevated command Prompt windows, type the following:

fsutil behavior set disabledeletenotify 1

How do I know if TRIM is working in Windows 7?

In the Elevated command Prompt windows, type the following:

fsutil behavior query disabledeletenotify
Results explained below:
DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)


How to enable AHCI in Windows 7 after Instalation:

There is one way to fix this, although you need to have knowledge of registry editing. The detailed steps from Microsoft are as follows:

1.Exit all Windows-based programs.
2.Click Start, type regedit in the Start Search box, and then press ENTER.
3.If you receive the User Account Control dialog box, click Continue.
4.Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci
5.In the right pane, right-click Start in the Name column, and then click Modify.
6.In the Value data box, type 0, and then click OK.
7.On the File menu, click Exit to close Registry Editor.

After this you’ll have to restart your computer, go to BIOS and enable AHCI. When you log in to Windows again, you’ll notice the installation of drivers for AHCI. Another restart will be required to finish the driver installation.

These steps are provided at your own risk and not suggested unless you know and understand the risks. You will want to make sure the controller driver and MB BIOS support this option before you enable it

That windows disabledeletenotify thing only tells the user of Windows has the TRIM command active, not if the driver is actually passing it to the SSDs properly. You will get a 0 even if you don't have a Z77 chipset. And if you had a 1 and changed it to 0, it still does not mean that TRIM will be working. Also, say if the user has the SATA mode set to IDE and the disabledeletenotify shows up as 0, windows is enabling TRIM, however the IDE driver will not pass TRIM through to the SSD as the IDE driver does not support TRIM pass through. So what I and the others are saying is that the disabledeletenotify command does not accurately represent if TRIM is working or not.

In your setup TRIM works tho b/c you have Z77 chipset and supporting driver.

Solid-state drives have supported TRIM for years, but the command has never worked on drives participating in RAID arrays. However, Intel has now enabled TRIM support for RAID 0 arrays tied to its latest 7-series chipsets. You'll need to be running the RST 11.2 drivers (available from Intel's Download Center) in Windows 7 to pass TRIM commands to solid-state RAID arrays. Intel is also working on a Windows 8 driver with similar TRIM support, including the 7-series chipset limitation. Looks like last-gen platforms are out of luck.

AnandTech has put the new drivers to the test and confirmed that TRIM is indeed functioning as expected. Support is limited to RAID 0 arrays, though; RAID 10 configs aren't so lucky.

While we're happy to see Intel bringing TRIM support to RAID 0 arrays, it's unfortunate that support is limited to its latest platform. The 7- and 6-series chipsets share the same storage controller logic, so there should be no technical barriers to enabling TRIM on the older platform. This isn't the first time Intel has denied TRIM support to an older product, though. Intel released a TRIM-enabled firmware for its second-generation X25-M solid-state drive, but the first generation model, which uses the same flash controller, never got TRIM support.

The 10.6 RST drivers don't pass TRIM through to RAID-0 arrays, and the results show us just that: That's no surprise, but what happens if we do the same test using Intel's 11.2 RST drivers?

Here's what the pass looks like after the same fill, torture, TRIM, HD Tach routine with the 11.2 drivers installed:
Perfect. TRIM works as promised. Users running SSDs in RAID-0 on 7-series motherboards can enjoy the same performance maintaining features that single-drive users have.

Bringing TRIM support to RAID-0 arrays provides users with a way of enjoying next-gen SSD performance sooner rather than later, without giving up an important feature. Pretty much all high-end SSDs are capped to 6Gbps limits when it comes to sequential IO. Modern SATA controllers deliver 6Gbps per port, allowing you to break through the 6Gbps limit by aggregating drives in RAID.

I set up a Z77 testbed using Intel's DZ77GA-70K motherboard. I configured the board for RAID operation and installed Windows 7 SP1 to a single boot SSD. I then took two Samsung SSD 830s and created a 128GB RAID-0 array (64GB + 64GB). I picked the 830 because it benefits tremendously from TRIM, when full and tortured with random writes the 830's performance tanks. I secure erased both drives before creating the RAID array to ensure I started with a clean slate.

The 64GB Samsung SSD 830 is good for almost 500MB/s in sequential reads and under 160MB/s sequential writes. Two of them in RAID-0 should be able to deliver over 1GB/s of sequential read performance and over 300MB/s in sequential writes. A quick pass of HDTach confirms just that: Perfect. TRIM works as promised. Users running SSDs in RAID-0 on 7-series motherboards can enjoy the same performance maintaining features that single-drive users have.

Here's what the pass looks like after the same fill, torture, TRIM, HD Tach routine with the 11.2 drivers installed:
Perfect. TRIM works as promised. Users running SSDs in RAID-0 on 7-series motherboards can enjoy the same performance maintaining features that single-drive users have.
Bringing TRIM support to RAID-0 arrays provides users with a way of enjoying next-gen SSD performance sooner rather than later, without giving up an important feature. Pretty much all high-end SSDs are capped to 6Gbps limits when it comes to sequential IO. Modern SATA controllers deliver 6Gbps per port, allowing you to break through the 6Gbps limit by aggregating drives in RAID.
I set up a Z77 testbed using Intel's DZ77GA-70K motherboard. I configured the board for RAID operation and installed Windows 7 SP1 to a single boot SSD. I then took two Samsung SSD 830s and created a 128GB RAID-0 array (64GB + 64GB). I picked the 830 because it benefits tremendously from TRIM, when full and tortured with random writes the 830's performance tanks. I secure erased both drives before creating the RAID array to ensure I started with a clean slate.
The 64GB Samsung SSD 830 is good for almost 500MB/s in sequential reads and under 160MB/s sequential writes. Two of them in RAID-0 should be able to deliver over 1GB/s of sequential read performance and over 300MB/s in sequential writes. A quick pass of HDTach confirms just that: Perfect. TRIM works as promised. Users running SSDs in RAID-0 on 7-series motherboards can enjoy the same performance maintaining features that single-drive users have.

everybody knows that already, what is your point?
