New Intel Chipset Drivers Bring TRIM Support for RAID Setups
The TRIM feature introduced by the newest generation of operating systems makes solid state drives more efficient with write performance. However, it does not work when RAID arrays are built with SSDs, until now. The latest version (9.6.0.1014) of Intel Rapid Storage Technology driver enables TRIM for each of the SSDs that are part of a RAID volume, of all RAID types, with the exception for RAID 5. The software can be downloaded from here.
Introduced with Microsoft's Windows 7, Windows Server 2008 R2, and with Linux 2.6.33, TRIM is a feature which uses system idle time to physically erase deleted data, since unlike with magnetic hard drives, data can't be simply overwritten on areas with deleted data. Deleted data must be erased before a NAND flash device can store fresh data in its place, and this causes additional write-cycles on setups without TRIM support. TRIM erases deleted data whenever feasible so that lesser number of write cycles are spent when there's data to be actually written in its place, increasing performance.

Quoted from Intel download page: "Intel® Rapid Storage Technology Driver for Intel Desktop Boards" and "Installs the Intel® Rapid Storage Technology (RAID) driver version 9.6.0.1014 for Intel® Desktop Boards."
You may need/wish to do the F6 install, if you wish to boot to a new install of Windows 7 with raid enabled in your bios using the Intel chipset. This will install the drivers, not the control interfeace, that is why they state this "Download the driver (STOR_allOS_9.6.0.1014_PV.exe) and one of the following F6 Driver Diskettes (depending on your operating system)".
STOR_allOS_9.6.0.1014_PV.exe contains the control interface and driver, but if you already have the driver installed, all it will do is look to see if you have the latest driver. And, since you probably do, it will just install the control interface.
Anyone, please correct me if I am wrong:)
After :confused: Burst rate
Are you a pimp? :pimp:
3tb doesnt work for the post from DirectorC
but 2tb didnt want to work for me for some reason
EDIT: hmm maybe not in raid though will have too look into it
EDIT EDIT: You can do it on raid too, with the right hardware and software (xp x64 or newer) including intel ICH 8/9/10R
This is simply NOT true. I know you guys are excited about this, but if you read the tech notes and FAQ on the intel website, they give you specifics.
The trim will work for drives setup through a raid controler that are NOT part of the raid members. Meaning that you can have two hard drives set up and a third non raid member drive. The non member drive will be detected and able to comunicate through the controller.
Those disk in RAID will not be trimmed.
Sorry to burst you guys bubble.
