Does not RAID stand for Redundant Array of Independent Disks instead of inexpensive I ask this becasuse 3TB drives can be used in a RAID array and they are NOT inexpensive.It makes Native Command Queuing (NCQ) along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible.
NCQ allows the OScontroller to request up to 32 simultaneous requests at once. So you basically get more performance from your drive over older IDE mode. It is a means by which your PC uses multiple disks as if they were one, either to increase performance, safeguard against disk failures, or both. There are four main factors of a RAID setup: striping, which spreads data across multiple drives, mirroring, which copies the data to more than one disk, space efficiency, which is how much of the total space is available to use, and fault tolerance, which is a measure of how well protected the RAID array is against disk failure. Sata Operation Bios Setting Drivers For TheThe reason why is Windows disables the drivers for the others that are not needed during installation. Sata Operation Bios Setting How To Enable TheThis tutorial will show you how to enable the different SATA modes after you have installed the OS. Notes: You may need to install the IRST driver first in order to do the registry change from AHCI mode to RAID mode for Intel mobos. You may have to uninstall then reinstall any SATA drivers such as Intel RST or AMDs equivalent. Sata Operation Bios Setting Windows 7 Raid DriverNote: You might not have the last registry key (iastor) as this is installed in the registry with the intel raid drivers, the default windows 7 raid driver uses the iastorV key. Note: If you have an AMD systems you may need to look here too. The JMicron SATA ports do support AHCI, but youd get worse performance running a HDD through these, than on the normal SATA ports. You can uninstall the Nvidia controller though in Device Manager and install Microsofts IDE Controller, which can send TRIM commands for SSDs. Right click one of them and click Properties and go to the tab. Click Update. Click Browse my Computer, and then Let me pick. You will see the option to choose Standard Dual Channel PCI IDE Controller. Do the same for the other two Nvidia Controllers in Device Manager and restart your system. After the controllers have installed, you will be asked to reboot again. SSDs will now have a slight performance boost with the TRIM command, and also regular HDDs also have a slight increase as well. Right-click on the entry name, select Modify, change the value from 3 to 0 and click OK. Edit: I was able to figure out how to set up RAID by using Win 7 Dism Manager. Now to power off add 4th drive that I need to copy files from and cross my fingers all goes according to plan.
