Configuring RAID correctly is important to ensure that the computer can identify the hard drives in the RAID pool and boot into the operating system.
RAID-related issues can occur if the computer does not support RAID feature, incorrect RAID configuration, and hard drive failure.
Here are some steps that enable you to identify if a Redundant Array of Independent Disks (RAID) solution is possible on your computer. Here are some steps taking you through how to accomplish setting RAID up, if your computer supports it.
Follow the guides below.
Most desktops and some laptops can support a RAID configuration.
For optimal experience, you must have two hard drives of equal size and capacity that are installed in your computer.
This type of RAID does not involve a hardware RAID card. Instead it uses the BIOS along with the Intel Chipset and matrix storage software on older computers. Intel Rapid Storage Technology is used on our newer models. It creates a type of Software-controlled RAID. This type of RAID configuration only supports RAID 0 and RAID 1.
Is your computer capable of having more than 1 Hard Drive installed?
No, then I am afraid RAID is not going to be possible on your computer?
Yes, then go to the next step.
In your BIOS is RAID an option against the SATA Operation Mode?
You can get to the BIOS on a Dell computer by tapping the F2 key at the Dell splash screen.
No, then I am afraid RAID is not going to be possible on your computer without purchasing additional hardware.
Yes, then go to the next step.
Go to the Dell Support Site and enter you Service Tag. Go to the Drivers and Downloads for your computer. (On older computers you can see the Intel Matrix Storage software under the Chipset category. On newer computers, it is under the Serial ATA or Storage category that you can see the Intel Rapid Storage Technology software listed.)
No, then I am afraid RAID is not going to be possible on your computer without purchasing additional hardware.
Yes, then go to the next step to be taken through the configuration process.
You must have two Hard Drives of equal size and capacity. You must have decided if you want to use RAID 0 or RAID 1. We recommend RAID 1.
Mirrored Disk Array - Provides redundancy in case one of the two drives fails. This allows for all data to be duplicated, but is not as fast as a RAID 0. If a disk fails, the data can be recovered from the second disk. The drawback is you half the size of your total capacity, and it is slower to write and it does it to both drives. The benefit is if one disk fails you still have all your data and can rebuild from the surviving disk.
RAID 0 (Striping) | RAID 1 (Data Mirror) | |
---|---|---|
Description: | Offers performance benefits over a single hard drive configuration. This is ideal for users who work with large files or require fast data access. | Offers backup integrity by having the same data on two drives. If one drive fails, the data is still intact on the other hard drive. This is ideal for applications where data integrity is of utmost importance. The identical data is housed on both drives. That means that the storage capacity for the entire array is equivalent to the size of the smallest drive in the array. |
System: | ||
Computer Sees: |
2 x 320 GB = 640 GB | 320 GB |
Characteristics: | RAID controller breaks the data into blocks and distributes the pieces to both drives simultaneously. | RAID controller writes the same data to both drives. |
Customer Benefit: |
RAID 0 offers performance benefits over a single hard drive configuration. This bundle is ideal for early adopters and power users that manipulate large files or require fast data access. | RAID 1 offers data integrity by having the same data on two drives. If one drive fails, the data is still intact on the other hard drive. This bundle is ideal for applications where the data integrity is of utmost importance. This should not be considered a data backup however. |

Enter System Setup or BIOS by tapping the F2 key at the Dell splash screen.
Go to the category that contains the SATA Operation mode.
Select the SATA Operation Mode.
Change the mode to RAID On if it was not already set and apply or click yes.
If the setting was changed from RAID Autodetect/ACHI or RAID Autodetect/ATA to RAID On. If it was not, then leave it as set.
Press Esc to bring up the exit from BIOS screen.
Select Save and Exit, to exit System Setup and resume the boot process.
When the SATA Operation field in System Setup has been set to RAID On, the computer displays a RAID BIOS message. The message is seen after the Dell splash screen shows during POST - but before Windows starts. The message below is what is displayed if no RAID volume is created.

On Start Up you must press the Ctrl + I keys to enter the Intel RAID Option ROM utility.
Creating a RAID 0 or a RAID 1 Configuration
Select Create RAID Volume and press ENTER.
Enter a RAID volume name or accept the default and press ENTER.
For RAID 0, select RAID 0 (Stripe) and press ENTER or for RAID 1 select RAID 1 (Mirror) and press ENTER.
Select the two drives that constitute the RAID configuration and press ENTER.
For RAID 0, change the stripe size and press ENTER.
For RAID 1, skip this step.
Select the wanted capacity for the volume and press ENTER.
Normally you would go with the default size as the maximum available size.
Press ENTER to create the volume.
Press the Y key to confirm creating the RAID volume.
Check that the correct volume configuration is displayed on the main Intel RAID Option ROM utility screen.
Select Exit and press ENTER.
Install the operating system.
Power on your computer and repeatedly press F12 at the Dell Logo to open the boot menu
Select device configuration using the arrow keys (See figure 1).

You can select a disk for your RAID volume by highlighting it and pressing spacebar or enter and selecting X (See figure 5)
Figure 5: Select RAID member disks
Choose the volume and stripe size and select Create Volume to finish. The RAID Volume is now shown in the Main screen. (See figure 6)
Figure 6: RAID-Volume created
You can now install the operating system
The computer has already got one hard drive with the operating system installed on it and you want to fit a second drive. You want to configure them both as RAID without losing the existing data. You can use the migrating option in the Intel Matrix Storage Manager in your Operating System.
Click the Start button and go to All Programs\Intel Matrix Storage Manager\Intel Matrix Storage Console to launch the Intel Storage Console.
On the Actions menu, you want to select Create RAID Volume From Existing Hard Drive to launch the Migration Wizard.
Click Next on the Migration Wizard screen.
Enter a RAID volume name or accept the default.
Choose from the following options:
For RAID 0, select RAID 0 as the RAID level from the drop-down box, select the appropriate stripe size from the drop-down box and click Next.
For RAID 1, select RAID 1 as the RAID level from the drop-down box, go on to the next step.
On the Select Source Hard Drive screen, double-click the hard drive from which to migrate your data and click Next.
On the Select Member Hard Drive screen, double-click the hard drive to select the member drive on which to span the array and click Next.
For RAID 0, on the Specify Volume Size screen, select the wanted volume size, and click Next.
For RAID 1, go on to the next step.
Click Finish to start migrating or click Back to make changes.
The computer can be used normally during the migration process.
