For RAID 0 select RAID 0 (Stripe) and press or for RAID 1 select RAID 1 (Mirror) and press.Enter a RAID volume name or accept the default and press.This opens the Intel RAID Option ROM utility in the BIOS for creating a RAID 0 or a RAID 1 Configuration.On Start-up user must press the F12 key then arrow keys to select Device Configuration on the Boot Options menu.However if there is no RAID configured then the screen will display a No RAID volume message.When the SATA Operation field in System Setup has been set to RAID On the system will then display a RAID BIOS message after the Dell splash screen shows during POST.Select Save and Exit, to exit System Setup and resume the boot process.Press to bring up the exit from BIOS screen.Change the mode to RAID On and apply or click yes.Navigate to the category that contains the SATA Operation mode.Enter System Setup or BIOS by tapping the key at the Dell splash screen.

Steps to install the Operating system with RAID

The drawback is that there is half the size of your total capacity and it's slower to write and it does it to both drives.ģ.

If a disk fails, the data can be recovered from the second disk.This allows for all data to be duplicated on the fly but is not as fast as a RAID 0.Provides redundancy in case one of the two drives fails.

The only benefit to this method is it speeds up write times to the drive which makes the system quicker and it keeps the full size of the disks.The drawback to this method is if one drive fails, then all data in the array (both disks) is lost.I'm not aware of support in Grub to declare two disks as.

Make sure that your Grub configuration doesn't hard-code disks like (hd0), but instead searches for the boot and root filesystems' UUIDs. Then both drives will be able to boot alone.

This improves performance but puts all data at risk in the event of a disk failure. If the two disks are /dev/sda and /dev/sdb, run both grub-install /dev/sda and grub-install /dev/sdb.

Provides data striping (spreading out blocks of each file across multiple disks) but no redundancy.

NOTE: Requires 2 HDD's of equal size, capacity and type.
