Operating a RAID system requires at least two or more storage drives. These work together and form a group of drives. This is also more efficient than one single drive. | Operating a RAID system requires at least two or more storage drives. These work together and form a group of drives.

- | ==== How to set up a RAID configuration on XH270? ==== | + | |
- | + | ||
- | __The following requirements must be met before setup.__ \\ | + | |
- | The XH270 must be ready for operation with at least two hard disks installed and connected to the SATA ports.\\ | + | |
- | Boot Mode in BIOS must be set to UEFI. | + | |
- | ---- | + | |
- | + | ||
- | 1.) \\ | + | |
- | \\ | + | |
- | Power on the XH270 and while booting please press the “Del” key to enter BIOS. | + | |
- | Navigate to the “Advanced” tab, and enter "SATA Configuration" | + | |
- | + | ||
- | {{ : | + | |
- | + | ||
- | ---- | + | |
- | 2.) \\ | + | |
- | \\ | + | |
- | - Under "SATA Mode Selection" | + | |
- | - Now save your settings by pressing the F4 key on the keyboard and restart the XH270. | + | |
