## Raid 1
|

|
||||
Raid 1 creates a mirror with even amount of drives.
|
||||
|
||||
### Create Raid 0 device
|
||||
|
||||
You can create a Raid 0 device with
|
||||
`mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sda /dev/sdb`
|
||||
where `sda` and `sdb` are the disks you want to include in your raid.
|
||||
You can increase the number of raid devices, but they have to be at least 2.
|
||||
If it is an uneven amount of disks in the raid, a disk will act as a spare disk.
