RAID5
RAID5 is a storage performance, data security and storage costs into account storage solutions, it can be understood as RAID0 and RAID1 compromise. RAID 5 role is to provide security for the data system. And the data corresponding thereto parity information stored on the respective disks in RAID5. When a RAID5 disk data corruption, the use of the remaining data and parity information corresponding to recover corrupted data.
Advantages: data security, read and write speed, a high space utilization, storage costs are relatively low; support to ensure access to the data in the normal case of a disc off-line.
Disadvantages: the future, if a disk fails, the whole system performance will be greatly reduced.
Composition conditions: the same size of the disk at least three.
Raid5 need to create at least three disks, taking into account the actual production, we also need to configure a spare disk, so here we need to add a total of four disk and partition it with the file system type of modification.
You create the partition we can use them to build our raid5 rolled.
Once created you must remember to check the results of our creation.
raid5 volume has also been created, but then if you want to actually use raid5 also need to be formatted and mounted.
RAID6
RAID6 double parity technology, technical RAID5 adds a second independent parity block, the parity two separate systems using different algorithms so that the data reliability is very high.
Advantages: even if two disks fail at the same time will not affect the use of data to further strengthen the protection of data; data reliability.
Cons: Write performance is poor; disk utilization is low.
Composition conditions: the same size of the disk at least four. 
To create a raid6 raid5 is actually very similar to, but because it is the principle of the number of disks required will be more than raid5 piece created before raid6 we need to add them in and its partition with the file system type of modification.
The next step is that we create in the raid6.
After creating raid6 we also need to create a verification result.
After raid6 created us to be formatted and mounted it can really be used. 
RAID10
RAID10 is a combination of RAID1 and RAID0, do do first mirror strips, is compatible with the fault tolerance of RAID1 RAID0 strip of tape to read and write data advantages, good performance and high reliability.
Advantages: both safety and speed. 4 case basis, allowing RAID10 failure cabinet plate 2, as the number of hard tips, the amount will correspond to enhance fault tolerance.
Disadvantages: high cost, low disk usage.
Composition conditions: the same size of the disk at least four.
raid10 constituting need four disks, let's add four disks inside, and its partitions and modify the file system type.
According to the principle raid10, we next need to create four drives twenty-two two pairs raid1.
After creating raid1 we'll use raid1 create raid0. By this time our raid10 now created.
We also need to create a view of the results created.
raid10 started to use it needs to be formatted and mounted.
