If one of the disks fails, data can be recovered from the remaining disks.

|
|
Data being sent to the server is checked for errors, which are automatically corrected if discovered.
|
|
|
If a network connection to the server goes down, traffic is automatically routed to a different server.

|
|
Boot times are improved since the operating system is distributed among multiple disks.

Detailed explanation-1: -RAID works by placing data on multiple disks and allowing input/output (I/O) operations to overlap in a balanced way, improving performance. Because using multiple disks increases the mean time between failures, storing data redundantly also increases fault tolerance.
Detailed explanation-2: -By placing data on multiple hard drives, input and output operations overlap in a balanced manner. Because multiple hard drives increase the mean time between failures (MTBF), storing redundant data also increases fault tolerance.
Detailed explanation-3: -RAID fault tolerance gives the array some slack in the case of hard drive failure (which is inevitable and will happen to you sooner or later) by making sure all of the data you put on it has been duplicated so that it can be restored if one or more hard drives fail.
Detailed explanation-4: -RAID 5 is a redundant array of independent disks configuration that uses disk striping with parity. Because data and parity are striped evenly across all of the disks, no single disk is a bottleneck. Striping also allows users to reconstruct data in case of a disk failure.
Detailed explanation-5: -RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data.
