Can anyone tell me the difference between RAID 5 and RAID6?
When it is about RAID 6, it runs on two separate parity schemes that are allocated across different hard drives. It needs minimum of four hard drives as compare to RAID 5 that is at least three hard drives. Since RAID 6 uses two independent parity schemes that must be computed moreover, it possesses the controller head which is greater than the RAID 5.
Since RAID 6 is made up of various hard drives so, there is a possibility that it can suffer failure of more than one hard drive whereas, RAID can get failed as a result of one hard drive damage.
RAID 6 is structured or configured through hardware whereas; RAID 5 can be done either ways hardware as well as software.
However, no matter the type of RAID you opt for whether RAID 5 or RAID 6, you should never rely on these RAID rather maintain a regular backup of your data. Otherwise, in case of data loss RAID recovery could become challenging.
