Usable capacity is always two less than the number of available drives in the RAID set. Usage: Similar to RAID 5, including file servers, general storage servers, backup servers, etc. Poor random write performance makes RAID 6 unsuitable for database applications. 2021-04-09 RAID is an acronym for Redundant array of inexpensive disks and as this full form suggest it is a collection of disk arranged or set up so that it provides redundancy and availability. There are many types of RAID which are known and used in industry to provide redundancy and today we are going to talk about RAID 6, which provides 2 disk fault tolerance.
Setup RAID 6 in Linux. To setup a RAID 6, minimum 4 numbers of disks or more in a set are required.RAID 6 have multiple disks even in some set it may be have some bunch of disks, while reading, it will read from all the drives, so reading would be faster whereas writing would be poor because it has to stripe over multiple disks.
In a dynamic pool, drives are partitioned into drive extents. These extents 9 Apr 2021 Technical Specifications for RAID 5 and RAID 6. RAID 5 arrays require a minimum of three disks. RAID 6 arrays require a minimum of four disks.
RAID-6 storage systems protect k disks of data with two parity disks so that the system of k + 2 disks may tolerate the failure of any two disks. Coding techniques
The most common types are RAID 0, RAID 1 and its variants, RAID 5, and RAID 6. Multiple RAID levels can also be combined or nested, for instance RAID 10 or RAID 01. RAID levels and their associated data formats are standardized by the The minimum disks that are needed for RAID 0, RAID 1, RAID 5, and RAID 10: In order to create RAID 0, you only need at least two disks. Since this type of array does not have fault tolerance, it should be used in areas where the data is constantly updated and does not have strategic importance, but at the same time requires high performance. Raid 6 is an extension of RAID 5 and uses two parity block for working which is distributed among all the disks in the RAID pool of RAID 6 and thus requires minimum 4 disks for its operation. With 2 parity blocks, it has the capability to compute data at a time of 2 disk failure.
If you're looking for a RAID card though, I wouldn't recommend Adaptec a whole lot. RAID 6 and RAID 5 do not do this, leaving open the chance of data corruption that RAID 10 can help avoid since the controller should flag the drive as bad if there are any read errors. Wife's build: Amethyst - Ryzen 9 3900X, 32GB G.Skill Ripjaws V DDR4-3200, ASUS Prime X570-P, EVGA GTX 1080 SC, Corsair Obsidian 750D, Corsair RM1000
The minimum number of drives required for RAID 6 is four. Technically there's no reason why you couldn't set up a RAID 6 array with only three disks, but most RAID controllers don't support this. (See Why does RAID 6 require at least 4 disks? Two independent parity computations must be used in order to provide protection against double disk failure. Two different algorithms are employed to achieve this purpose.

RAID 6 implementations require a minimum of four drives and have the storage capacity of N-2 drives because the equivalent capacity of two drives is exclusively dedicated to holding parity data. Also, you only need a minimum of three disks to implement RAID 5 as opposed to four drives of RAID 6. Disk failure.
