To replace a failing RAID 6 drive in The RAID-6 technology divides data into blocks and place them in "horizontal sections", enclosing one block of every of n disks. In each section, there are Sep 3, 2015 RAID 6 gives a large percentage of capacity with better protection, but at the cost of more performance. It is sadly becoming more and more RAID 6 is essentially an extension of RAID 5 that allows for additional fault tolerance by using a second independent distributed parity scheme (dual parity). Even if 5 days ago RAID 6 is one of the most popular levels of RAID because it can withstand two drive failures and still protect the data stored in the array.

RAID 6 is a lot more CPU intensive than RAID 5 which is generally unnoticeable load on modern systems except under extreme disk activity. RAID 6 will tolerate loss of ANY 2 drives, where RAID 10 could tolerate up to a loss of 5, but Murphy’s Law says you’ll lose the 2 in the same mirror, so RAID 10 cannot tolerate the loss of ANY 2 drives.

RAID 6 is a type of RAID level that utilizes block-level striping and distributes two parity blocks on each disk within the array.

In both the RAID 5 and 6 cases, I would add a hot spare to add resilience. If you were to spend a bit more on a setup, go for RAID 10 - it has both good read and write performance and up 50% failure tolerance.

Efekt tych prac spowodował jednak, że obecnie niewielu producentów stosuje RAID 6 w swojej "czystej" formie, a proponuje własne systemy, różniące się głównie nazwą i czasem szczegółami konstrukcyjnymi.
