RAID 6. RAID 6 is like RAID 5, but the parity data are written to two drives. That means it requires at least 4 drives and can withstand 2 drives dying simultaneously. Read speed is as fast as RAID 5, but write speed is slower than RAID 5 due to the additional parity data that have to be calculated.

RAID 6 — RAID 6 liknar RAID 5, men har dubblerade checksummor. Om man sätter ihop n diskar med RAID 6 så kommer man att kunna A RAID 6 array with a single failed disk has similar protection to that of a RAID 5 array with no disk failures.

RAID 6 arrays must be built from at least four disk drives. Maximum stripe size depends on the number of disk drives in the array.

RAID 6 uses both striping and parity techniques but unlike RAID 5 utilizes two independent parity functions which are then written to two member disks. Typically, one of these parity functions is the same as in RAID 5 (XOR function), while the second is more complex. RAID 6 is faster on reads, slower on writes.

Drawback of Raid 6 is that you will have a way longer rebuild time if you have a faulty drive.

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. This RAID calculator computes array characteristics given the disk capacity, the number of disks, and the array type. Supported RAID levels are RAID 0, RAID 1, RAID1E, RAID 10 (1+0), RAID 5/50/5E/5EE, RAID 6… 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. 2007-06-08 2020-11-26 RAID 6 is an upgrade from RAID 5: data is striped at a block level across several drives with double parity distributed among the drives. As you have with 5, parity information allows … RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme (dual parity) Data is striped on a block level across a set of drives, just like in RAID 5, RAID 6 (ADG), like RAID 5, generates and stores parity information to protect against data loss caused by drive failure.
