What is a RAID 6?

RAID 6, also known as double-parity RAID (redundant array of independent disks), is one of several RAID schemes that work by placing data on multiple disks and allowing input/output (I/O) operations to overlap in a balanced way, improving performance.

What is a RAID 6 configuration?

RAID 6 is a type of RAID level that utilizes block-level striping and distributes two parity blocks on each disk within the array. It is considered an enhancement to RAID level 5, but adds an additional parity block on each disk in the array. RAID 6 is also known as double-parity RAID.

What is RAID with example?

1. Short for redundant array of independent disks, RAID is an assortment of hard drives connected and set up in ways to help protect or speed up the performance of a computer’s disk storage. The picture of the Drobo is a good example of a device using RAID technology.

Why is RAID 6 bad?

RAID 6 RAID 6 tackles this problem by creating enough parity data to handle 2 failures. You can lose a disk and have a URE and still reconstruct your data. Some complain about the increased overhead of 2 parity disks. But doubling the size of RAID 5 stripe gives you dual disk protection with the same capacity.
