      • RAID 6 is similar to RAID 5 but uses double parity information, allowing it to withstand the failure of two disks simultaneously. RAID 6 requires an array of 4 or more disks to operate. Advantages: higher reliability compared to RAID 5. Disadvantages: high disk costs, as half of the capacity is used for duplication.

    Aug 19, 2021 · Compared to RAID 5, the extended RAID 6 has one decisive advantage: parity information to recover lost data is saved in duplicate. Duplicated parity data is a more efficient way of creating redundancy, and also ensures higher reliability .

    In a RAID 0 system data are split up into blocks that get written across all the drives in the array. By using multiple disks (at least 2) at the same time, this offers superior I/O performance. This performance can be enhanced further by using multiple controllers, ideally one controller per disk.

    Data are stored twice by writing them to both the data drive (or set of data drives) and a mirror drive (or set of drives). If a drive fails, the controller uses either the data drive or the mirror drive for data recovery and continuous operation. You need at least 2 drives for a RAID 1 array.

    RAID 5 is the most common secure RAID level. It requires at least 3 drives but can work with up to 16. Data blocks are striped across the drives and on one drive a parity checksum of all the block data is written. The parity data are not written to a fixed drive, they are spread across all drives, as the drawing below shows. Using the parity data, ...

    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. The chances that two drives break down at exactly the same moment are of course very small. However, if a drive in a RAID 5 systems dies and is replaced by a new drive, it takes hours or eve...

    It is possible to combine the advantages (and disadvantages) of RAID 0 and RAID 1 in one single system. This is a nested or hybrid RAID configuration. It provides security by mirroring all data on secondary drives while using striping across each set of drives to speed up data transfers.

    These levels do exist but are not that common (RAID 3 is essentially like RAID 5 but with the parity data always written to the same drive). This is just a simple introduction to RAID-systems. You can find more in-depth information on the pages of Wikipedia or ACNC.

    All RAID levels except RAID 0 offer protection from a single drive failure. A RAID 6 system even survives 2 disks dying simultaneously. For complete security, you do still need to back-up the data stored on a RAID system. 1. That back-up will come in handy if all drives fail simultaneously because of a power spike. 2. It is a safeguard when the sto...
