![]() The size of a RAID 1 array block device is the size of the smallest component partition. Please note that with a software implementation, the RAID 1 level is the only option for the boot partition, because bootloaders reading the boot partition do not understand RAID, but a RAID 1 component partition can be read as a normal partition. The example will be using RAID 1 for everything except swap and temporary data. If one of those drives fails, the block device provided by the RAID array will continue to function as normal. ![]() As with other RAID levels, it only makes sense if the partitions are on different physical disk drives. RAID 1 The most straightforward RAID level: straight mirroring. ![]() The size of a RAID 0 array block device is the size of the smallest component partition times the number of component partitions. On a server, RAID 1 and RAID 5 arrays are more appropriate. If the speed increase is worth the possibility of data loss (for swap partition for example), choose this RAID level. It does, however, provide a big speed benefit. Even though it does not provide redundancy, it is still considered RAID. There are many different levels of RAID listed below are the most common. Furthermore, installing a system with RAID is a complex process that may destroy data. A RAID will not protect data if there is a fire, the computer is stolen or multiple hard drives fail at once. RAID levelsÄespite redundancy implied by most RAID levels, RAID does not guarantee that data is safe. Warning: Be sure to back up all data before proceeding.
