RAID or Redundant array of independent disks provides you the function to store data combining multiple physical disk drive components into one or more logical units for data redundancy.
It contributes highly to enhancing performance and gives a highly reliable storage option in the form of disk drives or software.
How the RAID is functioned?
It functions by distributing data across hard drives depending on the required level of redundancy and performance. Your slots of Hard drives are distributed with a copy of your original data so if your original data misses out, there’s still a backup. There also comes RAID chips or hardware RAID chips which can be used to store data as a backup.
Uses of Raid
RAID can be super-efficient to use as it offers safety and recovery for your valuable data and ensures that you never miss out. It though comes in two forms, hardware RAID and software RAID.
Hardware RAID is the same as we discussed above where there is a hard drive storing the copy of original data.
Software RAID performs its functions and processing on the host’s CPU. It does not comprise the server processor loading data which has some effects on its performance.
The real question arises which is better?
Well, software RAID is considered to be efficient as with any system you can use it but there are some performance measures in which software RAID may lag.
Here Hardware RAID plays a major role in providing the topmost performance as with Hardware RAID, logical disks are replicated outside the system where a physical controller manages the system. This controller presents data to applications and operating systems as logical units.
Software RAID is also considered by businesses as it poses a convenient option but not a sure option to give utmost availability.
On the other hand, Hardware RAID gives a powerful alternative to store and recover data without any breaches.
