RAID Calculation 101: The Basics of Calculation of RAID

For those of you who do not understand the computer lingo or jargon and are trying to understand how to calculate and operate RAID then it is important for you to know the very basics of it first. So the first thing that you need to know about RAID is that it stands for Redundant Array of Independent Disks and it is a technology that essentially virtualizes data storage and its primary function is to combine a lot of physical disk drive and its components into one place so that the redundancy in the data is minimized and it can help in improving the performance overall. If you trace the historical origin of the term, it was originated or coined in a famous paper in which the authors argued that an assortment of magnetic disks, which are much cheaper than a mainframe computer drive, are better in terms of data storage. In the system of RAID, the distribution of data is done on different devices and these are known as RAID levels. So in order to make the most of it, people try to calculate RAID capacity and speed and if you want to know how it’s done then you are in the right place because we will be talking about it down below, check it out.

Calculation Process of RAID

For the purpose of calculation of the capacity of a disk selection, you have to keep in mind the specs of each disk or magnetic disk, or some parts of it will be allocated for usability of the disk like mirroring or parity. After that, you will have to know the remaining number as well as the size of the disk so that they can be compacted together in one disk. It is actually that simple, but since the process itself sounds complicated a lot of people do not go ahead with the calculation.
