What you need to know about RAID Level in Data Management System?

In the world of technology, everyone has ever heard the name of the RAID. But many people do not know what this actually is and what it does. Today’s our small effort to tell the people who do not know them.

RAID means the Redundant Array of Inexpensive Disks. The name suggests that it is a matter of storage or storage. Yes, okay. And today we will talk about all the relatives of RAID and RAID, which is RAID 0, 1, 10, 5 and 6.

So let’s first focus on it:

Raid is usually used by professionals more than home computer users. Although no RAID setup is attached to the Motherboard before, it is essentially available on almost all the current board, since home users are also stuck on this RAID. The main reason for using RAID is to consolidate multiple drives and to gain more performance and information. The current motherboards can control RAID 0, 1 and 10 without any card. However, I think it is better to use professional RAID cards if necessary. There is less risk of system failure or loss of data. . So let’s talk about them.




When we talk about RAID 0, we have to first say that it is designed for speed and performance. However, data transfer speed will increase at that rate at the rate of loss of information will increase! Yes, the relativity of the RAID 0 is very low-grade.
For RAID 0, the space and speed are twisted by combining two drives. For example, two SSDs of 500 GB will be assembled together by a single drive, due to which the total capacity will be 1000 GB and the speed of two drives will be doubled and the speed will be doubled. That means if the SATA is combined with two SSD 3.60 GB / sec, the speed will be about 12 GB / second. But in this case if any SSD is lost then we will lose all the information. Who can be called speed over the cost of reliability.




Although RAID 0 looks like this, its work is completely opposite to it. That means there will be 500 GB even after assembling two 500 GB in here. So the question is, where did I drive another drive? The drive is also there, but mirrored. For anyone who wants to keep track of the drive’s speed and capacity of a drive instead of the speed and capacity of two drives, this is for those RAID 1. The information that is read and write on a drive here is exactly the same information mirrored in other drives. Because of that, due to some reason a drive is lost, all the other drives are found without any problems. I personally use RAID 1 on my computer to save sensitive information.


RAID 10:


Speaking of RAID 10, mix raid 0 and RAID 1 together, which can be found. Although this is not a perfect solution, it can be said that “the best solution available without using a RAID card.” The minimum requirement of 4 drives for RAID 10 is required. If you want to add more; But I’m going to give a four example example here.

In this case, you can save information to 4 drives. However, there will be two RAID 1 features; Two of the features of RAID 0 This means that both the speed and loyalty are available in this setup. In this set, if two drives are lost for any reason, we can recover the complete information.

Let’s go this time on the professional side, that is, RAID5 & RAID6.



For a RAID 5,6 setup, a professional RAID solution card is required.



Like RAID 1, RAID 5 is basically designed to save information. In this case, there is a minimum of three drives where a drive is kept reserved so that any type of drive failover can recover data on this drive that was lost in drive. That means if you have 6 drives, you will get a capacitance of 5 drives. As it spreads data to all drives in the form of straps, you can see data quickly. But without a good quality Raid card, it is very time-consuming, and if it fails on a drive, then it will be a long way to recover data in that drive.




RAID 6 is a more reliable version of RAID 5. It can protect itself from Drive Failure and recover all lost data again, with saved data cycles in the Drive reserve. This requires a minimum of 4 drives. However, with no 4 drives, no one uses RAID 6 because the RAID 10 is the best solution. However, when the drive is more then this RAID 6 is quite useful. As 8 drives, the capacity of the RAID 6 will be available to drive 6, where it could be found on RAID 4. RAID 6 is seen to be used in large mainframes on computers, where there is no chance of losing anything. For example, online storage is stored or called in English, online storage hosting. I have seen only one of the weaknesses of RAID 6 which means that RAID 6 is less than Wright 5.

Regardless of the benefits of the RAID, I personally do not see a similar role. But that does not mean that it’s not a good thing for ordinary computer users. RAID is a great solution for those who have been collecting media files or movies or games or series or personal photos and videos for a long time. At the same time, I think there is no way to get more speed and loyalty RAID at low cost.


Today you know that you have a general idea of RAID. If someone wants to know more information or wants to set up RAID itself, and want a step by step guide on this, then let me know in the comments section.
