Large servers for gaming or other purposes require the technology of, the Redundant Array of
Independent Disks, commonly known as RAID. A typical computer comes with one hard drive, but for the server to connect multiple drives, six defined RAID levels come for help. Combining more than one drive into one creates an array.
RAID 0 and RAID 1 are the two levels of RAID. The primary difference between these two levels is that RAID 0 uses Disk stipping and RAID 1 uses disk mirroring.
TechNinjaPro will compare these two categories for their features and usability in this article.
RAID 0 vs. RAID 1 Main Differences
A few significant points distinguish RAID 0 and RAID 1 from each other.
Stipping vs. Mirroring
RAID 0 uses stripping technology, in which it divides data into blocks and spreads them across multiple devices. For instance, it will spread the data using the hard disks and solid-state drives (SSDs).
On the other hand, RAID 1 uses the Disk mirroring feature. As a result, RIAD 1 will duplicate the data across multiple disks. Disk mirroring is an excellent solution for high-performance and high-availability applications, such as transactional applications, email, and operating systems.
The stripping feature of RAID 0 allows most of the storage of the drives in an array, and also it organizes the data in a way that is easy to understand.
But the replicate feature of RAID 1 uses half of the total storage plus, which makes the data very complicated.
RAID 0 does not have a write penalty, while RAID 1 does. If one of the drives fails, parity is a computed value utilized to restore data from the other drives. In case one of the processes fails, you cannot enter more data until both the data and the parity information have been entirely written to the disc. The RAID Penalty is the extra time spent waiting for the parity information to be written.
What Is RAID 0?
The main selling point of RAID is that it is created in a way that does reading and writing fast. The user does not have to worry about the slowing down issue because of the backup system.
In the stripping feature of RAID 0, data is divided uniformly across two or more discs. So, for example, in a two-disk RAID 0 configuration, the first, third, fifth (and so on) data blocks would be written to the first hard disc, while the second, fourth, sixth (and so on) data blocks would be written to the second hard disc.
In an attempt to give you a more precise image, let’s imagine that you have a 100 GB file and there are two disks in your array. What RAID will do is split it into ten 10 GB chunks. On Disk 1, you’d view the odd-numbered portions, and on Disk 2, you’d see the even-numbered portions. Because the pieces are in sequence order, the computer may load portions 1 and 2 simultaneously, then 3 and 4, and so on, thereby slashing total load times.
Advantages of the RAID 0
TechNinjaPro has gathered the list of advantages of the RAID 0. Further in the article, you will find the benefits of using RAID 0 for the server.
Fast writing and reading speed
As discussed earlier, the RAID 0 provides you with fast writing and reading speed without even worrying about the data backup.
There is no method to check for parity, which allows you to use the entire storage capacity of each disc.
RAID 0 is supported by RAID controllers of all sorts
A RAID controller is a storage component that controls all the disk drives connected as an array. It provides the physical disc drives to the computer or server that manages the RAID infrastructure as logical units. A disc array controller is another name for a RAID controller.
Easy to Setup
Raid 0 is quite simple to set up. The first step is to determine whether or not your motherboard includes a built-in Raid controller (most of the latest motherboards do).
RAID 0 is a cost-effective and technically straightforward technique for data protection that also increases performance.
Disadvantages of RAID 0
Listed down below, you will find the disadvantages of using RAID 0 for the server.
No fault-tolerance comes with RAID 0. As a result, if your data is lost or corrupted, you won’t be able to recover it, making RAID 0 inappropriate for storing sensitive data.
No data backup
Because RAID 0 does not create a duplicate of the data, you will lose all of your data if one drive fails in your RAID 0 server.
What Is RAID 1?
RAID 1 is known for creating backups of all the important at the expense of performance and storage space. In the pursuit of creating backups, a computer will “mirror” the data from one disc onto another, making a perfect clone and backup.
Let’s take the same example if you have a file of 100 GB, the computer will duplicate data rather than break it as it does in a RAID 0 server. This process will take place when you enter the data, and it will make any modifications on one disk on the other simultaneously.
Advantages of RAID 1
Here is the list of advantages of the RAID 1 that TechNinjaPro has gathered for you:
RAID 1 comes with the feature of mirroring that allows you not to worry about data loss, as it will create the same copy of the file on two different drives. So if one drive corrupts, you will still be able to access them from the other drive.
RAID 1 has the feature of fault tolerance, unlike RAID 0. With this attribute, If one of the drives fails, the RAID 1 system will reboot, and the second disc will take over. This means that a disc failure will not affect the end-user.
Easy Data Access
When using RAID 1, data is accessible whenever it is needed. Because the data is replicated across different disks, data loss is inconsiderable. In addition, data can be read from more than two drives simultaneously; this also means that performance is also great.
Disadvantages of RAID 1
Following is the list of Disadvantages of the RAID 1 that TechNinjaPro has gathered for you:
Utilize half of the storage
As discussed earlier, it gets to use only half of the storage; the other half is used for duplicate files. This could be one of its disadvantages because some people require more storage.
More expensive than RAID 0
Since RAID 1 requires more drives to store the same amount of data like RAID 0, it will become expensive.
After doing proper research on both RAID levels, TechNinjaPro has concluded that both RAID levels can be used depending on the user’s preferences.
When Raid 0 Can Be Used?
RAID 0 is recommended for those who are looking for cheap server technology with excellent performance. However, RAID 0 is not reliable because of lacking a data backup facility.
Besides all of this, you can still ensure data protection and redundancy by using disk stripping on your system.
When Raid 1 Can Be Used?
RAID 1 is recommended for those who are looking for a dependable server that ensures zero data loss. People use this array for accounting-related data.
It is suited for little servers with only two disks and if you’re looking for an easy setup.
