The Best RAID For NAS

We are living in a technological world, and in the past few years, many advancements are made in the field of information technology. The world is evolving at such a rapid speed that everybody wants more advanced techniques to use, and when we talk about the data storage devices and laptops, they have their importance. There are many tools available in the market to keep your data safe and secure. Data stores in the hard drive of a computer and laptop, and you must have to take data backup to prevent any loss. In this modern world, RAID and NAS are two of the most used and reliable data storage devices. Both of these devices used to store data at multiple places to make it secure. One of the other important things here is that RAID and NAS are two different devices. No doubt, both of these used to store essential data as they are reliable and there is less chance of data loss. Nas and Raid are extremely sophisticated and hard when to recover data in case of data loss which is why you need professional NAS data recovery company in case that happens. While there are also many changes in these two devices. Here we bring a brief comparison between these two devices and tell you about the best RAID for NAS.

Redundant Array of Independent Disks (RAID):

A redundant array of independent disks which is generally known to be as RAID is a fusion of disk arrays that are resultantly operating as one super drive. As time passes, there is a need for more and more space to store your data for which you must need multiple storage devices. That is the point for which RAID designed and made. Yes, you are reading right, as it develops in such a way that it will give you maximum performance and redundancy in data storage. Adding more and more drives for the storage purpose would become a hectic and costly process. But you don’t have to worry anymore as RAID is here for you with much cheaper compared to other storage environments like JBOD. What else should one need? Moreover, the RAID can also deploy into two main types. One type is called a hardware raid, which you can call as raid-on-chip, and the other type is known as software raid, which you can request to be an as software-only or hybrid raid.

Software RAID Vs Hardware RAID: A Tutorial | Liquid Web

What is RAID?

RAID (or a Redundant Array of Inexpensive Disks) is a way of storing logical data across a medium which is composed of multiple physical hard disk drives blended into one or more logical units or volumes that is used for data redundancy, performance improvement, and reliability.

In this article, we will review what a RAID is, what it consists of, its types (Software and Hardware RAID), storage methods as well as their advantages and disadvantages.

In a specific sense, RAID uses an array of several drive disks which creates a fault-tolerant and high-available arrangement of disks using mirroring or striping. Mirroring is defined as storing files on a set of drives in the server that have been copied in an identical manner across several drives. Striping (or alternation) is defined as storing split files into multiple parts which alternate across the disks. In some RAID configurations, both mirroring and striping is used.



Striped and Mirrored

The distinctions in the ways of using mirroring, alternation, and parity management define different RAID levels. Let’s overview them:

  • RAID 0 – productive disk array with file alternation but not failure tolerant
  • RAID 1 – mirroring disk array
  • RAID 5 – disk array characterized by block-level striping and an absence of dedicated parity disk
  • RAID 10 – RAID 0 array made of RAID 1 arrays

There are several other RAID levels, but the most popular are listed here. RAID arrays are very popular in designing SAN’s or NAS devices.

What is RAID Parity?

Certain RAID methods use what is called a parity bit which is a common method of error detection during the transmission and storage of data on the array. Parity adds a checksum to the data being shared to a target drives to ensure the data is as close as possible to be indistinguishable from the data on source drives. RAID 5 primary uses parity in its methodology.

Software RAID

It’s important to remember that a RAID controller is at the core of the RAID system. It plays a vital role in data distribution among RAID disk arrays including both Software and Hardware RAID.

Software RAID uses the functionality of the RAID software or the RAID driver built in to the servers operating system. This method does not require any additional equipment to connect storage devices. It can however increase the overall processing load on a server and possibly slow RAID calculations, and other processes being carried out on the device.

Many server operating systems support RAID configuration, including ones from Apple, Microsoft, and various versions of Unix/Linux systems. Quite often, Software RAID depends on the operating system being used, so it’s not recommended for the divisions which are shared by multiple operating systems.


  • Most operating system support RAID Software configurations which makes it easier to set up and accomplish configuration tasks which solves different issues
  • Software RAID installation is much cheaper as it does not require and additional hardware equipment
  • Software RAID is mainly suitable for processing simple RAID 0, RAID 1, and RAID 10, which does not cause additional system load
  • We can implement a RAID configuration on one operating system (e.g. Ubuntu) and use it across other like systems
  • RAID level re-configuration is possible as the settings are flexible and not complicated.


  • Software RAID can significantly influence general system load while carrying out a complicated RAID configuration
  • Software RAID implementation is not useful if there are multiple drivers installed on the system, as some conflicts could occur
  • Some operating systems support only a limited type of levels of RAID (such as RAID 3, 4, 6, 50, 60, etc.)
  • There is limited opportunity to use RAID on a clustered operating system
  • Software RAID can be vulnerable to viruses and other malware as it operates within the primary servers operating system
  • System failures on the server can have a negative influence on data integrity
  • Replacement of failed disk can be complicated

Having looked into Software RAID and some of its advantages and disadvantages, we can conclude that this method can be used for small projects with a limited budgets and when computing power, maximum data safety, and speedy data and disks recovery are not priorities.

Also, it’s essential to keep in mind that these are only general recommendations as the choices will depend on project needs and the tasks which are required to be accomplished.

Hardware RAID

Hardware RAID is the method where all the drives are connected to a hardware RAID controller, which is on a separate RAID card, different server, or built into a motherboard. Hardware RAID controllers physically manage RAID arrays, configurations and support multiple RAID levels. In some cases, the RAID controller can act as a mini version of a computer as they come with dedicated processors to carry out their tasks.

During the Hardware RAID installation process, drives connect to the RAID controller board. This applies not only for large servers but also for desktop computers. Processing Hardware RAID refers to discrete controllers (such as ATA RAID, SATA, DELTA PLC, etc.) on the level of the disk’s storage system.

Because the RAID is managed by and processed on the controller board, there is no additional load on the server processor. Utilizing Hardware RAID also has many other extended functionalities, including a hot swap disk option in case of any one single disk failures. Additionally, Hardware RAID is more expensive than Software RAID, but it has higher productivity and functional compatibility.


  • High level of system productivity is especially essential for old systems with limited resources to increase computing power
  • Hardware RAID uses its cache-memory for making a backup copy and data recovery
  • There are fewer issues with RAID systems during the creation of a backup copy and data recovery
  • Flexibility while configuring RAID, which is complicated to realize without equipment
  • Protection from data loss and corruption may occur if there’s a power outage during the creation of a backup copy as Hardware RAID uses backup batteries and its built-in flash memory
  • Works well on all types of disks
  • Easy to move the box between computers, servers, and OS
  • Compatibility with various OS
  • Additional RAID levels (such as RAID 5, 6, 50, 60) can be used; however, they require more resources

FAQs On a Udemy clone app That You Should Know Before Buying!

BSETEC's Udemy clone app based on formalized teaching but with the help of electronic resources is known as E-learning.E-learning, also referred to as online learning or electronic learning, is the acquisition of knowledge which takes place through electronic technologies .

Udemy, which was founded more than a decade ago, has established itself as a global leader in the online teaching industry. People in our digital era rely on technology and devices for nearly everything, including education. When it comes to online learning, or eLearning, which is regarded as a lifesaver– capable of sustaining the educational environment even during the Covid-19 pandemic– it has evolved into a platform bursting with potential, not only for students but also for tutors, educators, and instructors. Furthermore, when compared to traditional educational techniques, the flexibility and customization given by online tutoring software like Expertplus LMS are unrivalled. As a result, it is gradually becoming an important component of the learning process, which is why eLearning is here to stay– even after the epidemic has passed, it is a huge increase in the number of eLearning applications and websites, and most businesses are choosing for Udemy Clone App instead of starting from scratch.

BigBlueButton Technology – Make Efficient Interaction with LMS

How can I get started with your own online tutoring company?

To use the Udemy Clone App script to establish an online tutoring marketplace similar to Udemy, bear the following factors in mind:

  • How to define your target audience?– Before you start developing your Learning Management System, you should think about who you're going to serve, what their background is, what kind of job they want to do, and what their career goals are. These are all things to consider before you begin the development process. As a result, you must be clear about who you are developing your app for.
  • Why have a clear set of goals and objectives in mind?– If you're creating an app for eLearning, you should have a solid strategy and set of goals in mind. You can't simply take a leap of faith and draw conclusions. You must have both long and short term objectives, and you must put them into action.
  • Why create a simple and speedy registration process?– No one wants to spend more than a minute or two on a signup screen, especially if the app is intended for educational reasons. As a result, it's critical that the user registration, login, and signup procedure be simple and quick. It should provide one-tap or social login options so that the AI can read the social account and fill in the data on its own.
  • Why have a visually appealing homepage– "The first impression is the final impression" and "The last impression is the enduring impression" are two prominent expressions. When you initially open the app, the first thing that appears on your screen is the homepage, and if it isn't appealing enough, you will most likely not want to use it. As a result, the user interface must be simple to use and appealing to the eye.
  • Why do we alter and revise– Once you've begun creating the app, you can customise and revise it to meet the needs of your users, thanks to the Udemy Clone Script's high level of customization and a large range of templates and motifs to select from.

If you want to develop a platform with high-quality eLearning features that cater to the needs of a large mass of audience, then opt for ExpertPlus LMS, and contact BSEtec now! Hurry!
