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.
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.

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

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.
Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.
In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.
A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.
And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.
Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.
It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs.
