Companies might not be able to provide the quality of service required by their consumers without access to their business data. Lack of access to corporate information may lead to poor customer service, decreased sales, or even business collapse.

However, it is also true that the majority of enterprises place more emphasis on the applications that use the storage than on the storage itself. Small firms must to deal with additional obligations, such as:

  • streamlined operation (many small businesses do not have IT staff)
  • Application and system availability, dependability, and accessibility for daily use
  • Easy to use backup, recovery, and security features to safeguard application data
  • a large selection of software are readily available to assist their company demands.

To achieve these objectives, particularly those of flexibility, simplicity, and ease of management, designers of software applications suited for smaller business environments frequently use file-based systems; in addition, there are many simple-to-use tools to provide security and reliable backup & recovery.

Instead than connecting directly to a computer, a network-attached storage (NAS) device connects to and is accessed through a network. In order to run applications and give the intelligence required for files to be easily shared by authorized users, NAS systems have a CPU and an operating system. A NAS device’s attractiveness is that it may be quickly accessible by numerous users, numerous computers, mobile devices, or even remotely (if set up properly). 

Directly to your computer:- When we require more storage than our computer or laptop can provide, the majority of us do this at home. A hard disk or SSD is often connected to your computer’s USB port using a USB cable.

Cables and ports for Thunderbolt may be used by Mac users. Although there are ways to grant others access to that hard drive, the hard drive is often only used by the computer to which it is attached. Direct-attached storage is another name for it (DAS).

Via a network:- We’re referring to your local network, which could be a WiFi-enabled network or a hard-wired ethernet network, at your place of business or at home. Network-attached storage, or NAS, refers to storage devices that are linked to networks, as was previously described. Although you can typically set up access to your NAS devices through the internet, should you so want, NAS devices are typically configured for access via permissions to users on an internal network. Although the third way to connect computers and information, as indicated below, may be argued to be cloud storage in a wide area network (WAN), for the purposes of this article, we’ll stick to a local network.

Cloud storage:- Network-attached storage options include Azure, Amazon Web Services, iCloud, and many others. However, for the purposes of this discussion, we’ll just talk about local networks. In order to access their data and files during internet failures, to keep expenses stable or predictable, or out of concern for their privacy and data security, most users choose to attach storage to their own networks

How a NAS Device Operates

Compared to network devices, your computer will read data from and write (store) data to DAS devices more quickly. You might see a difference, depending on the size of your files and what you’re attempting. Using DAS is often useful when editing large images or films, working with intricate design papers, or transporting very large data. Although NAS read/write performance is slower than DAS external storage, NAS devices are more advanced. NAS devices have a number of components built into their architectures to accommodate the range of ways users desire to use network-attached storage

Storage:- A NAS device’s main purpose when using a hard drive is typically to store your files. Two to five hard drives are found in the majority of NAS devices used by home offices, small businesses, and enterprise workgroups. In addition to having a larger storage capacity than a single hard drive, several hard drives can also offer redundancy and quicker file access and storage times. 3.5-inch hard drives with a particular NAS category are commonly used in NAS devices since they can withstand the demands of an always-running device.

Networking:- The NAS device is linked to your computer in this manner (s). Either Wi-Fi or an ethernet cable (hardwired) can be used to connect to the network. Despite the fact that many NAS devices have USB ports, these ports are not used to connect the NAS device to your computer. Instead, you connect other devices to your NAS device using these USB ports, whether it be for charging, backing up, or other data transfers.

Computer/CPU:- In order to manage the filesystem, read and write operations, run applications, process multimedia files (such as video), handle many users, and, if desired, integrate with the cloud, NAS devices must have some sort of CPU.

Operating System:- Although the typical user may not realize that an operating system controls the storage device, NAS systems are required to have an OS in order to handle the functions that would typically be handled by a computer for DAS devices. Additionally, the operating system is required to operate the several applications that are accessible on NAS devices:

  • Business software, including CRM and ERP
  • transcoding and serving of multimedia
  • Tools for increasing productivity, such as spreadsheets, documents, and email.
  • Applications for teamwork and file sharing
  • integrating public and private clouds
  • Web servers
  • Software development

If a NAS device is right for you, you should assess your storage capacity needs, capacity growth potential, the acceptance of its operating system or management software, the availability of application packages, and how powerful the processor needs to be (based on the applications you may want to run).

Advantages of NAS

  • Simple to operate
  • Compared to other storage methods, it is less expensive and can greatly minimize wasted space.
  • With granular security features, data backup and recovery is simple.
  • centralization of data storage for authorized network users and clients in a secure manner
  • enables a wide range of uses
  • enables access to data across the network, including data and applications stored in the cloud.
