Detailed Introduction to NAS (Network Attached Storage)

The explosive growth of data and the resulting security issues have become a new challenge. The rapid growth of data has undoubtedly brought unprecedented challenges to SMBs and professionals, so more and more enterprises and professionals are turning to NAS network storage, using NAS for data backup to quickly recover data and minimize losses in case of accidents.

What is NAS?

NAS is Network Attached Storage. NAS is a private network disk or private cloud disk, which can realize the function of backup and sharing of files, photos and videos from cell phones, computers, and other storage terminals through NAS.

NAS can be defined to refer to the hardware involved and its technology. NAS devices, on the other hand, are individual units that perform operations.

You can think of a NAS as a centralized storage system where connected devices can be accessed through a browser-based utility. This means that the NAS does not require a monitor or keyboard to be connected. To access it, you need to use a networked device.

In addition to NAS, there are Storage Area Networks (SANs). Unlike a NAS, a SAN handles structured data (block storage). Next is the direct storage device (DAS), which is not connected to the network and requires direct access to the storage. Each storage type has its advantages and disadvantages, which we will discuss later in this article.

When do you need a NAS?

What do you do when your data volume has exceeded your desktop hard drive storage capacity and you want to share access to files and media from multiple computers, phones, and tablets? For prosumers, creative professionals, small businesses, and families, the solution is a network-attached storage (NAS) device, the easiest to set up and the best value-shared storage option.

Unlike plugging a device directly into a computer via a USB cable, NAS systems connect to a wireless router or an Ethernet port on the network. This allows multiple computers and mobile devices on a network to wirelessly share and access files, stream video, and audio, and back up computers and mobile devices from a central device. a NAS solution consists of multiple components, including hardware (one or more hard drives encased in a hard drive enclosure, processor, and RAM) and software (consisting of an operating system that manages access and network connectivity).

NAS Build Solutions

NAS as a storage system has a relatively simple composition, generally consisting of two parts: storage hardware (hard disk or raid disk array, also CD/DVD drives) and operating system (Linux/Windows).NAS is usually connected to the LAN port of a network terminal and has a private IP address assigned by the server, allowing users to access data through that IP address. NAS is usually connected to the LAN port of a network terminal and has a private IP address assigned by the server, allowing users to access data through that IP address to fulfill their convenient network private cloud storage needs.

A simple home NAS consists of only a mini NAS device and an APP, which contains the hard disk, drive, operating system, and exclusive IP address, while the APP contains the access portal and data management functions. The home NAS solution is relatively simple to set up, take Greenlink NAS as an example: plug in the power, connect the NAS to the LAN port of your home router through the network cable (or WiFi connection), search and download the “Greenlink Cloud” APP in the Android/Apple store, then follow the APP prompts to scan and pair the NAS to complete the setup. The subsequent system upgrade, user management, and file management can be done through the APP interface.

Advantages of NAS storage

NAS storage positioning determines the configuration of NAS on the server side will be greatly simplified, NAS does not need the traditional service system complex operating system but uses a simple operating system designed for personal users, dedicated to data storage, built-in network connection protocol, system management, and setup is more simple.

  1. Low loss and high efficiency

NAS is a device directly connected to the network media to achieve data storage, its operation and maintenance costs are very low compared to traditional storage servers, and NAS private cloud storage is for personal and home users, user needs and use scenarios are more unified, the corresponding NAS data management functions are more targeted, data application efficiency.

  1. Simple and easy to deploy

NAS storage solutions can be built with just one set of storage hardware and a simple operating system, making personal and home NAS very easy to deploy.

Now the integrated NAS service provider will pre-install the hard disk and operating system, users only need to get a NAS box, and then install an APP on the phone, you can build a perfect home NAS private cloud storage solution, very easy to deploy.

  1. Easier data sharing

As NAS devices come with exclusive IP addresses, users can access the IP address to achieve file management. NAS can achieve data sharing anytime and anywhere, as long as there is a network, data access can be independent of long-distance and LAN mode restrictions, and mobile storage and off-site storage can be easily accomplished. For example, we put NAS devices at home, then in addition to the home, it is also possible to manage data in the office or outdoors via a mobile APP, and multiple family members can also share data in real time, which is very convenient.

Disadvantages of NAS storage

Although Network Attached Storage (NAS) has many advantages, it also has some disadvantages that are worth considering. Here are some of the main disadvantages of NAS:

Cost: NAS devices can be expensive, especially if they have large storage capacities or advanced features. In addition, some NAS devices require additional licensing fees to use certain features, which can add to the overall cost.

Limited Performance: NAS devices are not as powerful as dedicated servers or desktop computers, so they may not be able to handle certain tasks that require a lot of processing power or resources. This can lead to slower data transfer speeds, especially when multiple users are accessing the device simultaneously.

Dependence on Network: Since NAS devices are connected to a network, they are dependent on the network for their performance. If the network is slow or experiences downtime, the NAS device may be impacted as well, which can cause data access and transfer issues.

Security: NAS devices can be vulnerable to security threats, especially if they are connected to a public network or not properly secured. This can lead to data breaches, data loss, or other security issues.

Compatibility: Some NAS devices may not be compatible with certain operating systems or software, which can limit their usefulness in certain environments. It is important to check for compatibility before purchasing a NAS device.

Overall, NAS devices can be a convenient and useful tool for storing and sharing data on a network, but they do have some limitations that should be taken into consideration when deciding whether or not to use them.
