What is nas?

NAS (Network Attached Storage) is a smart storage device that connects to a home or office network. NAS allows you to access your files from any computer or mobile device, as long as it is connected to the same network. Basically, a NAS connects multiple storage devices (such as hard disk drives) to the network.

Think of a NAS just like cloud storage like Google Drive or Dropbox, but hosted or stored in your home. It can be said that a NAS is a special type of file server, so it can be accessed simultaneously by many devices and users.

Equipped with a hard disk, its own operating system and management software, the NAS is tasked with storing and sharing files on the network.

A NAS is built into complete hardware, and even a NAS also has built-in software or applications that can be used to store, backup, and share data. So with this device, you no longer need third party apps because the same default app is already available.

Even with the right network configuration, you can make your NAS device accessible online to create your own cloud storage server.

Why do I need a NAS?

There are several reasons why you need a NAS in your home. Say, for example, that you need to regularly backup photos from several smartphones and cameras.

The usual process when backing up photos is to connect each device to your computer and copy the files. When someone in the family requests a copy, you must connect their storage device to the same computer or use an online service such as email.

Although the above is good for infrequent or infrequent image transfers. But with a NAS, you can make this routine easier. First, it removes dependence on your home computer. Secondly, it also offers automatic backup and wireless transmission options to simplify the whole process.

A NAS can also be useful for collaborative tasks such as editing documents and videos. If each user has their own copy of the file, any changes made to the file will not be synchronized with other users. However, when working directly from your NAS volume reduces this issue as all users access the same copy or file.

You need to know that NAS offers more efficient performance than DAS (Direct Attached Storage) in some cases, especially when multiple devices need access to storage. When dependent on network traffic factors and storage communication protocol preferences, NAS may also be more efficient than a SAN for some workloads.

What are the benefits of using a NAS?

NAS systems are popular with organizations and small businesses across many industries as an efficient and cost-effective storage solution. They can be used to support email systems, accounting databases, payroll, video recording and editing, data logging, business analytics, and more. A variety of other business applications are supported by the NAS system.

Due to the flexibility and popularity of NAS systems, most cloud service providers also offer NAS services that allow the mixing and matching of NAS storage systems and cloud services within the business, enabling cost, management efforts, and performance optimization while giving the business complete control over location and security. Here are some of the benefits of using a NAS:

  • It is easy to operate and there is no need for IT professionals to operate it.
  • Save cost.
  • Easily backup and restore data with detailed security features.
  • Centralize data storage in a secure and reliable manner for network users and authorized customers.
  • Supports a variety of applications.
  • It allows access to data over the network, including applications and cloud-based data.

conclusion

So what is a NAS? A NAS is a network-attached file-only storage device that allows access to data from multiple users and specific access devices. This tool frees the server from the task of storing and sharing files, and has better scalability due to its standalone nature.
