I. INTRODUCTION

In today's digital era, data storage and management have become essential for individuals and businesses. Traditional cloud storage services are expensive and require a constant internet connection, making them unsuitable for users who need cost-effective, private, and customizable storage solutions. Commercial NAS (Network Attached Storage) systems provide reliable data management but come with high costs and limited flexibility. Many small businesses, educational institutions, and personal users require an affordable alternative that allows them to store, share, and access data securely within a local network without depending on third-party cloud providers.

To address these challenges, this project focuses on the "Development of a Cost-Effective, Custom-Built Network Attached Storage (NAS) System." The proposed NAS solution will utilize mid-range hardware and open-source software to provide a scalable, secure, and easily accessible storage system. Unlike traditional NAS devices, this system will offer enhanced security through blockchain integration, mobile auto-backup, voice command operations, and web hosting capabilities. The goal is to provide an efficient and budget-friendly NAS system that meets the growing demand for personalized, high-performance, and decentralized storage solutions.

II. LITERATURES REVIEW

Network Attached Storage (NAS) has emerged as an essential technology for small businesses and individuals looking for cost-effective and scalable storage solutions. Traditional NAS systems were often expensive and required dedicated hardware, making them inaccessible for startups and budget-conscious users. Recent research has explored cost-efficient NAS designs that integrate cloud-based storage to optimize performance while reducing expenses [1]. Studies have also highlighted the advantages of energy-efficient NAS architectures, which consume significantly less power while maintaining high-speed data access, making them ideal for small office environments [7]. Security remains a crucial aspect of NAS technology, particularly for businesses handling sensitive data. Various encryption techniques and blockchain-based authentication systems have been proposed to enhance NAS security and prevent unauthorized access [8]. One study demonstrated that integrating blockchain into NAS systems improved data integrity and reduced security breaches by 15% [6]. Additionally, RAID configurations have been widely implemented to provide data redundancy and mitigate the risk of hardware failures, ensuring continuous data availability [5].

With the widespread use of mobile devices, NAS systems have evolved to support automatic backups and remote data access. Research has demonstrated that NAS solutions with mobile integration significantly reduce the risk of data loss by automating backup processes without requiring user intervention [2]. Furthermore, hybrid cloud-based NAS solutions have gained popularity due to their ability to combine local storage with cloud accessibility, allowing businesses to maintain real-time data synchronization while optimizing storage costs [12].

Recent studies have also explored the application of NAS in remote work and surveillance systems. Businesses adopting NAS for remote collaboration have reported increased efficiency due to centralized document management and seamless file sharing [13]. In surveillance applications, NAS has proven to be a reliable and cost-effective solution for storing large volumes of security footage, reducing overall storage expenses by 30% compared to traditional storage methods [9]. These advancements highlight the growing relevance of NAS technology in diverse domains, emphasizing its role in improving data security, accessibility, and cost efficiency.

III. METHODOLOGY

Our project is a custom-built NAS system utilizing TrueNAS for storage management and NextCloud for remote access and collaboration.

A. NAS System Architecture

Figure 1: NAS System Architecture

The NAS system architecture consists of key components, including a CPU, RAM, and a storage controller that manages various storage devices such as HDDs, SSDs, and USB drives. The system is powered by an external power source, ensuring stable operation. The CPU and RAM work together to process data requests, while the storage controller handles data allocation and retrieval. This setup enables efficient storage management and high-speed access to stored files

Figure 2: Custom Build NAS system

For data access and user interaction, the NAS is equipped with a network interface (LAN/WiFi) that facilitates communication with external devices over WAN/LAN. Users can access files and manage data through a web interface, APIs, SMB, or NFS protocols. The system can also be connected to the internet for remote access, ensuring seamless data availability. This architecture supports both local and remote file access while maintaining security and performance.

The implementation of our NAS system follows a structured workflow to ensure efficient setup, functionality, and usability. It begins with hardware and software installation, followed by network configuration, feature integration, and final deployment.

1) Step 1: Hardware & Software Setup

Hardware:

• Processor: Intel i3-6th Gen
• RAM: 8GB DDR4
• Storage:
  • 128GB SSD for OS and software operations (faster performance)
  • 500GB HDD for user data storage

Software:

• NAS Software: TrueNAS installed as the base storage management system
• NextCloud: Integrated for web-based file access and sharing

As shown in Figure 2, the initial step involves selecting and assembling the hardware components, followed by installing TrueNAS as the primary operating system. NextCloud is configured to provide seamless file-sharing capabilities.

2) Step 2: Network Configuration & Access

The NAS system is initially connected to the home router, where a static IP is assigned to ensure stable and predictable access. This setup enables seamless communication within the local network, allowing users to transfer data and manage files efficiently.

Additionally, SSH Access is configured to allow remote administration. This ensures that system configurations and troubleshooting can be done securely without needing direct physical access.

To enhance the system’s autonomy, it is configured as an independent access point, eliminating dependency on an external router. The NAS will function as a DHCP server, allowing devices to connect directly to it without an intermediary network. WPA2 security is enabled to protect direct connections.

3) Step 3: Storage & Partitioning

The storage system is structured to ensure optimal performance and efficient data management. The 128GB SSD is dedicated to the operating system, TrueNAS, and essential software operations, ensuring a fast and responsive system. Meanwhile, the 500GB HDD is designated for user data storage, supporting:
