In the modern world, there is significant data generation and consumption alongside the need for flexible, scalable, and secure storage solutions. On the other hand, self-hosted cloud services are an attractive alternative to commercial clouds. Building a private cloud may help to overcome issues with privacy, security, vendor lock-in, and the recurring costs that commercial services offer. The purpose of this research is to design, implement, and evaluate personal private clouds based on Network Attached Storage, which is powered by Raspberry Pi. It investigates the possibilities of utilizing such privacy-centered cloud storage as an alternative to mainstream services available. This paper presents a system architecture for configuring core private cloud functions with performance benchmarking and security assessment strategies. Simulated experimental results demonstrate the system capabilities alongside securing sensitive data from common threats. The findings pinpoint critical areas for further enhancement and development while demonstrating the effectiveness of the low-cost method for personal and small-group private cloud applications.
