A simple, secure, and private home network storage system built using a Raspberry Pi and Samba (or OpenMediaVault). This project is perfect for makers who want a personal “cloud” drive accessible from any device in their home — without paying monthly fees or relying on third‑party services.
Quick Verdict
If you want a private, always‑on storage solution for photos, videos, and backups, a DIY Local Network Storage System is a fantastic project. It gives you full control over your data, works with any PC or phone, and costs far less than commercial NAS devices.
But if your goal is plug‑and‑play simplicity, pre‑built NAS units like the Synology DS120j or WD My Cloud Home are easier to set up and include built‑in apps. DIY is for flexibility and learning. Pre‑built is for convenience and polish.
What You’re Building
A compact, low‑power network storage system that:
- Keeps your data private and offline
- Shares files across all devices on your home Wi‑Fi
- Acts as a backup drive for photos and videos
- Can stream media to TVs and consoles
- Runs 24/7 with minimal power use
- Uses open‑source software (Samba or OpenMediaVault)
Parts List
| Component | Purpose |
|---|---|
| Raspberry Pi 4 (4 GB or 8 GB) | Main system |
| 128GB microSD card | OS + boot storage |
| External USB drive (1–5 TB) | Main data storage |
| Case + heatsinks | Cooling + protection |
| 5 V 3 A power supply | Stable power |
| Ethernet cable | Faster file transfers |
Tools Needed
- Computer with SD card reader
- Raspberry Pi Imager
- Internet connection
- Optional: small screwdriver (for case assembly)

Step‑by‑Step Build Guide
1. Flash the OS
Use Raspberry Pi Imager to install OpenMediaVault or Raspberry Pi OS Lite onto your microSD card.
2. Assemble Your Pi
Install the case, heatsinks, and insert the microSD card.
3. First Boot
Connect Ethernet → power on → wait for the Pi to boot. Find its IP address using your router or the arp -a command.
4. Install Storage Software
If using Raspberry Pi OS, install Samba:
bash
sudo apt update
sudo apt install samba samba-common-bin
If using OpenMediaVault, access the web interface at http://<your_pi_ip>/ and follow the setup wizard.
5. Mount Your External Drive
Plug in your USB drive and mount it under /mnt/storage or through OpenMediaVault’s “File System” tab.
6. Create Shared Folders
Set up shared folders for:
- Photos
- Videos
- Documents
- Backups
Enable SMB/CIFS access so Windows, macOS, and Android devices can connect.
7. Test Access
From any PC, open File Explorer and type:
Code
\\raspberrypi\storage
Enter your username and password — your home cloud is live.
Tips & Notes
- Ethernet is faster than Wi‑Fi for large transfers
- Use a powered USB hub for multiple drives
- Enable automatic backups with rsync or Time Machine
- Add a small fan if your Pi runs warm
- Keep your data safe with periodic external backups
