A Raspberry Pi NAS won’t match a purpose-built Synology or QNAP on raw performance, but it is a genuinely capable, low-cost option for basic file storage and backup for a household or small home lab.
A Raspberry Pi 5 for real USB 3.0 throughput
Pi 5’s proper USB 3.0 controller (rather than the shared bus older Pi models used) makes a real difference for NAS use specifically, where sustained drive throughput matters more than most other Pi projects.

- Raspberry Pi 5 with 8GB RAM: Model SC1112 featuring a quad-core ARM Cortex-A76 processor running at 2.4GHz. Enhanced Connectivi…
A powered USB drive enclosure or HAT
Drives need reliable, adequate power delivery independent of the Pi itself — a proper powered enclosure or NAS HAT avoids the flaky behavior unpowered USB drive setups are known for.

- Package Include: 1pcs* RPI4 Quad Sata Hat Kit Network Storage Server
- A Nice lean design, Smaller than a bottle of Coke, fits into the smallest book shelf
- High Capacity : Up to 16TB, with low noise PWM fans
Reliable NAS-rated hard drives
Standard desktop drives aren’t built for the constant read/write cycles of NAS duty — NAS-rated drives are worth the modest price premium for a build meant to run continuously.

- Available in capacities ranging from 2TB to 12TB
- For RAID-optimized NAS systems with up to 8 bays
- Designed for Continuous Operation
Run OpenMediaVault or a similar purpose-built NAS OS rather than configuring Samba shares manually — it handles the RAID, permissions, and share management in a much friendlier interface.
