What Is NAS?
NAS (Network Attached Storage) is a dedicated device connected to your home or office network, allowing multiple devices to:
- Store and access files centrally
- Stream media to any device
- Back up data automatically
- Share storage across your household or team
Think of NAS as your private cloud — hosted in your own home.
NAS vs. Cloud Storage: The Hidden Costs
Cloud storage providers often highlight convenience, but they rarely mention:
Cloud Storage
- — Monthly fees that compound over time
- — Ongoing price increases
- — Bandwidth limits and throttling
- — Egress fees for business users
NAS
- — One-time hardware cost
- — Full control over your data and privacy
- — Faster local transfer speeds
- — No surprise charges for your own files
The Real Cost of Cloud vs. NAS
Storing 40TB for 5 years in the cloud can easily cost more than:
- A high-quality NAS enclosure
- Four 16TB NAS-rated drives
- Redundant backup drives
Cloud is convenient. NAS is ownership.
When Should You Use a NAS?
NAS is ideal for:
- Media servers (Plex, Jellyfin, Emby)
- Home backups — automated, secure, and private
- Photography and video archives
- Small business storage (collaboration without cloud fees)
- Long-term archival — no risk of provider shutdowns or data loss
Best NAS Drives: What to Buy (And What to Avoid)
Use
- CMR drives only
- NAS-rated or enterprise drives
- 3.5" drives for best bulk value
Avoid
- SMR drives in RAID arrays
Final Thought: Is NAS Right for You?
If you value privacy, control, and long-term savings, NAS is a smart investment. Cloud storage is renting. NAS is owning.
