What is NAS?

NAS vs Cloud vs Direct-Attached Storage

Not all storage solutions are built to scale with your needs. Public cloud services may offer convenience, but often at the cost of ongoing fees, limited control, or security trade-offs. And while direct-attached storage (DAS) works for one device, it falls short when multiple users or remote access are required.

Network Attached Storage (NAS) offers a flexible, scalable alternative — putting your data under your control while enabling remote access, multi-user collaboration, and integration with select cloud environments for added redundancy and backup protection.

How It Compares

Feature	NAS Storage	Personal Cloud Storage	Direct-Attached Storage (DAS)
Remote Access
User Permissions
Encryption Support	(WD Red + NAS OS)	Varies	On select drives
Scalability	High	Medium	Low
Subscription Needed	One-time hardware cost	Often	N/A
Ideal For	Home, business, creative teams	Individual sync and access	Local backups, single-device use

Looking for Simple, Plug-and-Play Backup?

If you’re just looking to back up your personal computer or store files locally, Western Digital also offers Direct-Attached Storage (DAS) solutions. These include My Book, My Passport, and more - great for fast, encrypted backup without the complexity of a NAS.
