Introduction to NAS and cloud storage

First, we’ll define each option and explore the key differences between them.

What is NAS?

Network Attached Storage (NAS) is a device connected to a local network, designed to store and retrieve data from a centralized location. NAS systems often use RAID configurations to ensure data redundancy and performance. They offer expandable storage, which makes them popular with home users and small businesses.

For Home Users, NAS provides centralized storage for media streaming, file access, backups, and secure remote access, making it easy for a family to organize personal data.

For Businesses, NAS provides secure, centralized file storage, ensuring easy backup and controlled access to sensitive data.

What is cloud storage?

Cloud storage is a method of storing data online instead of on a local device. It is often hosted by third-party providers like Google Drive, Dropbox, and Microsoft OneDrive. It has become a popular choice for SMBs and enterprises due to its ease of access, scalability, and minimal setup.

Data in the cloud is stored on remote servers and accessible from any internet-connected device, offering flexibility for users who need data access across multiple locations. This makes it especially beneficial for remote work and global collaboration.

Unlike NAS, cloud storage is ideal for individuals and businesses prioritizing accessibility, quick scalability, and automated backups. 

NAS vs cloud: key differences

	NAS	Cloud Storage
Data access and control	Local control High-speed access within the local network Remote access requires setup	Less direct control over physical storage Remote access from anywhere with internet
Cost	Upfront hardware costs No monthly fees Cost-effective for large, long-term storage	No upfront hardware cost Monthly/annual subscription fees More costly over time for high-capacity use
Security and privacy	Data stored locally Customizable security Risks of ransomware without safeguards	Provider-managed security (encryption, MFA) Vulnerable to data breaches
Backup and disaster recovery	RAID configurations for redundancy Needs offsite backup for full disaster recovery	Provider-managed backups with multi-location copies Easy file recovery but internet-dependent

Let us learn more about NAS storage vs Cloud.

Data access and control

NAS: You manage your data locally, with everything stored on hardware within your network. This setup provides fast access, perfect for sharing and streaming within your local network.

Cloud storage: Designed for remote access, cloud storage hosts data on third-party servers, letting you retrieve it from any internet-connected device. This flexibility, however, also means that you rely on the provider’s servers to access your data.

Cost comparison

Cost differences become clear when you compare NAS components (device, drives, electricity, and backup costs) with cloud storage (subscription fees and file storage costs). For example:

Cloud storage (e.g., iCloud): For 2TB, iCloud costs $10/month or $120/year. Higher storage needs, like 6TB, increase to $30/month ($360/year). Adding an external drive for backup may cost an additional $150 upfront. This setup is cost-effective for users with smaller storage needs but can become costly for long-term, high-capacity storage.

NAS: A NAS setup, like a DS223 with drives, totals around $850–$1100 initially, lasting approximately five years (averaging $170–$220 annually). While it requires an upfront investment, NAS can prove more economical over time for larger data volumes.

As a Reddit user noted, “For small amounts of data (a few hundred GB to 1TB), the cloud is probably cheaper and certainly more convenient. For larger amounts (10 to 100TB), the cloud gets VERY expensive, and the break-even duration is probably less than 2 years.”

Security and privacy

NAS: Data stays local, which allows you to customize security measures, like RAID redundancy and encryption. However, you must secure it against ransomware, especially if accessed over the internet or if any device connected to the NAS is online.

Cloud storage: Providers typically offer robust security features, such as encryption and multi-factor authentication. However, data breaches remain a risk since data is stored online, and privacy concerns may arise for users wary of third-party data handling.

Backup and disaster recovery

NAS: Provides on-site backups and redundancy through RAID, though an off-site backup (such as to the cloud) is recommended for complete disaster protection.

Cloud storage: Often includes multi-location backups and quick recovery options, which safeguard data against physical damage to user devices. For large file sets, though, restoring can be slower compared to NAS due to internet dependency.

TIP: When planning for backups and potential incidents, don’t forget to set up reliable cloud monitoring to keep an eye on your server. Tools like UptimeRobot can notify you immediately when your attention is needed.
