Let us see which approach is best for your storage needs.

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.

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.

Expert opinion: NAS, cloud, or a hybrid approach?

To understand which data storage solution is best suited for various needs, it is helpful to consider insights from Frank from Learning and Technology with Frank. Frank runs a successful YouTube channel that helps individuals leverage technology for self-development, education, and the goal of making themselves and the world better.

As an expert in learning and technology, Frank frequently encounters the question: Should organizations choose NAS, cloud storage, or a hybrid approach? Each option presents unique advantages and challenges that organizations must consider based on their specific requirements.

When to choose NAS

Network Attached Storage (NAS) is a strong contender for organizations that prioritize fast, local access to their data. Frank observes that “NAS systems provide a robust solution for storing large amounts of data on-site.” This is particularly beneficial for businesses handling sensitive information with stringent security protocols. 

Storing data locally significantly reduces the risk of unauthorized access over the internet. Moreover, NAS devices typically come with “built-in backup and redundancy features,” ensuring that data remains intact even in the event of hardware failures.

When cloud storage is the better option

On the other hand, cloud storage offers remarkable flexibility and scalability. One of the most compelling aspects of cloud solutions is that “organizations can easily adjust their storage capacity based on real-time needs,” according to Frank. This is especially advantageous for companies experiencing rapid growth or fluctuating data usage. 

With cloud storage, employees can access data remotely, which is critical in today’s increasingly remote work environment. 

However, Frank cautions organizations to consider potential downsides, such as “the reliance on internet connectivity and concerns over data privacy and control.” You need to weigh these factors against the benefits of convenience and scalability.

Hybrid solutions for the best of both worlds

The hybrid approach strikes an excellent balance between the two. Frank believes that a hybrid model allows organizations to keep sensitive data stored locally while leveraging the cloud for less critical information or backup solutions. 

However, while hybrid solutions offer flexibility, they also introduce added complexity and overhead. Managing both on-site and cloud storage systems requires additional resources and can increase costs, especially if cloud services are used for large datasets. In some cases, the cloud’s subscription fees can outweigh the benefits for businesses dealing with substantial volumes of data.

Despite these challenges, a hybrid solution enhances disaster recovery capabilities by ensuring data is safe and recoverable from multiple locations. 

Ultimately, the best choice depends on each organization’s unique circumstances, including existing infrastructure, budget considerations, and long-term goals. 

Frank often advises his audience, “Engaging with IT experts and assessing current and future data storage needs can help guide you toward a solution that enhances operational efficiency while meeting security standards.”
