Network-attached storage and storage area networks enable stored data to be accessed by many users simultaneously. But what is a network-attached storage (NAS), and how does it stack up against a storage area network (SAN) solution in terms of storage features? Here we’ll define and compare the two to determine the best storage type for work in the cloud.


What is Network-Attached Storage?

The term “Network-Attached Storage” (NAS) refers to file-level storage devices and servers connected to a network that provides data access to many users. A NAS system connects via a local area network (LAN) and has redundant data structures. It is an affordable, easy-to-maintain network storage solution.


What is Storage Area Network?

A “Storage Area Network” (SAN) is a dedicated network of storage devices that enables shared storage, appearing to users as if the storage was directly connected to their computers. A SAN uses Fibre Channel for connection and switches to manage storage data traffic. The system is designed for quick, low-latency data access and easy scaling.


Comparing NAS vs. SAN

Below is a comparison of the features of NAS and SAN:

Feature NAS SAN
Network Connects via a LAN Runs on high-speed Fibre Channel
Data Processing Processes file-based data Processes block data
Protocols Uses several different protocols to connect with servers, such as NFS, SMB/CIFS, and HTTP Uses the SCSI protocol
Scalability Not highly scalable Highly scalable
Performance Slower throughput and high latency High-speed data access with low latency
Cost Less expensive to purchase and maintain More expensive due to complex architecture
Management Easy to set up and manage Requires hands-on administration to configure and manage
Backup and Recovery Uses traditional network-based backup Enables swift backups without bottlenecks


Uses Cases for NAS and SAN

Network-Attached Storage (NAS)

Depending on your company's requirements, NAS can be a better choice:

  • Data analytics: NAS is the go-to option for storing and processing unstructured files, using analytics and integrating extract, transform, and load (ETL) tools.
  • File collaboration and storage: IT can consolidate multiple file servers with NAS storage for ease of management.
  • Archiving: A NAS is suitable for storing many files and creating an accessible and searchable archive.

 

Storage Area Network (SAN)

In other use cases, SAN is the preferred choice:

  • Backups and disaster recovery: Networked devices can be backed up quickly and directly to SAN storage since traffic does not travel over LANs.
  • E-commerce: Consumers expect online shopping to be smooth and quick. A SAN is a good choice for e-commerce companies because they need high-performance functionality.
  • Video editing: Large files require fast throughput and low latency. A SAN can be directly connected to the video editing desktop client, eliminating the need for extra server layers.


NAS vs. SAN in the Cloud: Separate or Combined?

There are several areas where NAS and SAN solutions can benefit from cloud storage.

When using NAS, for example, companies can back up their files automatically from the NAS system to cloud storage using a cloud service provider. A backup from NAS to the cloud is generally charged based on the capacity used and any access fees.

Using a cloud NAS service may require upgrading the network to handle the traffic. High data volumes and heavy traffic may necessitate a costly telecommunications link to the service, which generally incurs significant upfront costs and ongoing expenses.

Suppose you’re using SAN. A virtual SAN leverages the flexibility, scalability, and security of cloud computing for storage and data access throughout an organization. Virtual machines and cloud storage accelerate SAN processing and scalability.

If you are a startup or small to medium-sized business, NAS is probably the better option since it is cheaper and less complicated. But SAN is better if you are a large organization where speed, high throughput, and low latency are essential. 

NAS and SAN are not mutually exclusive. They can be combined and complement each other with cloud storage for an enhanced data storage experience. Combining them into one storage solution could increase scalability and management complexity while lowering costs.
