A picture of a professional holding their phone and a connected device as this article is about the best network attached storage devices also known as NAS hardware and software solutions. This article looks at the top enterprise-grade NAS solutions for small businesses up to enterprise organization storage needs.

Network-attached storage (NAS) hardware and software solutions can ease and enhance the task of managing data for individuals up to enterprise data centers.

NAS appliances offer organizations secure storage and file access to groups of users at a lower cost relative to the latest file servers. Both file servers and NAS perform similar functions, but most organizations don’t need the extent of features included in general-purpose servers. Today’s NAS solutions optimize local storage, public cloud data migration, and private cloud management.

This article looks at the top vendors, products, and solutions for NAS appliances, as well as their features, pros, and cons.

What Is Network-Attached Storage?

Network-attached storage is hardware appliances or virtual machines dedicated to storing data specific to a home, business, data center, or enterprise network. After the success of file servers in the 1980s, NAS devices grew as an alternative to dedicated file servers, offering central storage and access to a group of users.

Today, NAS appliances continue to be a popular addition for home or enterprise networks needing to securely store and share data, including creating a private cloud.

How NAS Hardware Impacts Performance

Hardware makes a difference for business and enterprise NAS needs. Like the above top vendors, NAS manufacturer and model specifications mean clients need to pay attention to variations in:

  • Support for drives (HDDs and SDDs)
  • Number of bays for disk drives
  • USB and other connector ports
  • Pre-populated or diskless RAID configuration
  • Processing and storage capacity
  • Embedded operating system features

What Is NAS Software?

NAS software is the programs and systems designed to run network-attached storage devices. Most enterprise vendors offer their proprietary operating system embedded in hardware, while there’s also an abundance of free and open-source NAS software solutions.

Administrators can centrally manage storage devices with NAS software to maintain security, migrate specific data, and optimize data storage.

NAS Software Features

  • Backups: Regular synchronizations for recovering a complete copy of data
  • Snapshots: Active digital pictures of data for point-in-time recovery
  • Replication: Replicate and pull the most recent snapshots when offline
  • Encryption: Full-disk encryption and self-encrypting drives for security
  • Connectors and Controllers: Manage integrations and port connections
  • Administrative Management: Central console and controller for NAS data

Storage Area Network (SAN) vs NAS

As a single physical device, a NAS appliance has long been a cost-effective way to deploy and maintain data for a group of users. With the evolution of networking and the boom in client devices for geographically distributed networks, the storage area network (SAN) emerged to meet data management needs for enterprise IT environments.

How to Choose a NAS Software Solution

There’s no shortage of models, features, and software to consider, so start the journey today by checking out the above vendors’ portfolios for small business and enterprise clients.

Product features to keep in mind when evaluating these options include:

  • Storage and memory capacity and scalability
  • Security, protection, and encryption
  • Speed, latency, and performance
  • Cloud integrations and remote access
  • Pre-configured models vs flexibility to add and alter components

With plenty of specs to consider and the steep cost of some models, data administrators must be familiar with organization needs and existing infrastructure to avoid an expensive mistake. Hardware warranties, application integrations, and scaling opportunities are all worth confirming before moving forward with a purchase.
