NAS Storage: Network Attached Storage for Business

NAS storage is a dedicated storage device that sits on your network and shares files with every user and system that needs them. It runs its own operating system and file system, and clients reach it through standard protocols such as SMB for Windows and NFS for Linux. For teams that need one central, protected home for shared files, a NAS is usually the simplest and most economical place to start.

This page covers how NAS works, what to check before you buy, and when a different type of storage makes more sense.

What to look for in NAS storage

Pick the NAS around the way your people and systems will use it. These points narrow the choice quickly.

Form factor and bays. Desktop units suit small offices. Rackmount NAS systems fit a standard cabinet and are common in server rooms, with 1U four-bay and 2U twelve-bay designs among the popular layouts. More bays mean more capacity and more room for RAID.

Number of users. Some business NAS platforms are rated for hundreds of concurrent users, while entry models are built for far fewer. Match the rating to your real headcount, plus growth.

Network speed. A NAS can only deliver as fast as the network allows. Gigabit ports are fine for general office files, but large files and many clients benefit from 10GbE, link aggregation or SFP+ ports. Dual network ports with failover help keep the service up if a link drops.

RAID and protection. Look for RAID 1, 5, 6 and 10 support, hot-swap drives and a choice of redundancy level. RAID 6 and 10 tolerate more drive failures than RAID 5. Snapshots let you roll back from accidental deletion or ransomware, but they are not a backup on their own. Keep a second copy elsewhere, because a fire, theft or total hardware failure takes the snapshots with it.

Protocols and directory support. Confirm support for SMB, NFS and, if you use Macs, Apple file sharing. Active Directory integration lets the NAS use your existing users and groups, which keeps permissions manageable.

Extra features. Many NAS devices also offer iSCSI targets, backup tools, encryption and replication to a second unit. These are useful, but only if you will use them.

Warranty and support. Rackmount NAS systems often ship with longer warranties than desktop models. Check the term and what it covers.

NAS storage products and brands

The business NAS market includes several well-known names. Synology RackStation and QNAP rackmount systems are common for file sharing, virtual machine storage and backup. NETGEAR ReadyNAS rackmount models have offered 2U, twelve-bay designs with snapshots and optional 10GbE. Ubiquiti's UNAS Pro is a 2U seven-bay unit with a 10G SFP+ port. Seagate and Buffalo have also built rackmount NAS units aimed at businesses that want more capacity without adding servers.

Models change often, so check the current listings for what is available now.

Who NAS storage suits

• Shared office files. One central location for documents, projects and department folders, with permissions tied to your directory.
• Backup targets. NAS devices are popular destinations for server and workstation backups, and many include their own backup tools.
• Media and design teams. Large files can be shared across the team instead of copied between machines.
• Smaller virtual environments. A NAS can serve iSCSI volumes or file shares to a modest virtual host setup, though it does not replace a proper server cluster.
• Offloading old data. A lower-cost NAS can hold rarely used data and take pressure off more expensive high-performance storage.

NAS is a weaker fit for busy transactional databases. Those workloads usually do better on block storage with low latency.

NAS, DAS and SAN compared

If only one server needs the capacity, DAS storage is usually cheaper and simpler. If you run transactional databases or large virtual clusters that need low latency, look at SAN storage. If you want a dedicated unit with controllers and RAID that can serve different workloads, compare our storage arrays.

Why buy NAS storage from PonDesk

PonDesk supplies genuine, verified storage hardware sourced through industry channels, so the NAS and drives you specify are what you receive. We aim to price competitively, which matters once you add drives to a multi-bay unit. Free delivery applies on UK orders. For multi-unit or bulk orders, contact us and we can help match hardware to your workload.

What is NAS storage?

NAS storage is a network-connected storage device that serves files to many users and systems. It has its own operating system and file system, and clients connect using protocols such as SMB and NFS. A NAS gives a team one central, shared place for files, backups and media.

What is the difference between NAS and a file server?

A NAS is a dedicated appliance built only for file storage and sharing, while a file server is a general-purpose computer running a file-sharing role. A NAS is usually simpler to set up and manage. A full server is more flexible and can run other applications alongside file sharing.

Is NAS good for business use?

Yes, NAS storage works well for business file sharing, backup and archive. Rackmount models offer hot-swap drives, RAID, Active Directory support and snapshots. NAS is less suited to heavy transactional databases, which usually need the low latency of block storage such as a SAN.

Is a NAS a backup?

No, a NAS is storage, not a backup by itself. RAID protects against drive failure and snapshots protect against accidental changes, but neither covers fire, theft or loss of the whole unit. Keep a second copy of important data on separate hardware or at another site.

How many drives do I need in a NAS?

Most business NAS systems are used with four or more drives. A four-bay unit supports RAID 5 or RAID 10, and eight or more bays give room for RAID 6 and growth. Choose the bay count for your capacity, redundancy level and future expansion.

Ready to choose your NAS storage?

List your user count, file types, network speed and backup plan, then compare the NAS systems that fit. If you need single-server capacity, see DAS storage, or contact us and we will help you size a NAS for your team.
