Can Synology NAS Replace a File Server for CAD Teams?

A missing Revit link, a locked AutoCAD drawing, or a slow file save can stop an entire design team. For firms managing active project folders, the question is not simply where files can be stored. It is whether the storage platform can protect drawing data, maintain access control, and keep users productive during a deadline.

Can Synology NAS replace a file server? For many small and mid-sized CAD, BIM, engineering, and manufacturing teams, yes. A correctly specified Synology NAS can handle shared project files, user permissions, backups, snapshots, and remote-access requirements at a lower management overhead than a traditional Windows file server. It is not a universal replacement, however. The right choice depends on file workflows, team size, network design, application requirements, and the level of IT administration the business needs.

Where a Synology NAS Works Well as a File Server

A network-attached storage device is purpose-built to provide shared storage. Synology NAS systems run DiskStation Manager, which gives organizations a browser-based interface for creating shared folders, managing users, setting permissions, monitoring storage health, and configuring data protection.

For a single-office design team, this can remove much of the complexity associated with maintaining a separate server operating system. Staff can access familiar mapped network drives through SMB file sharing, while administrators can organize access by department, project, client, or role. A structural team, for example, can work in a controlled project folder without granting access to commercial, finance, or unrelated client data.

A Synology NAS is particularly suitable when the core requirement is centralized file storage for documents, PDFs, AutoCAD drawings, reference files, exported models, CAM files, and completed project archives. It can also support Windows Active Directory integration, so organizations already using domain accounts do not necessarily need to recreate users and permissions manually.

The practical advantages are clear:

• Lower initial cost than a dedicated server, operating system licenses, and separate storage hardware

• Simpler day-to-day administration for basic file, user, and backup tasks

• Flexible capacity through multi-bay models and expansion options

• Built-in snapshot, replication, synchronization, and backup tools

• Lower power consumption and a smaller physical footprint than many server configurations

These benefits matter most when an organization needs dependable shared storage without turning file server maintenance into a full-time responsibility.

CAD and BIM Files Need More Than Basic Storage

Design files are not ordinary office documents. AutoCAD drawings often rely on external references, plot styles, fonts, images, blocks, and linked files stored in consistent folder locations. Revit projects can involve large central models, local files, linked models, and intensive read-write activity from multiple users. Manufacturing teams may also work with large assemblies, toolpath data, scans, and revision-controlled production documents.

A NAS can support these workflows, but performance must be designed rather than assumed. The device, drives, switch, cabling, and workstation network adapters all affect the user experience. A fast NAS connected to a 1 GbE network may still become a bottleneck when several users open large models at the same time.

For teams working with larger AutoCAD or Revit files, 10 GbE networking is often worth evaluating. SSD cache can help with frequently accessed data, although it is not a substitute for enough memory, suitable drives, and adequate network bandwidth. Hard disk drives remain cost-effective for high-capacity project storage, while SSD-based volumes may make sense for active files that require faster access.

The physical network also matters. CAD and BIM users should normally work across a stable wired local network, not a weak Wi-Fi connection. Remote work introduces another consideration: opening and saving live project files across a standard internet connection can be slow and unreliable. In many cases, remote desktop access to an office workstation or a properly designed cloud collaboration platform is a better fit than direct file access over a VPN.

Revit Worksharing Requires Careful Validation

Revit worksharing is where businesses should be especially cautious. A local, well-configured NAS using SMB may be appropriate for certain file-based Revit workflows, but it must be tested with the exact Revit version, project size, user count, network environment, and backup process in place. The storage system must deliver consistent availability and file-locking behavior.

For distributed teams, frequent external collaborators, or projects that require cloud-based coordination, Autodesk Construction Cloud and Revit cloud worksharing may be a more suitable approach. A NAS can still serve an important role for local backups, archive storage, exports, and non-cloud project data, but it should not be selected solely because it is less expensive than a collaboration platform.

When a Windows File Server Is Still the Better Choice

A traditional file server remains valuable when file sharing is only one part of a broader server environment. If your organization depends on complex Group Policy management, advanced domain services, specialized database applications, legacy software, detailed auditing requirements, or tightly integrated line-of-business systems, a Windows Server environment may be the better operational choice.

The same applies to organizations with a large number of users, multiple branches requiring sophisticated namespace management, or strict compliance obligations. Synology can integrate with many enterprise environments, but integration is not identical to replacing every Windows Server role.

Businesses should also avoid treating a NAS as an appliance that needs no management. It still requires firmware updates, storage monitoring, permission reviews, backup checks, and periodic capacity planning. A file server that is poorly maintained is risky regardless of whether it runs on Windows hardware or a NAS platform.

The Data Protection Features That Make NAS Attractive

One of the strongest reasons to consider Synology is the opportunity to build practical data protection into the storage design. Snapshots can preserve point-in-time versions of shared folders, helping teams recover from accidental deletion, unwanted overwrites, or some ransomware incidents. Versioned backups can provide a further recovery layer, while replication can copy critical data to another device or location.

However, RAID is not a backup. RAID helps keep data available when a drive fails, but it does not protect against accidental deletion, file corruption, theft, fire, or ransomware that reaches accessible shares. A sensible design follows the principle of maintaining multiple copies of data, on different storage media, with at least one copy kept offsite or isolated from the primary environment.

For active design data, recovery objectives should be discussed before selecting hardware. Ask how much work the business can afford to lose between backups and how quickly a project folder must be restored after an incident. A small office may accept an overnight backup cycle. A busy design department working on deadline-sensitive models may need more frequent snapshots and a tested recovery process.

How to Decide if a Synology NAS Can Replace Your File Server

Start with the workflow, not the product specification. Identify the file types being stored, the largest typical project, the number of concurrent users, and whether staff work primarily in one office or from several locations. Review which applications access the files and whether any vendor has specific requirements for central models, databases, or licensing components.

Next, assess the current network. A NAS will not resolve delays caused by aging switches, congested Wi-Fi, poor cabling, or workstations limited to slow network adapters. For active CAD and BIM teams, storage and networking should be planned as one system.

Permissions deserve the same attention. Build access around real business roles and project responsibilities rather than assigning every user full control. Use separate areas for active projects, issued documents, templates, shared libraries, and archives. This reduces accidental changes and makes handover easier when a project closes or a staff member leaves.

Before migration, copy a representative group of projects to the proposed NAS and test normal work: opening drawings, resolving Xrefs, saving revisions, plotting, working with Revit links, and restoring a deleted file. Do not migrate a live project environment without confirming performance and recovery behavior under realistic conditions.

BLY Technology can help technical teams assess storage, network readiness, CAD and BIM workflows, and the practical support needed after deployment. The goal is not to install more hardware than necessary. It is to build a file environment that supports daily project delivery without creating a new point of failure.

A Synology NAS is often a sensible file server replacement when shared storage is the main need and the environment is properly sized, secured, and backed up. Where workflows are more complex, it may be better viewed as part of a wider server and collaboration strategy. The best decision is the one that lets your team find, open, save, protect, and recover project information without slowing down the work that earns the business revenue.
