Best NAS for small business

What matters for a business NAS

A business NAS is judged on uptime and data safety, not benchmarks. It typically holds shared company files, acts as a backup target for staff laptops and servers, and may host a few business apps. The priorities are reliability, redundancy and a backup strategy that survives hardware failure, accidental deletion and ransomware. Synology's business-leaning models earn their place here through ECC memory, mature software and strong backup tooling.

Two features do most of the heavy lifting. Snapshots take frequent point-in-time copies of your data, so if ransomware encrypts files or someone deletes the wrong folder, you roll back to a clean snapshot in moments. Active Backup centralises backups of staff computers, servers and even cloud accounts into the NAS without per-seat licence fees. Together with ECC for integrity and SHR or RAID6 for redundancy, they make a dependable foundation.

The most important principle is that RAID is not a backup. Redundancy keeps you running when a drive fails, but it does nothing against fire, theft, ransomware or human error affecting the whole array. That is why a proper plan layers snapshots on the NAS and a second copy kept off-site.

How much to budget

Budget the appliance and drives as one cost, and remember the drives often equal or exceed the price of the box. For business you should also factor in a second device or service for the off-site copy, because a single NAS, however well protected, is not a complete backup strategy.

Drive choice depends on duty. For heavier, always-on workloads, enterprise drives such as Seagate Exos or WD Ultrastar are built for it and bring strong price per terabyte at capacity. For lighter office use, NAS-rated CMR drives like Seagate IronWolf or WD Red Plus are perfectly adequate. Avoid SMR drives in RAID. Buying drives from the same trusted families keeps support and warranty simple.

Spend where it reduces risk: ECC memory, redundant RAID, snapshots and a genuine second copy. Those protect the business more than a faster processor would, so prioritise reliability features and a sound backup plan over headline performance.
