Review: Synology DiskStation DS1825+ Network-Attached Storage

To see whether it lives up to that promise, I deployed the DS1825+ as the primary file and backup server for a 10-person office over a full month. I populated it with eight enterprise hard drives in a redundant configuration, connected it to the network, pointed every workstation’s backups at it and ran two virtual machines (VMs) and a small surveillance deployment on top for additional stress testing.

Eight staff members used the system during my month-long evaluation, providing additional observations on transfer speeds, reliability and ease of access. 

Setup deserves special mention, because this is where many storage projects either succeed or fail. During my evaluation, I went from unboxing the DS1825+ to a fully configured storage volume in less than an hour. The tool-less drive trays simplified installation, while Synology’s DiskStation Manager guided the remainder of the configuration through an intuitive browser-based setup process. For smaller organizations without dedicated storage specialists, such ease of deployment could significantly reduce implementation time.

What Separates the DS1825+ From Rivals

In my evaluation, four qualities lifted the DS1825+ above many other storage systems I have tested. 

First, size and capacity: Eight hot-swappable bays hold up to 360 terabytes of raw storage today, and two optional DX525 expansion units push that to 18 drives and as much as 432TB with the latest high-capacity disks for future storage needs. Synology Hybrid RAID makes it easy to balance redundancy and space, and because drives are hot-swappable, I replaced a disk during the workday without taking the office offline.

Active Backup for Business pulled full images of every PC and VM on a schedule, with no per-seat licensing to balloon the budget. Hyper Backup pushed an encrypted copy offsite to round out a proper 3-2-1 backup strategy, and immutable snapshots provided a ransomware safety net that a simple file copy never could.

Two built-in 2.5-gigabit ports, with link aggregation and SMB multichannel, eliminated the bottleneck that throttled my old storage server; a PCIe expansion slot allows me to scale to 10- or 25-gigabit networking later, if needed.

Synology’s DiskStation Manager is intuitive and well-built. I configured storage, scheduled backups, spun up VMs, managed a handful of security cameras through Surveillance Station and enabled multifactor authentication and encryption, all from one browser tab. It looks and behaves like a real operating system, meaning even a nonspecialist administrator could manage the deployment successfully.

Three Storage Challenges Every Growing Business Eventually Faces

Most growing businesses do not think much about storage until something goes wrong. Whether it’s soaring cloud costs, ransomware or employees waiting on large files to transfer, data management problems tend to appear gradually before suddenly becoming urgent.

Here are three storage challenges small and midsize organizations face most often and how a system like the Synology DS1825+ can help address them.

1. Runaway Data Growth and Cloud Bills

Many growing businesses generate more data every quarter than they once did over an entire year. Richer media, longer retention requirements and new AI tools all contribute to that growth.

A network-attached storage device like the DS1825+ gives organizations a way to regain control and grow their storage footprint without relying exclusively on recurring cloud costs. Files remain on the local network where they are fast to reach, while built-in tools can still sync copies to the cloud when offsite redundancy is required. The result is room to grow without a monthly bill that grows just as quickly.

2. Ransomware and the Backup Gap

Many small businesses believe they are protected because files are copied somewhere, only to discover during an incident that the backup was incomplete, out of date or encrypted right along with the originals. Ransomware in particular preys on that gap, and downtime from a failed recovery can be existential for a smaller company.

The DS1825+ addresses the problem with layered, license-free protection. Active Backup for Business captures whole machines on a schedule, Hyper Backup ships an encrypted copy offsite to satisfy the 3-2-1 backup rule, and immutable snapshots create restore points that ransomware cannot alter.

In testing, restoring a deleted folder or an entire workstation took minutes, turning what could have been a worst-case scenario into a routine recovery task.

3. Performance Bottlenecks in Multiuser Workflows

Performance problems often emerge when multiple employees access large files simultaneously. Creative teams, engineers and finance departments can quickly overwhelm storage systems originally designed for just a handful of users.

With dual 2.5-gigabit networking, link aggregation, optional NVMe caching and a clear path to 10- or 25-gigabit speeds, the DS1825+ keeps multiple users moving large files at once without the slowdowns that plagued older NAS devices.

For growing businesses, that performance headroom matters. Shared storage should help teams work faster, not become another bottleneck they have to work around.

SMBs almost certainly rely on shared storage and reliable backups to keep their operations moving and their auditors happy. The DS1825+ delivers, with depth of features that punch well above its modest footprint and price. It made my data faster to reach, far harder to lose and dramatically easier to manage.
