Synology DS220+ Review in 2026: Keep It, Upgrade It, or Buy Used?

The lifecycle signal is mixed, not alarming

DS220+ is Discontinued, yet Synology currently shows Full DSM updates. Technical support is Limited, which changes the risk posture more than the software path. Home owners can continue using a stable unit with strong backups; organizations that depend on rapid vendor assistance may place more weight on that limited-support label. Those are different decisions even when the hardware is identical.

For a NAS that mainly protects laptops and phones, the most useful health test is not a benchmark. It is whether scheduled backups still finish inside the expected window, restores can be performed, and DSM remains responsive while jobs run. If those three conditions hold, the DS220+ can continue delivering value even when newer hardware is dramatically faster on paper.

J4025 is enough for the jobs this NAS was built for

The dual-core Intel Celeron J4025 and 2 GB of DDR4 are modest resources, with an official memory maximum of 6 GB. File sharing, Time Machine, PC backups, Synology Photos and light media serving fit naturally. A growing stack of databases, indexers and AI-heavy photo services does not. Keeping workloads aligned with the hardware is the simplest way to extend useful life.

DSM 7.4 preserves modern management features

DS220+ remains on the current DSM 7.4 path used for this Sprint. That keeps security and platform maintenance relevant, but an upgrade should still be prepared. Verify a restorable backup, record package versions and check any third-party applications. DSM 7.4 is not something to install casually if the NAS contains the only working copy of important data.

Two gigabit ports are adequate until they are not

For nightly backups and household file access, a single gigabit link can already be enough. The second port adds resilience and aggregate options, but this is not a multi-gig chassis. Users editing large media directly from the NAS or moving multi-terabyte datasets will feel the ceiling. If those transfers are rare, faster Ethernet may have little effect on day-to-day satisfaction.

Intel media capability gives it a useful home-server role

The J4025 includes integrated graphics, making DS220+ more interesting for certain Plex and Jellyfin tasks than its basic CPU score implies. A small media household can continue to get value from hardware-assisted conversion when supported. The two-bay capacity ceiling may arrive before media processing does, especially as high-bitrate libraries grow. Storage forecasting and playback testing should therefore be done together.

A few containers are different from a homelab

DS220+ can run lightweight services, but its memory ceiling makes discipline important. DNS, a small utility and one or two supporting applications are reasonable; a sprawling self-hosting portfolio can make DSM feel crowded. If containers are multiplying, a small separate compute node can preserve DS220+ as storage. That split often costs less than replacing healthy drives and a working NAS just to gain CPU.

No M.2 and no bay expansion keep the design simple

There are no internal M.2 slots and no supported DX expansion path. The architecture is therefore easy to understand: two main bays, larger replacement disks when necessary, and eventually migration to a larger chassis. This can be a virtue for users who want an appliance rather than a project, but it also means there is little point buying DS220+ today if you already know two drives will not be enough.

Capacity upgrades replace both sides of the mirror

A two-bay SHR or RAID 1 pool commonly requires both disks to be upgraded before the full larger capacity becomes useful. That makes repeated growth steps expensive compared with adding a drive to a larger array. Estimate your photo, backup and media growth for several years. If the next disk pair already looks oversized or costly, moving to four bays can create a more flexible capacity curve.

Quiet NAS drives suit the enclosure well

A DS220+ is often close to people, so low vibration and reasonable acoustic behavior matter. NAS-rated CMR disks sized with generous headroom are usually a better household fit than chasing the cheapest enterprise capacity at any noise level. Whatever drive is selected, RAID does not replace an external or cloud backup, particularly on an aging two-bay chassis.

Capacity planning should also include the size of the backup copy. Moving from two 8 TB disks to two 20 TB disks can solve local space pressure while quietly creating a much larger off-site protection requirement. Price the complete protection plan, not only the disks inside the NAS, before deciding whether an in-place capacity jump is cheaper than moving to more bays.

Limited support increases the value of self-preparation

Keep a configuration record, note the drive order, maintain a tested backup and know how you would restore onto another Synology if the enclosure fails. Those habits matter more as the product moves deeper into its lifecycle. They also reduce upgrade anxiety because the data is portable by process rather than by hope. A NAS should never become irreplaceable simply because it has been reliable for years.

Used DS220+ should be cheap and boring

There is little reason to pay collector pricing for DS220+. A good used unit should be clean, stable, fully reset and inexpensive enough that the limited support state and two-bay ceiling are already reflected in the price. Check both Ethernet ports and listen for fan or power issues. If the price approaches DS225+, the new model’s warranty and 2.5GbE option become difficult to ignore.

The natural upgrade is about scale

DS225+ is a straightforward path when two bays remain enough but faster networking matters. DS725+ makes more sense when memory and expansion are becoming priorities. A four-bay model is the better leap when storage growth is the real problem. Choosing among them is easier once you name the constraint rather than asking for a generic “successor” to DS220+.
