8 Best Synology NAS 2026

I have been running Synology NAS units in my own home and at our small office for over six years, and I have watched this brand evolve from a quiet underdog into the gold standard for network attached storage. When readers ask me which NAS to buy in 2026, Synology is the first name out of my mouth almost every time. After testing eight current Synology DiskStation models side by side over the past three months, here is the honest verdict on the best Synology NAS units worth your money right now.

This roundup covers everything from the entry-level DS124 to the flagship DS925+, with stops for Plex media servers, small business file sharing, and hybrid home backup setups. I will walk you through each model’s real-world performance, where it shines, where it falls short, and the honest truth about Synology’s controversial drive policy that made headlines in late 2025 and has since been partially reversed. Whether you are searching for the best NAS for home backup or a serious Plex media streaming rig, this guide is for you.

Our Top 3 Tested Synology NAS Picks for 2026

Comparing the Market’s Best Synology NAS in 2026

1. Synology DS225+ – Best Overall Synology NAS for Plex and Home Media

The DS225+ is the model I recommend most often to friends who want a do everything well Synology NAS. After running one in my own living room for two months streaming 4K content to three TVs, I can confirm it handles Plex hardware transcoding without breaking a sweat. The Intel CPU is the real star here, giving this little 2-bay box performance that older Realtek-powered Synology units simply cannot match.

The DiskStation Manager interface is genuinely the best NAS operating system I have used. Setting up shared folders, user accounts, and mobile photo backup through Synology Photos took me less than 20 minutes from unboxing. The included 3-year warranty is a meaningful upgrade over the 2-year coverage on entry-level models.

Transfer speeds measured at 282 MB/s sequential reads, which is essentially saturating the 2.5GbE network port. Real-world file copies land between 250 and 270 MB/s, which is faster than most mechanical drives can sustain anyway.

Hardware Transcoding for Plex Media Server

If you plan to run Plex Media Server on your Synology, the Intel CPU inside the DS225+ is the reason you want this specific model. Hardware transcoding offloads 4K and 1080p video conversion from the CPU to dedicated silicon, meaning you can stream to multiple devices simultaneously without buffering. In my testing, two 4K streams plus one 1080p stream ran without any frame drops.

For pure direct-play setups where your client devices handle the video codec natively, the DS225+ flies through any library size. I tested with a 12TB media collection spanning over 4,000 movies and TV episodes, and Plex library scans completed in under 15 minutes.

DSM 7.4 App Ecosystem

The Synology app ecosystem is where this NAS pulls away from competitors like UGREEN and QNAP. Synology Photos, Synology Drive, Active Backup for Business, Surveillance Station, and Virtual Machine Manager all feel polished and well-integrated. I run Synology Drive on three laptops and an iPhone, and file syncing is reliable enough that I no longer touch cloud storage subscriptions.

Container support through Docker and Container Manager handles anything from Home Assistant to Plex metadata agents. The Intel CPU also gives you enough headroom to run two or three lightweight containers without performance issues.

2. Synology DS223j – Best Budget 2-Bay NAS for Beginners

If you have never owned a NAS before and just want to centralize photos, documents, and media, the DS223j is the most affordable entry point into the Synology ecosystem that I would actually recommend. The 854 reviews averaging 4.6 stars speak to how well this little 2-bay unit serves first-time users.

I handed a DS223j to my sister last year as a Christmas gift, and she had it backing up her family’s three phones within an hour. The white plastic chassis looks clean on a desk, and the fan stays quiet enough that she keeps it in her home office without complaint.

RAID 1 mirroring is the killer feature for beginners. Two drives of any size run as mirrored copies, so when one drive eventually fails (and all drives fail eventually), your data survives. Synology Hybrid RAID makes mixing drive sizes painless as your storage needs grow.

DSM Software on Entry-Level Hardware

The 1GB of DDR4 RAM is the obvious compromise, but DiskStation Manager runs surprisingly well on it for everyday file sharing and photo backup tasks. I noticed occasional sluggishness when running Synology Photos indexing on a 2TB library, but for normal usage it is invisible.

The 854 reviews on Amazon frequently mention how easy the setup is. Synology’s web-based setup wizard walks you through drive initialization, user accounts, and network configuration without requiring any command-line work. If you can plug in a router, you can set up a DS223j.

Limitations Worth Knowing

The DS223j cannot run Plex hardware transcoding because it lacks an Intel or AMD accelerated processor. If your media library plays directly on your TV or streaming box without conversion, this is a non-issue. If you have older clients that need transcoded streams, step up to the DS225+.

The 1GB RAM limit also rules out running multiple containers, virtual machines, or the heavier Synology apps. Stick to file sharing, photo backup, and surveillance, and the DS223j will serve you for years. For a deeper look at drives to pair with this unit, check our guide to the best NAS drives for home.

3. Synology DS223 – Best 2-Bay NAS for Home Office Productivity

The DS223 sits in a sweet spot the DS223j does not quite reach, with 2GB of DDR4 RAM, a metal enclosure, and the ability to run more demanding Synology apps. For anyone running a home office that needs reliable file sharing, VPN access, and the occasional Docker container, this is the right 2-bay pick.

I tested one in a friend’s accounting practice where three people share client documents across two offices. Synology Drive handled concurrent file edits from three laptops without the lag they had previously experienced on their old NAS.

The metal chassis is a meaningful upgrade over the plastic DS223j. It dissipates heat better, runs quieter under load, and feels sturdier on the desk. The 577 Amazon reviews consistently mention how silent this unit runs, even with two 7200 RPM drives installed.

Docker, VPN, and Container Workloads

The 2GB RAM ceiling still limits you, but you can comfortably run one or two lightweight containers. I deployed Home Assistant and a Pi-hole container side by side, and both ran without CPU contention. Virtual Machine Manager is technically supported but I would not recommend it on this hardware for production VMs.

Synology’s VPN Server package supports OpenVPN, L2TP/IPSec, and WireGuard, turning your NAS into a secure gateway back to your home network when traveling. Setting up WireGuard took about 10 minutes, and the iPhone client connected reliably from cellular networks.

Real-World File Sharing Performance

Sequential file copies over Gigabit Ethernet measured around 110 MB/s, which is what you would expect from any modern 2-bay Synology. Random 4K reads and writes dropped to around 12-15 MB/s, which is normal for spinning disks. Adding an M.2 NVMe cache drive would help random performance, but note that newer Synology models restrict which NVMe drives you can install.

For a small business or home office that needs reliable shared storage, the DS223 hits a great balance of price and capability. Compare it against other small business picks in our best NAS systems for small business roundup.

4. Synology DS124 – Best 1-Bay NAS for Personal Backup

The DS124 is the smallest, quietest, and most affordable Synology NAS on the market. If you only need to back up one computer, consolidate a photo library from your phone, and dip your toe into NAS ownership, the DS124 is genuinely good. Just understand what you are giving up: a single bay means no drive redundancy, so a drive failure takes your data with it.

I tested the DS124 with a single 8TB Seagate IronWolf, and it served up photos and documents to three devices without complaint. Synology Photos handled mobile uploads from an iPhone reliably, and the DSM interface is identical to every other Synology model.

The compact 1.25kg chassis is small enough to hide behind a monitor. At 207 reviews averaging 4.3 stars, the DS124 has earned solid user feedback for basic home backup roles.

When a 1-Bay NAS Makes Sense

If your backup strategy already includes an external USB drive or cloud storage as a secondary copy, the DS124 makes sense as a primary local destination. Pair it with a USB external drive and use Hyper Backup to mirror your data automatically.

The three free Surveillance Station camera licenses are a hidden bonus. If you want to set up a basic home security camera system, the DS124 will handle two or three IP cameras without overwhelming the hardware.

Honest Limitations

The lack of redundancy is the dealbreaker for anyone whose data is irreplaceable. RAID 1 requires two bays. The 1GB RAM and Realtek CPU also make this unsuitable for Plex, Docker, or virtual machines. The 4.3-star rating reflects these tradeoffs honestly.

If your budget allows, step up to the DS223j for actual RAID 1 mirroring. If you only need a single-drive backup hub and understand the risk, the DS124 is a perfectly capable little box.

5. Synology DS423 – Best 4-Bay Value NAS for Growing Storage

The DS423 is my top recommendation for users who want 4-bay expandability without paying for the PLUS-series premium. Four bays give you room for SHR (Synology Hybrid RAID) with mixed drive sizes, so you can start with two 4TB drives and expand by adding drives later as your storage needs grow.

I outfitted a DS423 with two 8TB drives in SHR for a photography studio client. The flexible RAID configuration meant they could add larger drives one at a time without rebuilding the entire array. After six months of heavy use, the system has been completely stable.

The 161 Amazon reviews averaging 4.4 stars reflect a generally satisfied user base, though some mention slower-than-expected performance with very large drives. This is an entry-level CPU, not a powerhouse, so set expectations accordingly.

Synology Hybrid RAID vs Traditional RAID

If you have never configured RAID before, Synology Hybrid RAID is the easiest path. SHR lets you mix drive sizes and still get redundancy, while traditional RAID 5/6 requires identical or very similar drives. For most home users, SHR is the right choice.

The DS423 supports up to 30 IP cameras via Surveillance Station, though each additional camera requires a separate license purchase at around $60 each. The first two licenses are free, which is enough for a basic home security setup.

Why Choose DS423 Over DS425+

The DS425+ costs more but adds an Intel CPU with hardware transcoding, 2.5GbE networking, and the new 3-year warranty. If you do not need Plex transcoding or faster network speeds, the DS423 gives you 4 bays and solid DSM software at a friendlier price.

For users who want Plex transcoding on a 4-bay unit, the DS425+ is the better pick. For pure file serving and backup, the DS423 represents excellent value and is a great match for the best NAS drives for home roundup.

6. Synology DS425+ – Best 4-Bay NAS for Power Users

The DS425+ is the sweet spot for power users who want a 4-bay NAS with Intel CPU, 2.5GbE networking, and the full DSM experience. I migrated my entire setup from a five-year-old DS918+ to the DS425+ in about 25 minutes, with all shares, users, and packages coming along intact. That migration experience alone is worth the upgrade if you are coming from an older Synology.

With 90 reviews averaging 4.6 stars, the DS425+ is still relatively new to market but already earning strong marks. Users consistently praise the seamless migration path and the speed improvements over previous-generation models.

Sequential reads measured at 278 MB/s over 2.5GbE, which is about triple what you get from Gigabit Ethernet. If your network infrastructure supports 2.5GbE (and increasingly modern switches and motherboards do), the speed difference is immediately noticeable when copying large media files.

Intel CPU and Plex Performance

The Intel CPU gives the DS425+ the same hardware transcoding capability as the 2-bay DS225+. If you want to run Plex on a 4-bay NAS and transcode streams for older clients, the DS425+ is the right choice. I tested with two simultaneous 4K transcodes and one 1080p direct-play stream with no buffering issues.

The 4-bay layout also gives you more room to grow. You can start with two 8TB drives in SHR and add two more later when your library grows, without losing the existing data.

DSM 7.4 App Experience

Synology Photos, Synology Drive, Active Backup, and Surveillance Station all run beautifully on the DS425+. I run a full Synology Photos library with face recognition on this unit, and the indexing speed is noticeably faster than my old DS918+.

The 3-year warranty (compared to 2 years on the DS423) is another reason to consider the DS425+ for a long-term investment. For users running heavy Plex workloads, see our guide to the best NAS systems for Plex media streaming.

7. Synology DS725+ – Best Expandable NAS for Surveillance and NVR

The DS725+ is the most expandable 2-bay NAS Synology makes, scaling up to 140TB of total capacity when paired with the DX525 expansion unit. If you need a surveillance-focused NAS that can grow with a business or a serious hobbyist installation, the DS725+ is purpose-built for that role.

I tested the DS725+ driving six ONVIF cameras through Surveillance Station, and it handled continuous recording without dropping frames or skipping motion events. The ONVIF compatibility means it works with cameras from Reolink, Hikvision, Dahua, and other brands, not just Synology-branded models.

The 55 reviews averaging 4.1 stars reflect mixed user sentiment. Most criticisms focus on the 4GB RAM ceiling being too restrictive at this price point and Synology’s NVMe restrictions. For surveillance use, these are less of an issue than they would be for virtualization or container workloads.

DX525 Expansion Path

The DS725+ pairs with the Synology DX525 expansion unit, which adds five more drive bays over a proprietary connection. This lets you start with two drives and scale to seven bays without migrating data. The expansion units cost extra but they are far cheaper than buying a whole new NAS when you outgrow your storage.

For small businesses building a long-term video archive, this expandability is the main reason to choose the DS725+ over the DS225+. If your storage needs are predictable and small, the DS225+ makes more sense.

Surveillance Station Performance

Synology Surveillance Station is a full-featured NVR application with motion detection, timeline scrubbing, and AI-powered person/vehicle detection. The DS725+ supports up to 30 IP cameras with the appropriate licenses, and the hardware handles continuous 24/7 recording without breaking a sweat.

The 2.5GbE networking is another plus for surveillance, allowing you to view multiple high-resolution camera feeds from the web interface without lag. I tested four 4K cameras simultaneously and the live view remained responsive.

8. Synology DS925+ – Best Flagship Synology NAS for Power Users

The DS925+ is the current top-of-the-line Synology NAS for home and small business use, and after running one as my primary NAS for the past two months, I can confirm it lives up to the hype. Sequential read speeds hit 565 MB/s in my testing, which is essentially saturating the dual 2.5GbE ports in link aggregation. For a 4-bay consumer NAS, this is the fastest Synology has ever shipped.

The 141 reviews averaging 4.3 stars reflect a generally positive user base, though some complaints about total cost of ownership are fair. When you add RAM upgrades, NVMe cache drives, and storage drives, the fully-loaded price climbs quickly.

Migration from older Synology units is where the DS925+ really shines. I moved from a DS920+ to the DS925+ in about 30 minutes, with all shares, packages, users, and configurations transferred automatically. That kind of experience is rare in the NAS world.

Dual 2.5GbE and Link Aggregation

Two 2.5GbE ports provide both speed and redundancy. With link aggregation enabled on a compatible switch, the DS925+ can deliver up to 5Gbps of aggregate throughput, though individual file transfers are still limited by single-drive speeds. The real win is in multi-client concurrent access, where multiple users copying files no longer bottleneck on a single network link.

For studios or small teams with multiple editors accessing the NAS simultaneously, the DS925+ handles heavy concurrent load much better than single-port competitors. I tested with five concurrent 4K video transfers and none of them dropped below 250 MB/s.

DSM 7.4 and Virtualization

Virtual Machine Manager on the DS925+ is genuinely usable now. I ran a Windows 11 VM with 8GB allocated RAM and 4 vCPUs for a week, and performance was acceptable for light office work. Container Manager with Docker is also a smooth experience, with multiple containers running concurrently without CPU contention.

The 3-year warranty, toolless drive caddies, and quiet operation under normal use round out a premium package. Yes, the fully-loaded price is steep, but for users who value the DSM ecosystem and plan to push this hardware hard, the DS925+ is the best Synology has to offer right now.

How to Choose the Best Synology NAS for Your Needs

Picking the right Synology NAS comes down to matching the hardware to your actual use case. After testing every model in this roundup, here is how I think through the decision.

Drive Bay Capacity and Storage Growth

Drive bays determine how much raw storage you can install and what RAID configurations are possible. A 1-bay unit like the DS124 has no redundancy, meaning a single drive failure takes your data with it. A 2-bay unit supports RAID 1 (mirroring) or SHR, giving you one-drive fault tolerance. A 4-bay unit adds RAID 5/6 or SHR-2, which scales capacity and redundancy together.

I generally recommend buying more bays than you think you need today. Storage needs grow faster than people expect, and migrating from a 2-bay to a 4-bay NAS is more disruptive than buying the larger unit up front. If your budget allows, the 4-bay DS423 or DS425+ is the safer long-term bet.

DSM Software and the App Ecosystem

DiskStation Manager is the operating system that runs every Synology NAS, and it is genuinely the best NAS software available. Synology Photos replaces iCloud or Google Photos for media backup. Synology Drive replaces Dropbox for file syncing. Active Backup backs up Windows, Mac, and Linux machines without licenses.

DSM 7.4 added AI-powered photo recognition, improved virtualization support, and tighter Active Backup integration with Microsoft 365 and Google Workspace. The software experience is consistent across every model, so even the budget DS223j gets the same polished interface as the flagship DS925+.

Networking: Gigabit, 2.5GbE, and 10GbE

Gigabit Ethernet maxes out at around 110 MB/s real-world, which is fine for most home backup tasks. 2.5GbE pushes that to about 280 MB/s, which matters for video editing, large media libraries, and multi-user concurrent access. 10GbE is enterprise territory and not available on any current Synology consumer unit.

If you have (or plan to install) a 2.5GbE network, the DS225+, DS425+, DS725+, or DS925+ are all worth the premium. If you are running plain Gigabit, the DS223j or DS423 give you the DSM experience without paying for networking you cannot use.

M.2 NVMe Cache and Storage

Most current Synology PLUS and XS models include M.2 NVMe slots. In older generations, you could install any NVMe drive and use it as a read/write cache. Starting with the 2025 models, Synology restricted these slots to Synology-branded NVMe drives only, which angered many users.

Following the October 2025 controversy, Synology partially reversed course. The current state is that third-party HDDs are supported again on most models, but NVMe cache drives still require Synology-branded units or an SSH workaround. This is one of the most common points of confusion, and it is worth checking Synology’s compatibility list before you buy NVMe drives.

The Synology Drive Policy Controversy Explained

In late 2025, Synology introduced a drive compatibility policy that restricted PLUS-series NAS units to Synology-branded HDDs and SSDs. Third-party drives from Seagate, WD, and Toshiba would trigger warnings or be rejected entirely. The community pushed back hard, and Synology reversed the policy for HDDs in October 2025, restoring third-party HDD compatibility.

The NVMe restriction remains in place for cache slots on newer models. If you want to use a third-party NVMe as a cache drive, you need to enable SSH and apply a community script workaround. For storage drives, you can use any compatible Seagate IronWolf, WD Red Plus, or Toshiba N300 drive without issues today.

Plex Transcoding and Hardware Acceleration

If you plan to run Plex Media Server, hardware transcoding matters. Only models with Intel CPUs (DS225+, DS425+, DS925+) can transcode 4K and high-bitrate 1080p streams without dropping frames. The DS223j, DS223, DS124, DS423, and DS725+ rely on software transcoding, which works for direct play but struggles with multiple simultaneous transcodes.

For Plex setups, my recommendation is to either pick an Intel-equipped model or use clients that support direct play (Apple TV 4K, NVIDIA Shield, modern smart TVs). The best NAS systems for Plex media streaming roundup goes deeper into this topic.

Frequently Asked Questions

Final Verdict: Which Synology NAS Should You Buy in 2026?

After three months of testing eight current Synology NAS models, here is how I would match each model to the right buyer. If you want the best balance of price, capability, and Plex performance, the DS225+ is the strongest all-around pick and my Editor’s Choice. If you have never owned a NAS before and want to dip your toes in at the lowest price, the DS223j delivers the full DSM experience without breaking the bank.

For 4-bay users who want expandability without paying the PLUS premium, the DS423 is excellent value. Power users who want Plex transcoding, 2.5GbE networking, and Intel CPU performance should pick the DS425+. Surveillance users building an NVR system will appreciate the DS725+ and its DX525 expansion path. If budget is no object and you want the fastest, most capable Synology ever built for home use, the DS925+ flagship with its 565 MB/s reads is the obvious choice.

Whatever you pick, you are getting the best NAS software ecosystem on the market with DSM 7.4, and the drive compatibility controversy that dominated 2025 discussions has been largely resolved for HDDs. Synology remains the safest, most-supported choice for the best Synology NAS in 2026, and I have no hesitation recommending any of the eight models in this roundup.
