Synology vs QNAP in 2026: Which NAS Brand to Buy?

Synology is our pick for software-first buyers in 2026, and QNAP is our pick when the NAS doubles as a home-lab server. DSM, Active Backup for Business, and Synology Drive form the more integrated software stack. QNAP answers with more hardware for similar money: Intel Quick Sync for Plex, more base memory, and a PCIe slot.

Buy a Synology DS925+ if the NAS is mainly for storage, backup, and file sync. Buy a QNAP TS-464 if you need Plex hardware transcoding, a PCIe expansion slot, or more room for containers. The two are similarly priced, so compare current prices on both before deciding.

Software Ecosystem: DSM vs QTS

DSM 7.4 is our preferred NAS operating system for ease of administration. Its first-party apps work together with little setup.

Active Backup for Business backs up Windows PCs, Macs, physical servers, file servers, and virtual machines to the NAS from one console, and Active Backup for Microsoft 365 covers cloud accounts. QNAP covers similar ground with separate tools: Hybrid Backup Sync (HBS 3) for NAS-to-cloud and NAS-to-NAS jobs, and NetBak PC Agent, which gained full Windows system backup with QTS 5.2. Synology’s suite is the more integrated of the two.

Synology Drive is a mature self-hosted alternative to Dropbox, with sync, versioning, and sharing. QNAP’s equivalent, Qsync, covers the same basics; we think Synology Drive is the more refined of the two.

DSM 7.3 added Synology Tiering for moving rarely used data to cheaper storage, custom data masking in the AI Console before data reaches third-party AI services, and enhanced file locking in Synology Drive. QTS 5.2 added Security Center, which watches for unusual file activity and can respond with protective measures such as backups or blocking, plus a kernel-mode SMB daemon that QNAP says helps most on all-flash storage.

Both platforms have mature app catalogs. DSM’s first-party apps are more consistent, while QTS offers more hardware-level options, such as HDMI output and more container types. If you live inside the NAS’s native apps, Synology wins.

Winner: Synology. DSM is the easier OS to administer, and Active Backup is its strongest single feature.

Hardware Value per Dollar

This is where QNAP fights back.

The QNAP TS-464 ships with an Intel Celeron N5095 (four cores, up to 2.9 GHz) with Intel UHD Graphics, 8 GB of DDR4, dual 2.5GbE, two M.2 NVMe slots, a PCIe Gen 3 x2 slot, and HDMI 2.1 output. The Synology DS925+ has an AMD Ryzen V1500B (four cores, eight threads), 4 GB of ECC DDR4, dual 2.5GbE, and two M.2 NVMe slots, with no PCIe slot and no HDMI.

At similar prices, QNAP delivers more hardware. Synology’s case rests on software and ECC memory. Both are legitimate, but not every buyer needs them.

In two bays, Synology’s current DS225+ pairs an Intel Celeron J4125 with one 2.5GbE port, one 1GbE port, and DSM, but has no M.2 slots. QNAP’s TS-264 has an Intel N5095, 8 GB of memory, dual 2.5GbE, two M.2 slots, and a PCIe Gen 3 x2 slot. QNAP’s ARM-based TS-233 is a basic two-bay for file and photo backup. If you see the previous-generation DS224+, compare it with the DS225+ on capability and lifecycle, not remaining-stock price.

If you need 10GbE on Synology, the five-bay DS1525+ keeps the V1500B and adds a network upgrade slot for Synology’s E10G22-T1-Mini module.

Winner: QNAP. More memory, more ports, and a PCIe slot at similar prices. Synology’s software premium is worth paying for some buyers, not all.

Docker and Container Support

Both brands run Docker containers capably, but the tools differ.

Synology’s Container Manager, the successor to its Docker package, integrates tightly with DSM and gives you a clean web UI for pulling images and managing containers and networks. Common self-hosted apps such as Home Assistant, Pi-hole, Vaultwarden, and Immich publish x86-64 images that run on either brand. The DS925+‘s V1500B has eight threads and takes up to 32 GB of ECC memory, which leaves real headroom for a container-heavy build once you add RAM.

QNAP’s Container Station is more feature-rich. It runs Docker, LXD, and Kata containers and exposes more networking options in its web UI. The TS-464’s N5095 has four threads, half the DS925+‘s eight, but a higher peak clock (2.9 GHz versus 2.2 GHz) and twice the base memory. Upgrade to 16 GB for heavier use.

If containers become the main job, a dedicated Docker NAS or a mini PC running Proxmox is a better home for them than either appliance. For a typical home lab running a modest set of containers alongside file storage and backup, both brands handle it.

ECC memory matters for always-on workloads. A bit flip in a database container’s memory can corrupt data silently, and Synology’s ECC support provides a real, if small, safety margin that these QNAP models lack.

Winner: Draw. Container Station has more features; Container Manager has better DSM integration. ECC tips the scale slightly toward Synology for always-on workloads.

Plex Transcoding

This is QNAP’s clearest win.

The TS-464’s Intel N5095 includes Intel UHD Graphics with Quick Sync, the hardware video engine that Plex uses for hardware-accelerated transcoding. Plex requires a Plex Pass for hardware transcoding, and its NAS notes say a Jasper Lake or newer CPU is needed to transcode reliably to HEVC. The N5095 is a Jasper Lake chip.

The DS925+‘s AMD Ryzen V1500B has no integrated GPU, so Plex cannot use hardware transcoding on it. Every transcode runs in software on the CPU, which limits how many streams, and which formats, the NAS can convert at once. There is no fixed stream count for either box: results depend on the source codec, resolution, bitrate, HDR tone mapping, and subtitles.

Synology’s Intel-based models, such as the two-bay DS225+ and the four-bay DS425+, both with a Celeron J4125, do have Intel graphics, but the J4125 predates Jasper Lake.

If your Plex clients support direct play (Apple TV 4K, NVIDIA Shield, most modern smart TVs), transcoding rarely happens: the file streams from disk to the client with little CPU work. Transcoding kicks in when a client needs a different resolution, codec, or bitrate, which happens most often with phones, web browsers, and remote streams. Since April 29, 2025, Plex also requires a Plex Pass on the server owner’s account, or a Plex Pass or Remote Watch Pass on the viewer’s account, for remote video streaming of personal media.

For households that stream to a mix of devices or share libraries with remote users, QNAP’s Intel graphics are the deciding advantage. For a single user with a modern TV, Synology works fine. Our best NAS for Plex guide covers direct-play planning and the split design where Plex runs on separate compute.

Winner: QNAP. Intel Quick Sync versus no hardware path at all. If Plex transcoding is a primary use case, buy QNAP.

Security Track Record

Security is a real difference between the brands, but less lopsided than their reputations suggest. Both publish advisories (Synology, QNAP), and both have shipped critical fixes in the past two years.

• QNAP. QNAP devices were the target of the DeadBolt ransomware campaign in 2022, which hit internet-exposed NAS running Photo Station (advisory QSA-22-24, rated critical). In December 2024, advisory QSA-24-49 fixed eight QTS and QuTS hero flaws from Pwn2Own Ireland 2024, including an improper-authentication bug (CVE-2024-48859) and a command-injection bug (CVE-2024-50393); QNAP rated it Important. In November 2025, advisory QSA-25-45, rated critical, fixed seven QTS and QuTS hero vulnerabilities from Pwn2Own 2025.
• Synology. Synology patched critical Pwn2Own Ireland 2024 flaws in Synology Photos (Synology-SA-24:19, CVE-2024-10443) and in DSM itself (Synology-SA-24:20). In November 2025 it fixed an authentication-bypass flaw in DSM’s single sign-on from Pwn2Own 2025 (Synology-SA-25:14, rated Important).

QTS 5.2’s Security Center, which monitors file activity for ransomware-like behavior, is a useful addition. We still give Synology the edge, mainly because QNAP’s history includes a large ransomware campaign against internet-exposed devices.

The practical advice is the same for both brands. Do not expose the NAS management interface to the internet. Use a VPN or the vendor’s relay service (QuickConnect or myQNAPcloud) for remote access, enable automatic security updates, and disable services you do not use. QNAP’s own DeadBolt guidance was to turn off router port forwarding and use myQNAPcloud instead.

Winner: Synology, narrowly. Both vendors ship serious fixes; QNAP’s ransomware history is the bigger warning for anyone tempted to expose a NAS to the internet.

Mobile Apps and Remote Access

Synology’s mobile lineup centers on Synology Photos, Synology Drive, and DS file, with DS cam for Surveillance Station. Synology Photos is free and includes facial and object recognition, which makes it a credible self-hosted alternative to Google Photos. Video Station and its DS video app are not available on DSM 7.2.2 and later, so plan on Plex, Emby, or Jellyfin for video.

QNAP’s photo app is QuMagie, which also offers AI face and object recognition, with a QuMagie Mobile app; the older Qphoto app has reached end of life. Qfile Pro, Qsync Pro, Qvideo, and Qmusic cover files, sync, video, and music.

For remote access, Synology’s QuickConnect and QNAP’s myQNAPcloud both provide relay-based access without router port forwarding.

Winner: Synology, narrowly. Synology Photos and Synology Drive are more tightly integrated with DSM, although QuMagie closes most of the photo gap.

Upgrade Paths: RAM, PCIe, and Networking

QNAP gives you more room to grow.

The QNAP TS-464 has a PCIe Gen 3 x2 slot that QNAP lists for optional 5GbE and 10GbE network cards. The Synology DS925+ has no PCIe slot, unlike the discontinued DS923+, so its networking tops out at the built-in dual 2.5GbE.

If 10GbE is on your roadmap, look at the Synology DS1525+, a used or clearance DS923+, or another vendor. Do not buy the DS925+ expecting a 10GbE add-in path.

Memory favors Synology: the DS925+ takes 32 GB of ECC DDR4 across two SO-DIMM slots, while the TS-464 tops out at 16 GB of non-ECC memory. For Docker-heavy workloads, that ceiling matters.

Both brands sell expansion units for more drive bays. The DS925+ connects one DX525 through its USB Type-C expansion port, for nine drives in total; older Synology models such as the DS923+ use the eSATA-based DX517 instead. For the TS-464, check QNAP’s compatibility list for supported expansion enclosures.

Winner: QNAP. The PCIe slot is a meaningful upgrade path that the DS925+ lacks. Synology wins on memory ceiling, but we think most home labs hit the network limit before the memory limit.

Who Should Buy Which

Buy Synology if you:

• Prioritize ease of administration, backup tooling, and low-maintenance operation
• Use Active Backup for Business to protect Windows PCs, Macs, servers, or virtual machines
• Plan to use Synology Photos as a self-hosted Google Photos replacement
• Want ECC memory on an always-on storage server
• Mostly direct play your media

Buy QNAP if you:

• Run Plex and need hardware transcoding for phones, browsers, or remote users
• Want a PCIe slot for a future 5GbE or 10GbE card
• Want more hardware for similar money: twice the base memory, HDMI output, and a PCIe slot
• Want more container options (Docker, LXD, and Kata)
• Are comfortable keeping firmware updated and using a VPN for remote access

Bottom Line

For a NAS that is mainly file storage, backup, and a few containers, one you want to set up once and trust for years, Synology is the better brand in 2026. DSM is our preferred NAS operating system for ease of administration, and DSM 7.3 removed the biggest objection to Synology’s 2025 lineup. Since DSM 7.3 (October 2025), Synology’s 2025 Plus, Value and J models, such as the DS925+ and DS225+, accept third-party 3.5-inch HDDs and 2.5-inch SATA SSDs, but M.2 storage pools and cache still need drives on Synology’s compatibility list.

If the NAS doubles as a home-lab server, with Plex transcoding, a PCIe network card, or a heavier container stack, the QNAP TS-464 is the better buy, which is why our 4-bay and home-lab guides pick it. Pair either with drives from our best hard drives for NAS guide, and see our 4-bay NAS comparison for model-by-model breakdowns.
