Synology and QNAP dominate the NAS market with distinctly different philosophies. Synology prioritises software polish and simplicity; QNAP offers more powerful hardware and flexibility. This detailed comparison helps you choose the right platform.
Software: DSM vs QTS
Synology DiskStation Manager (DSM) is widely regarded as the most polished NAS operating system. It’s intuitive, stable, and receives consistent updates. QNAP QTS offers more features and customisation options but has a steeper learning curve and occasionally feels less refined. For first-time NAS users, Synology’s software advantage is significant.
Hardware Value
QNAP consistently offers more powerful hardware at equivalent price points — faster processors, more RAM, 2.5GbE networking, and HDMI output are standard on mid-range QNAP models. Synology tends to use lower-powered processors and charges a premium for features like 10GbE that QNAP includes more readily.
| Feature | Synology DS923+ | QNAP TS-464 |
|---|---|---|
| Price | ~£500 | ~£450 |
| CPU | AMD Ryzen R1600 | Intel N5095 |
| Default RAM | 4GB | 8GB |
| Network | 2x 1GbE | 2x 2.5GbE |
| M.2 Slots | 2 | 2 |
| HDMI | No | Yes |
Security Track Record
Synology has a better security track record. QNAP has experienced several high-profile ransomware attacks (DeadBolt, Qlocker) that specifically targeted QTS vulnerabilities. While QNAP has improved its security posture, Synology’s track record gives it an edge for security-conscious users. Both recommend against exposing NAS directly to the internet.
App Ecosystem
Synology’s first-party apps (Photos, Drive, Surveillance Station) are polished and reliable. QNAP offers more third-party app support and container/virtualisation capabilities. For Plex users, QNAP’s more powerful hardware often provides better transcoding performance. For backup and file sync, Synology’s Hyper Backup and Drive are industry-leading.
Our Recommendation
Choose Synology if you want the easiest setup, best security, and most polished software — especially for first-time NAS users. Choose QNAP if you want the best hardware value, need HDMI output, or plan to run virtualisation and containers extensively.
Frequently Asked Questions
Which NAS brand is more reliable?
Both brands use quality components. Synology has a slight edge in software stability and security track record.
Can I switch from QNAP to Synology?
You would need to migrate data to an external drive, set up the new NAS, and restore. RAID arrays are not cross-compatible between brands.
Which NAS is better for Plex?
QNAP typically offers better Plex performance at equivalent price points due to more powerful processors and more included RAM.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
