Qnap vs Synology: Which NAS Should You Buy?

QNAP and Synology are the two biggest names in consumer and small-business NAS (network-attached storage), and the choice usually comes down to hardware value versus software polish. QNAP typically offers more powerful hardware and more ports for the same price, while Synology’s DiskStation Manager (DSM) is widely considered the more intuitive and stable operating system. This guide compares the two across performance, software, security, and value so you can decide which fits your needs.

Background: How Each Brand Got Here

Synology was founded in 2000 and launched its first NAS in 2004, focusing on a user-friendly operating system from the start. Its DiskStation Manager (DSM) is a web-based OS that feels like a desktop environment, with a package center for adding apps. QNAP (Quality Network Appliance Provider) started in 2004 and also targets both home and business users, but has traditionally emphasized hardware expansion and virtualization features. Over the years, Synology has built a reputation for software stability and frequent updates, while QNAP has pushed higher-spec hardware with more RAM, faster CPUs, and more ports (like 2.5GbE or 10GbE) at lower prices.

Hardware and Performance: QNAP Usually Wins on Specs

For the same price, QNAP typically offers better hardware. Compare two similar 4-bay models: a QNAP TS-464 and a Synology DS923+. The QNAP has a quad-core Intel Celeron N5105 (or similar) and often includes 2.5GbE ports, while the Synology may use a lower-end CPU or require a separate adapter for 2.5GbE. QNAP also offers more models with PCIe slots for adding 10GbE cards, M.2 NVMe caching, or extra USB ports. If you need raw throughput for video editing, large database files, or many simultaneous users, QNAP’s hardware advantage is real.

However, raw specs aren’t everything. Synology’s DSM is lighter on resources, so a lower-powered Synology can feel snappier in everyday file operations than a QNAP with more RAM but heavier software. Also, Synology’s newer models (like the DS923+) use AMD or Intel CPUs that support ECC memory, which can matter for data integrity in a small business. For most home users, both are fast enough for file sharing, Plex media streaming, and backup.

Software: DSM vs QTS/QuTS hero

Synology’s DSM is the gold standard for NAS usability. It has a clean, intuitive interface, a comprehensive package center (with official apps like Synology Photos, Drive, and Active Backup for Business), and a mobile app that works well. DSM also has a built-in virtual machine manager, but it’s not as flexible as QNAP’s Virtualization Station. Synology’s software updates are frequent and reliable, and they have a strong track record of patching security vulnerabilities.

QNAP’s QTS (for consumer models) and QuTS hero (for enterprise models with ZFS) are more feature-rich but also more complex. QTS has a package center with hundreds of apps, including a full Linux environment (Container Station) and a better virtualization platform. However, QTS has had more public security incidents in recent years, including ransomware attacks targeting exposed QNAP devices. QNAP has improved its security, but it still requires more manual configuration to lock down. If you’re not comfortable with port forwarding and firewall rules, Synology is safer out of the box.

Security and Reliability: Synology Has a Better Track Record

Both brands have had security issues, but Synology has historically patched vulnerabilities faster and has a more robust default configuration. QNAP devices were hit hard by the Qlocker and DeadBolt ransomware in 2021-2022, which exploited default settings and exposed ports. QNAP has since added features like automatic blocking of brute-force attacks and a security counselor, but the damage to its reputation remains. Synology also had a few CVEs, but they were less exploited. For critical data, Synology’s DSM is generally considered the safer choice, especially for less technical users.

How to Choose: A Decision Guide

• Choose Synology if: You want a hassle-free setup, a clean interface, and reliable automatic updates. You’re a home user or small business that needs file sharing, backup, and media streaming without tinkering. You value long-term software support and a lower risk of ransomware.
• Choose QNAP if: You need maximum hardware performance for the price—more RAM, faster networking, or PCIe expansion. You’re comfortable configuring security settings and want advanced features like virtualization, containerization, or ZFS (on QuTS hero models). You have a larger budget for higher-end models with 10GbE.
• For media streaming (Plex): QNAP’s faster CPUs often handle 4K transcoding better, but both work with Plex. Check the specific model’s CPU and whether it supports hardware transcoding.
• For backup: Both support Time Machine, rsync, and cloud backup. Synology’s Hyper Backup is more user-friendly, while QNAP’s Hybrid Backup Sync is comparable.

Common Problems and Misconceptions

A common misconception is that you must choose one brand for all your needs. In reality, you can mix—use a QNAP for media and a Synology for backup. Another issue: many users buy a NAS without checking if their drives are on the compatibility list. Both brands have compatibility lists; using non-listed drives can cause warnings or performance issues. Also, don’t forget that a NAS is not a backup by itself—if it’s stolen or damaged, you lose data. Always set up a 3-2-1 backup strategy (3 copies, 2 different media, 1 offsite). Both brands support cloud backup to services like Backblaze B2 or Amazon S3, but you’ll pay for storage.

Costs and Value

Entry-level 2-bay NAS units from both brands cost roughly $150-$250 without drives. At the same price, QNAP often includes more RAM (e.g., 4GB vs 2GB) and faster networking. However, Synology’s software is a major value-add—you get a polished OS that would cost extra elsewhere. For higher-end models (4-bay and up), QNAP’s hardware advantage grows, but Synology’s DSM is still more polished. Also consider the cost of drives: NAS drives (like WD Red or Seagate IronWolf) are recommended for 24/7 operation, and they add $100-$200 per drive. Don’t forget to factor in a UPS (uninterruptible power supply) to protect against power outages, which can corrupt data.

Alternatives to Consider

If you’re not set on these two, other options exist. TrueNAS (formerly FreeNAS) is a free, open-source NAS OS that runs on your own hardware—powerful but requires more technical expertise. Unraid is another popular option for home labs, with easy drive pooling and a large app ecosystem. For cloud-only users, services like Google Drive or Dropbox are simpler but lack the privacy and capacity of a local NAS. If you need a simple two-bay backup device without apps, a single-bay external drive might suffice. But for most people who want a dedicated, reliable NAS, Synology and QNAP remain the top choices.

Frequently Asked Questions

Which is better for a beginner?

Synology is better for beginners. DSM’s interface is more intuitive, setup wizards guide you through drive creation and shared folders, and the default security settings are safer. QNAP can do everything Synology does, but it requires more manual configuration to avoid security pitfalls.

Can I use QNAP and Synology together?

Yes. You can have both on your network. For example, use a QNAP as a media server and a Synology for backup. Both support rsync, so you can back up one to the other. Just ensure they are on different IP addresses and both have strong passwords.

Which brand has better Plex support?

QNAP generally has better Plex support because its CPUs are often more powerful and include Intel Quick Sync for hardware transcoding. However, high-end Synology models also support hardware transcoding. Check the specific model’s CPU and Plex compatibility list before buying.

Are QNAP devices more vulnerable to ransomware?

Historically, QNAP devices have been targeted more often, especially when users expose them to the internet without proper security. Synology has had fewer incidents, but no NAS is immune. For both, disable UPnP, use strong passwords, enable two-factor authentication, and keep firmware updated.

Can I run Docker containers on both?

Yes. Synology has Container Manager (formerly Docker) and QNAP has Container Station. Both support Docker images. QNAP’s Container Station also supports LXC, but Docker works on both. Performance will depend on the CPU and RAM of your specific model.

Which has better mobile apps?

Synology’s mobile apps (DS file, DS photo, DS video) are more polished and reliable. QNAP’s Qfile and Qphoto are functional but less refined. If you’ll access your NAS mainly from a phone, Synology’s apps are a plus.
