Part 3. QNAP vs. Synology: Operating Systems Compared

Now that you have a brief background on these two companies and know how popular they are, it’s time to dig a little bit deeper. Here is what you need to know about using OSs QNAP and Synology.


QNAP NAS uses QNAP Turbo Station or QTS operating system based on Linux. It comes with its own application manager called App Center. The user interface looks neat, and it resembles the Mac OS. The list of options and settings is comprehensive, which might pose a challenge to people using NAS for the first time.

The same goes for the items in the settings and options menu. They are all technical terms meaning that you need to at least know basic networking terminology to use it properly.

QTS comes with a bunch of additional apps you can use through the App Center.


Synology OS is called DiskStation Manager or simply DSM. It’s also Linux-based and has a built-in application manager called Package center. Unlike QTS, which resembles Mac OS, DSM looks a lot like Windows. If you know your way around the Windows OS, you will find it easy to navigate DSM too.

The user interface is significantly more intuitive than the one of QTS. All settings and options are developed with user-friendliness in mind, thus making DSM beginner friendly.

This round of QNAP vs. Synology match goes to Synology because it delivers a more user-friendly interface that can shorten onboarding time. While both have application managers, DSM offers access to more apps. Plus, some apps and options, such as Antivirus and VPN, are missing in QTS, and they are available in DSM. That clearly makes Synology a winner in the QNAP vs. Synology security comparison.

Part 4. QNAP vs. Synology: Hardware

In terms of hardware, you are looking for upgrade capabilities of a NAS system, as these capabilities can prove crucial when you need to scale up your setup and get the most out of it.


When it comes to hardware, QNAP provides numerous configurations to choose from. You can select a configuration with a specific amount of RAM, CPU model, LAN connection type, etc. It offers more flexibility and enables you to get a configuration that can support your future needs.

QNAP offers more units in each category it shares with Synology. It means that you will have more options to choose from, which is a tremendous advantage for advanced users. At the same time, it may be overwhelming for beginners who will find Synology’s less flexible inventory more attractive.

Part 5. QNAP vs. Synology: Backup Systems

Most of the users decide to start using NAS for backup purposes. As you might have expected, both QNAP and Synology offer backup systems. However, you may not know that their backup services are not the same.


QNAP NAS units don’t ship out with a comprehensive backup system. The built-in one is quite basic as it comes with an on-demand backup option you need to click every time to back up your data. You must find relevant apps such as Boxafe, Duplicacy, and ElephantDrive. When searching for the right backup app on QNAP App Center, you should consider your additional backup needs. You might need to schedule a daily, weekly, or monthly auto backup, backup to the cloud, or do incremental backups on demand.


Synology offers a more comprehensive solution. Its NAS units use the Hyper Backup application. It’s a completely free tool you can use to back up your data to a range of endpoints, including rsync servers and cloud storage. With this tool, you can automatically back up data, installed applications, and specific configurations.

Part 6. QNAP vs. Synology: File Systems

QNAP and Synology don’t support the same file systems. Let’s see the differences and why they matter.


Most QNAP NAS units only support the EXT4 file system, making QNAP NAS data recovery challenging in RAID systems. Only the QNAP enterprise rack-mount units have support for ZFS with volume management capabilities.


On the other hand, the Synology NAS units support both EXT4 and BTRFS file systems. Why does it matter?

Thanks to the BTRFS file system, you can streamline Synology NAS data recovery. You can efficiently build or reconstruct your RAID systems as this file system does data integrity checks in the background.

Part 7. QNAP vs. Synology: RAID Levels

RAID is a perfect solution to thwart the risk of data loss due to hardware failure. Both QNAP and Synology offer various RAID configuration options, but there is a subtle yet meaningful difference. Here’s the deal.


QNAP systems offer support only for the typical RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, TP, and TM. It means that everything in your setup has to be identical. While you can use different drives to replace a faulty one in RAID in terms of model and manufacturer, you will have to use the model with the same capacity or larger.

However, if you use a larger capacity drive, QNAP will render the extra capacity unusable. That’s why the recommendation is to use a drive of the same capacity as the faulty one. That’s where Synology has more to offer.


Synology NAS units come with superior support for RAID levels. More specifically, you can benefit from Synology Hybrid RAID or SHR (SHR and SHR-2). It simply means you can use different discs to build your RAID system, making the entire process hassle-free.

What’s the bottom line? If you have different discs, it’s better to choose Synology. However, if you use the same discs, you can go with QNAP. You just need to be mindful that in the case of hardware failure in the future, you will have to replace discs in your RAID system with the exact models.

Part 8. QNAP vs. Synology: Access management

Both QNAP and Synology NAS units come with software to help you streamline access management. Here are the noteworthy facts of Synology QNAP comparison in this category.


QNAP offers advanced access management configuration for less conventional file types such as RAR, GIF, and MKV. You can get many access management apps from App Center to streamline access management.


Synology NAS units also have access management capabilities, but they are more suited for conventional file types such as PDF, MP3, DOCX, and AVI.

Part 9. QNAP vs. Synology: Customer support

Customer support is the final factor you must consider when choosing QNAP vs. Synology.
