Operating system comparison – DSM vs QTS

Both Synology and QNAP units will arrive with their own desktop user interface packed in a proprietary operating system. Of course, you can still access a NAS device the traditional way (as a network drive) and through an IP address – from a Windows, MAC or Linux. But with the latest additions, you can also access a complete desktop environment along with a multitude of first and third party applications – this can either be done via an Internet connection or from an internal network.

Both Synology and QNAP units offer support for PLEX Media Player  – one of the main reasons why users decide to purchase a NAS device. However, QNAP units are more efficient with transcoding than Synology counterparts. If you’re mainly looking for a NAS capable of giving you the best experience with a Plex Media Server, go for a QNAP unit.

But which desktop interface is better overall? Well, it really depends on which type of OS approach you are more fond of.

Synology – DSM

The Synology desktop environment resembles closely the MacOS model. It uses Diskstation Manager (DSM) as the primary operating system. You’ll do most of your interactions with it unless you’re using 3rd party applications like Apple Time Machine, Plex or a DLNA streaming service. If you’re curious about the capabilities of the DSM operating system, you can try a free demo from a desktop device (here).

Everything is as simple as possible, and the accent is clearly on intuitiveness. This is certainly eye-pleasing and accommodating for newcomers, but if you’re a technical person you might quickly grow infuriated with the fact that the technical details are tucked away into hidden layers.

The Synology desktop model features a lot of default actions. A lot of things will happen in the background (without you knowing about it). This is a good thing if your only interested in keeping your data safe, but the average geek won’t take kindly to default actions that happen without user authorization.

On the upside, Synology’s first-party apps are superior to QNAP with some great office applications (Document, Spreadsheet, and Slides), chat app (Synology Chat), email client software (MailPlus), facial recognition application (Synology Moments) as well as a drive application (Synology Drive).

QNAP – QTS

QNAP, on the other hand, takes from the Android and Windows model. QNAP Turbo (or QTS) shares much functionality with Synology’s DSM, the QTS operating system doesn’t shy away from showing a lot of technical information. By placing a lot of technical information at the forefront, the user feels that it has more control over the device.

This approach will allow you to configure and tweak far more items that can ultimately lead to an environment that is closer to your personal preferences. You can explore file sizes with a simple mouse hover and see CPU & RAM usage with a single click.

Even more, you will be able to monitor the NAS device temperature as well as a real-time state of your available storage space. In fact, with a single click, you will see a half-screen worth of information about your NAS – charts, graphs and usage patterns. It’s geek heaven. You can try out a live demo fo QNAP’s QTS operating system from this link (here).

This technical perspective is certainly enjoyable by a technical individual, but a newcomer might feel a little bit intimidated by the amount of information present on the screen at any given time.

While QNAP’s first-party applications are somewhat limited when compared to Synology’s options, QNAP units are designed to work with a large fleet of third-party applications. For example, you can install unofficially supported software such as Kodi, Netflix as well as a large selection of QNAP homebrew applications that were birthed on QPKG development forums.

Which NAS has the better operating system?

Again, it all depends on your personal preferences. If you built the PC on your own and you like to tinker quite a bit, a QNAP unit is probably the better NAS for you. A QNAP unit is also recommended if you mainly need a NAS capable of transcoding your Plex needs to a wide array of devices.

If you’re a fan of hidden layers and don’t care much for technicalities, Synology is the easy choice. Although the DSM makes things a lot easier for the newcomers, tech-savvy users might feel like they’ve hit a glass wall sooner than QNAP users.

Mobile Accessibility Comparison

All the latest Synology and QNAP units will give you access to a suite of mobile applications for Android, iOS, and even for Windows Mobile. If you plan on access your NAS device from a mobile phone, it’s important to be aware of what each brand has to offer.

Bottom line is, both Synology and QNAP NAS devices have suites of applications that are designed to work over the internet. But which company does it better?

Synology

Synology has about 10 first-party applications that are designed to run on mobile. DS audio, DS cam, DS file, DS finder are all part of the Synology suite and are designed to put simplicity in the first place. While some users might appreciate that the interface of all Synology applications is not crowded with too much information, technical users might find them quite limiting.

You can use DS Photo for picture access, DS Video for video playback and DS File for general access. In addition to this, you have a separate selection of first-party apps designed for easy download, synchronization, and surveillance. Again, the focus is clearly on making them as accessible as possible, so don’t expect any technical layers to them.

Unfortunately, Synology does not offer third party support in the mobile realm. But it sort of makes up for it with an enhanced degree of stability (within all mobile applications).

QNAP

Qnap has a much larger fleet of first-party applications for mobile (about 15). But setting the apps that they built themselves aside, QNAP supports a multitude of third-party applications that will net you enhanced functionality from a mobile device.

QFile, QVideo, and QMusic are pretty self-explanatory mobile applications, but you also have a collaborative note-taking application (Notes Station), as well as a Remote control app (QRemote). This might not seem like much – and it really isn’t if you stop here. However, the real power of QNAP applications comes from the fact that you can couple them with other apps like IFTTT and IoT to create a personalized mobile experience.

However, due to the fact that QNAP units are designed to work with a multitude of applications (first and 3rd-party), some things are bound to go wrong. With this in mind, expect to experience some instability if you experiment with different third-party mobile applications.

Which NAS has the better mobile applications?

Although QNAP arguably has the better suite of mobile apps for their NAS units, you might experience some instability if you like to tinker with the possibility and refine the process as much as possible.

If you don’t want to miss on the ability to use other third-party applications with your NAS unit, don’t’ look beyond QNAP. However, if you prefer simplicity and stability over the ability to tinker with different connectivity possibilities, I would pick a Synology unit.

Hardware Specifications

Now that we worked out the distinctions between Synology and Qnap when it comes to the software aspects, let’s take a look at the hardware specifications. Like for like, the specifications on Synology are lower than the ones on Qnap units. However, that doesn’t mean that you’ll be at a disadvantage if you end up buying a Synology unit.

It really depends on whether you really need to spend additional bucks on enhanced hardware specifications or not.

QNAP

Although Qnap units can be characterized as network and internet access products, the brand puts the emphasis on localized access – this is why a lot of Qnap units will ship with a remote control.

Even more, most Qnap units include an HDMI port, more PCIe expansion slots,  Thunderbolt connectivity and a direct attach USB port on the front of the unit that lets you access the NAS unit via a USB connection. When it comes to the processing power (without comparing model vs model), Qnap has the better overall specifications  (better range of CPU and RAM frequencies).

Of course, all these hardware options will most likely translate into a higher price tag, but it’s well worth it if you’ll actually end up using these hardware additions.

Synology

Synology is true to the MacOS approach and advertises itself as a network and internet access product. While Synology might not give you superior specifications, it does a much better job at keeping the network standards as high as possible.

Which NAS has the better hardware specifications?

QNAP units are better when it comes to pure specifications and connectivity slots. However, if you don’t really need to use your NAS for localized access chores, I’d say you should go with a Synology unit as they tend to work flawlessly with all internet-based data exchanges (as long as you stay within their ecosystem).

Surveillance capabilities

In terms of surveillance, both QNAP and Synology units are pretty even on the hardware front. Both of them have their own surveillance software. Depending on the unit you end up buying, expect your NAS to support anything from 10 to 50+ cameras in a shared environment – of course, this is dependant on the model you end up buying.

Right from the get-go, it’s worth mentioning that both NAS solutions are perfectly capable of functioning as a surveillance solution for homes, shops, and offices. Both units are equipped to help you monitor all areas of your home or business with a live view interface

But the two companies have different software to support their surveillance capabilities, the way they go around doing this entirely different.

QNAP

Unsurprisingly, QNAP has gone for the detailed route, giving their users more options to choose when it comes to analyzing and managing the camera feeds. Now, the good news is that QNAP has recently released a new version of their camera software (QVR Pro), which is much more user-friendly and accessible than the previous version.

QVR Pro will give you a greater density of control of root patterns, better feed access and better overall camera support with more included camera licenses. In addition to this, it supports Nightvision functionality, motion detection, heat detection and more – of course, this all depends on the cameras that you’ll end up using.

Synology

Loyal to the focus of the brand, Synology’s surveillance support offers easy and accessible access surveillance route. You have the usual features like scheduling, noise alerts, notification alerts, SMS alerts and more, but all of these features have limited customizing options.

Similar to QVR Pro, Synology’s surveillance software (Surveillance Station) does have support for motion detection, night vision, heat detection, PZT and audio recognition.

Surveillance Station is the perfect choice if you’re new to the process of collecting the feed from CCTV cameras, go for a Synology unit.

Which NAS has the better surveillance capabilities?

Although the two NAS brands are pretty even when it comes to the features surveillance software that they use, QNAP has to be the winner in this segment. I say this not only because QVR Pro arrives with much more camera licenses and with more customizing options, but because most QNAP units have HDMI port and keyboard & mouse support, which allows you to transform the unit into a standalone surveillance center.

RAID Configuration Options

Another popular reason why users turn their attention towards a NAS is the ability to protect against data loss due to hardware failure via a RAID (Redundant Array of Independent Disks) system. In a RAID system, the data is duplicated and spread among multiple drives – so if one drive ends up breaking, the lost data can be recreated thanks to the RAID system.

When it comes to the available options when it comes to the RAID Configuration Options, Synology is at a clear advantage. While both QNAP and Synology units support the traditional RAID levels (RAID 0, RAID 1 and RAID 5, RAID 6 and RAID 10), but Synology NAS units support something called Synology Hybrid RAID (SHR). the SHR system grants the ability to have a RAID system consisting of mixed drives – this is not supported on QNAP units.

While there are few reasons why you would buy drives consisting of different sizes, the SHR system is a nice addition considering the fact that a few years from now you might be forced to buy a bigger drive due to storage shortage.

Which NAS has the better RAID configuration options?

Because Synology supports more than the traditional RAID system, their NAS units are superior from a RAID configuration perspective due to the fact that the SHR system allows you to introduce a new drive with a different size without causing instability and other problems.

QNAP units are only equipped to support the traditional RAID system where everything has to be the same. If you introduce different drive, a traditional RAID system will treat it as the lowest capacity model drive. For example, if you introduce a 5 TB drive to a RAID configuration that has 2 TB x 2 TB x 2 TB x 2 TB, a traditional RAID system will only see the new drive as a 2 TB drive. Whereas, if you use Synology’s SHR system you’ll have better feature grouping if you want to use different drives for a RAID system.

NAS File System Comparison – BTRFS vs EXT 4

Even though this happens in the background without affecting the end-user, it’s worth it to be aware of the file system that is used by your NAS to manipulate data and processes.

Keep in mind that most of QNAP and Synology units have EXT 4 as the file system. But top-tier Synology NAS units have the option to use BTRFS as the default file system. BTRFS is similar to EXT 4, with the exception that it supports background data integrity checks without affecting the overall performance of the system. Even more, the BTRFS system has much faster RAID building and re-building times.

As of now, QNAP didn’t adopt the BTRFS as a file system on any of their models – but there is a rumor that they soon will. Hoverer, premium QNAP units have the option of using ZFS – a combined file system superior to EXT 4 and BTRFS.

QNAP vs Synology

If you’re more of a technical-minded individual and you like to tinker with your NAS system, go with a QNAP unit. But don’t get me wrong, you don’t have to be the extremely tech-versed to use a QNAP NAS. It’s just that all QNAP units have better customization options with an overall better coverage for those of you with a technical mind.

On the other hand, if you want a NAS that does what it’s told with a focus on user accessibility, go for a Synology unit. And even if this is not a given rule in all aspects, Synology units are considered to be a touch more stable and reliable.
