Plex Media Server Vs Synology Video Station on a NAS

One of the most popular reasons that users choose to buy a network-attached storage (NAS) device is for use as a media server. The appeal is pretty clear. With most users now owning decades of media (either in digital form or ripped from optical media at home), the ability to enjoy these box sets and Movies on the latest devices can be complicated. Despite this, streaming all of your multimedia from a NAS to all of your TVs, phones, tablets and other devices are growing increasingly popular and a lot of this is thanks to the increasing affordability of NAS from brands like Synology and QNAP and free software from companies like Plex and Emby. The most popular NAS for home media tends to be Synology, with its support of numerous media server applications and its own premium video service app too. This combined with the oversaturation of third-party online streaming services that ask you to pay a subscription (such as Netflix) with little control or right to ownership of the media you watch means that many users just want to enjoy their own unique media collections. So now that a lot of users are choosing to switch from the likes of Netflix and Prime Video towards an in-house media server, the next question is which piece of software they should choose.

The most popular private media server app right now worldwide to counter the likes of Netflix is Plex Media Server, software available in host and client form that allows you to transform your media collection into a glossy, slick and informative UI that genuinely rivals big online streaming platforms. Synology on the other hand would likely prefer users to stick with their own fully-featured media server application, Synology Video Station, which they have invested well in and developed to an impressive standard that easily rivals that of Plex. So today I want to compare these two media server choices and help you decide which one is the ideal media server choice for you.

Important – ‘Free’ Vs Paid Media Server Services on a NAS

Before going any further, it is worth addressing the elephant in the room, namely that a number of key media server services that are included with Plex Media Server are locked behind a paid subscription service known as Plex Pass. Whereas Synology Video Station is an application that is included with your NAS on Day 1 at no additional cost. All that said, neither service can technically be called free, as both still require you to purchase a Synology NAS. Additionally, it is still worth highlighting that some more recent Innovations in Plex online services and utilisation of hardware transcoding (the ability to use the CPU’s embedded graphics or an available graphics card to adapt files on the fly to make them better suited to a client) is not available on the free tier of Plex, but ARE available by default in the Synology Video Station application. You can still utilise software transcoding on Plex for free and this will deal with a large degree of transcoding requirements, but the fact that you have to pay extra within the Plex app to utilise the hardware already available on your NAS is something a number of users find difficult to accept. Throughout this article, any feature that is only available as a paid Plex Pass feature will be highlighted as such.

Plex VS Synology Video Station – Installation and First Time Setup

Installation of either the Synology Video Station or Plex Media Server application is near enough identical. Both are readily available in the Synology app centre and can be installed within two clicks. Both media server applications do not require your multimedia files to be stored in a pre-designated/directory location and the sources for TV shows, Movies and more can be scanned and indexed by each media server application after they are installed. In fact, the initial installation on both is incredibly straightforward and there is really only one main difference between them. That difference is that whereas the Synology Media application uses your original NAS login credentials, Plex will require you to set up an account with them online in order to use the software, even if you only intend to use your Plex Media Server on the local network/DLNA. As Plex is a third-party application, this is a little understandable if a tiny bit annoying for some. 

It is also worth highlighting that both media server applications will receive regular updates during their lifespan and this is treated slightly differently too. As Synology Video Station is a first-party app, as soon as an update is available, you will be notified immediately in the app centre and even have the opportunity to apply these firmware updates automatically. Plex updates on the other hand will almost always need to be installed manually, as the available default Plex application on the Synology app centre is updated considerably less frequently and as soon as you setup Plex for the first time, it will ALWAYS inform you that there is a new update available straight away. The Plex Media Server application itself will tell you when an update is available regularly at the top right and in the settings menu, but requires you to download the latest Plex server update to a connected computer and then you need to upload this update directly to the Synology NAS app centre manually. It is only a small inconvenience really, but does mean that regular updates on your media server of choice are handled more easily and with likely more frequency on Synology Video Station rather than Plex.

Plex VS Synology Video Station – GUI, Media Support and Browsing

The user interface of Synology Video Station and Plex Media Server are quite similar when viewed on a client device, such as a console, TV and Amazon Fire TV stick. With all of your available Movies and Boxsets clearly shown and the metadata collected by each media server application creating a great user interface for your connected users. 

However the back end/server view of each media server application is considerably different and where the Synology Video Station application is designed exclusively around video media options and configuration (as Synology have a wide range of applications for different Media types and general NAS server maintenance already available), Plex, on the other hand, is a far better equipped tool for a complete server, with the bulk of server maintenance and customisation options built into the single Plex GUI. If you are something of an IT novice, the wide range of options that Plex Media Server throws at you for system maintenance can be a touch intimidating and because Plex is designed around many different kinds of media support (something we will touch on later) it’s configuration needs to be noticeably broader than the video-centric options in the Synology official video application. These additional options, if you take the time to go through them, will definitely lead to a better media server user experience and a far better multimedia streaming system overall, it’s just a question of how bespoke and how elaborate you want your media server to be.

As mentioned, there is a clear difference in the multimedia types supported in Plex Media Server or Synology Video Station. In terms of handling of video Media, they are near enough identical with some exceptions with regard to specialist audio handling for certain dense Media. However, much like the back-end server control mentioned earlier, Synology Video Station only handles video media and relies on alternative applications such as Synology moments, photo station, Synology photos, audio station and download station to play and obtain other kinds of multimedia. Plex Media Server is a much more diverse multimedia tool with support of your photo collections (AI-assisted too), album collections, podcast streaming and several online video streaming services included. In both cases, it makes a lot of sense why they are designed this way, but some users may prefer their media server to be more of a Swiss army knife and others may want their video streaming, music streaming and photo streaming to be different services for different devices and clients. Neither Plex or Synology Video Station really gain any advantage here but simply show how they are different in their architecture. If you want simplicity in the user interface, go with Synology Video Station. If you want simplicity in your media server as a whole, go with Plex Media Server.

Plex VS Synology Video Station – Meta Data Scraping

The scraping of metadata in a media server is precisely what separates a bog-standard selection of files and folders on your screen from a slick graphical user interface that is engaging, informative and a joy to use. When we talk about metadata, we are talking about thumbnails, box art, media descriptions, cast listings, review scores, trailers and more. When we say scraping, that is the process of the software accessing numerous online databases to retrieve and store this information locally to the NAS. The result is your years of TV and movie collection being transformed into something near identical to Netflix and Amazon Prime video in presentation. Metadata ultimately benefits connected users and their client hardware devices, with both Plex and Video Station being very similar in how they look to a client device, albeit with a few branded differences in colour and config.

However, on the server-side, both Synology Video Station and Plex have gone a different way with metadata scraping at a setup level. Of the two, Synology Video Station is definitely the less option-heavy and although this is thanks in many ways to a lot of key options being found in the general server GUI outside of the app, it is still pretty thin on the ground for configuration of your video media server. This is not an enormous surprise given how Synology have generally erred towards keeping things as user-friendly as possible and this is often done by simplifying configurations and sitting numerous settings to system default. The options for scraping metadata on the Synology are surprisingly thin on the ground and some more advanced options require you to sign up to some resource database websites to obtain a two-way key. Despite this, Synology still manages to scrape a tremendous amount of metadata without this key and resource linking. Indeed, although the number of supported databases for metadata listed on the Synology Video Station app is few and far between, it was still able to find the same level of metadata found on the Plex Media Server application and displayed all of the test media perfectly. 

Plex Media Server has access to significantly more online databases and although the system will generally ask you to select which one individually you wish to scrape for metadata in each library, it does do it with a high degree of accuracy. It also manages to scrape this metadata for more than just your Movies and applies this also to your music collection and podcast collection too within the app. Metadata scraping via Plex Media Server also does not require any kind of log-in to these individual databases and is largely automated off the bat, with users being able to switch designated databases for each Media type and folder on the fly. Of course, this all doesn’t guarantee accuracy and will still always be based on the format and layout of your Media in many cases (tv shows listed as S01E01 for season 1, episode 1, etc), but nevertheless, it has to be said that with more available resources and less configuration required for each of them, that Plex Media Server has the broader and more likely to succeed position on metadata scraping.

Plex VS Synology Video Station – Playback and Transcoding

This is one of the most important parts of any media server in the grand scheme of things – multimedia playback and transcoding. This is typically the action of changing a media file into a version that is more acceptable to the client device that you are enjoying it on (TV, Phone, Console, etc). This extends to but is not limited to, changing the resolution, changing the bitrate, changing the file format and ultimately compressing a file into a smaller version in most cases. Because Plex and Synology Video Station are available on the same NAS system, it means that media variations with regard to codecs, compressions and file types will be equally supported at the default level. If a file can be played back in its original version on Plex, it can be played back on Synology Video Station. However, it is when these files need to be adapted with transcoding that we see clear distinctions between each of them. Transcoding is something that remote accessing client users will likely use without even realising it, as they might well be on a limited data connection (speed or coverage at the time) or using a smaller device (such as a phone) to playback a monster 4K 60FPS movie that is overkill on that hardware. So, transcoding is at its best when you do not notice it is being done OR it is adaptable in as many ways as possible to cover all your likely scenarios.

When the NAS needs to perform a transcode on a file on the fly (eg, so you need to convert a video file into a better-suited version for the client watching device upon request and without delay) it will typically do it with software transcoding or hardware transcoding. Software transcoding is when the system uses the raw resources of the CPU and memory inside the NAS to convert the file. Hardware transcoding is when the NAS system features a graphical component (such as embedded graphics featured on a CPU) or an available graphics card that is installed – as these are designed for handling video files and/or graphical manipulation tasks, and will therefore utilise considerably fewer resources. Plex Media Server only provides hardware transcoding in the paid subscription service Plex Pass and then needs to be enabled in the encoding section by selecting the option ‘make my CPU hurt’. Software transcoding is available for the free version of Plex Media Server but is far less efficient and will result in much higher-end Media in 4K and 1080p playback consuming the majority of hardware resources to transcode or will simply not play at all. 

Synology Video Station on the other hand, because it is a native first-party app, has full access to the hardware transcoding element of the NAS and therefore allows users to take advantage of it easily and immediately, and at no additional cost. This has been one of the driving forces behind the popularity of Synology Video Station application, as although the majority of NAS brands have their own video player, Synology is the only one that manages to merge the slick meta-data supported graphical user interface found in Plex but still manages to provide the free and unlimited limited access to the hardware resources you would expect after spending several $100s on a NAS. That said, the way that Synology handles the subject of transcoding in its user interface is a little peculiar, especially for users who are trying to balance the best possible playback vs the most appropriate transcoding level on the fly/manually. 

When you wish for the NAS system to transcode a file in the Video Station user interface, you are presented with the options for adjusting the picture quality to high, medium, low, very low, etc. This is exactly what one might expect from a brand that wants to consistently keep things as simple as possible, however, for those who want to select a specific quality level to playback the file or want a better idea of the best quality level in future should be for other files, this will be extraordinarily limiting. Plex Media Server on the other hand allows you to switch between an automatic transcode option that changes the file to the recommended quality level for the client and connection, or you can specifically switch one of numerous video quality levels that break down into both resolution and bitrate in several places. Overall, the ability for Video Station to be able to take advantage of hardware transcoding at no additional cost and with little or no intervention from the end-user is still ultimately the best thing here. I just wish they gave uses a better degree of control and choice as found in Plex Media Server.

Plex VS Synology Video Station – Client Support

Having a slick and well-performing media server is always good, but if you cannot watch the media inside it on the devices you regularly use, then it’s all a bit pointless. Most people are already well aware that the multimedia collections they have on a NAS can easily be streamed over the local area network via popular methods such as DLNA and UPnP (digital living network alliance and universal plug and play). However, they are much more file and folder, breadcrumb level streaming and in order to enjoy the pretty GUI of Plex and Synology Video Station, an official client app needs to be available on the respective app centre or made unofficially and manually installed. This is an area where Plex Media Server almost completely wins over Synology Video Station, as it simply cannot compete with the variety and accessibility of the Plex client availability in popular app centres. 

Full credit to Plex, they have really taken the time to make sure their platform is available on pretty much any modern device, in what multiple client or media server application forms. They also take the time after an official update of services and then push these updates across each available downloadable client. This is largely impossible for Synology to compete with and they instead opt for a much more targeted client support regime, supporting all modern mobile phone OS’, desktop operating systems and some of the major sofa accessible app centres on TVs and streamers like Amazon fire TV. In  8 out of 10 cases, your device will support both Plex and Synology Video Station, but this is by no means total and sometimes a hardware client (such as an off-brand Android phone, tablet or media box) that you hope to support Video Station will sadly not. 

It is once again worth mentioning that Synology separates different multimedia types towards their own individual client apps, for example, DS Audio or Audio Station for music and DS Photo for photography. Indeed, some of these apps are quite advanced with practically unique connectivity to the likes of Amazon Alexa (something currently impossible on any other NAS platform without a 3rd party application like ‘my-media’ Alexa skill. But this, unfortunately, does not make up for being truly overshadowed by the wider degree of support available on Plex across numerous clients and smart Home devices – though the latter does require a Plex Pass. For sheer volume of connectivity on the clients, Plex wins by an absolute landslide.

Plex VS Synology Video Station – Conclusion

Throughout this comparison of Plex Media Server and Synology Video Station, it has become abundantly clear that one tool is designed around being a Swiss army knife of features and functions, whilst the other performs a smaller but key range of services exceptionally well. Those who have been using Plex Media Server for a number of years are highly unlikely to make the jump to Synology Video Station, as it may feel less feature-rich and perhaps a tad bare-bones. However, those users who are new to the idea of private NAS based multimedia streaming would do very well to try out Synology Video Station first, as I genuinely believe when it comes to concentrating on video streaming services, it is genuinely one of the best platforms out there – albeit clearly restricted to just Synology NAS devices. Plex Media Server attempts to do many things in its pursuit of being the go-to media server of choice for those jumping ship from Netflix and succeeds in most cases, it is just worth remembering that in recent years the platform has perhaps tried to diversify a tad too much.

Synology DS423+ vs DS923+ Plex NAS Comparison – Which Should You Buy?

Today I want to compare the hardware on offer inside the Synology DS923+ NAS (released in Dec 2022) and compare it with the newer and more lower powered, but hugely popular Synology DS423+ NAS (released inin Summer 2023). However, unlike previous comparisons of these two NAS (such as the hardware and software comparison HERE that I published a few months ago) today I want to compare how the DS423+ and DS923+ perform as a Plex Media Server, with a series of 720p, 1080p and 4K tests. I have already tested these two NAS devices individually, but never directly compared their performance side by side. Now that a number of prominent Synology NAS releases have arrived with AMD Ryzeen embedded processors (such as the AMD Ryzen R1600 and V1500), many are wondering if they should choose to buy the older and more affordable Synology NAS drives that still feature Intel embedded/integrated graphics, such as the DS423+ with it’s J4125 Celeron CPU. So, let’s get this test up and running. First, we need to take a quick look at the individual hardware of these two NAS devices.

Synology DS423+ NAS	Synology DS923+ NAS

Synology DS423+ vs DS923+ Plex NAS Comparison – Internal Hardware

These 4-Bay Diskstation releases from Synology have always been one of the most interesting tiers of the brand’s desktop solutions. The reason for this is that all too often this scale of system serves as a bridging point between Prosumer & SOHO systems and the small/medium business hardware in their portfolio. This is demonstrated first in the scale of the available RAID 5/6 storage, but then more so in the scalability and upgradability of these two volumes system, allowing an expansion, greater network connectivity (arriving with 2x LAN ports) and better internal hardware than the more domestic targetted solutions – often with the internal hardware differing considerably between each periodic 2-3yr refresh by the brand. Let’s first look at the internal hardware of these two NAS’ to see how much they differ. The DS423+ NAS first arrived on the scene with some great hardware advantages over the rest of the plus series 2023/2024 systems (DS223, DS124, etc), arriving with a 4 Core Intel Celeron Processor that featured integrated graphics, 4GB of DDR4 2666Mhz memory and NVMe SSD upgrade slots. In the 3-4 years since this hardware configuration was firt released though (the DS920+/DS720+ released in summer 2020), Synology clearly decided to make some big changes in the base level architecture of the plus series and specifically in the DS923+ to make it considerably more scalable and general business/file-ops focused. The newer DS923+ features a dual-core AMD Ryzen embedded R1600 that, although arriving with half the cores of the Celeron in the DS423+, has a higher CPU frequency and total achievable frequency in turbo/burst when needed. That said, users will be surprised to learn that this CPU also does not feature embedded graphics, so therefore the DS923+ will be less CPU efficient at handling multimedia or VM deployment than the DS423+.

Though both systems feature DDR4 memory, the DS423’s maximum 8GB of memory is beaten by the DS923+ thanks to its use of much more impressive ECC (error code correction) memory to identify and repair any bit level write errors and can also be scaled to a considerably higher 32GB of memory (arriving with 8GB by default).

You can find out more about the hardware-specific difference between the Synology DS423+ and DS923+ NAS in the video below OR via the article HERE. This video/article coves everything from the storage capabilities, ports & connections and extent to which they run/perform in DSM 7.1. Although this article is specifically tailored to look at Plex Media Server performance, I would strongly recommend checking out more information on either of these NAS before you make any decision.

Let’s carry on talking about these two NAS and Plex. What difference des the TYPE of media tha you play make on how these two NAS perform in Plex?

Synology DS423+ vs DS923+ Plex NAS Comparison – Understanding MEDIA!

Important Terms to Understand in Plex/NAS/Multimedia that will make the DS923+ or DS423+ NAS Plex Tests Easier to Understand.

• SD, 160p, 240p, 480p, 720p, 1080p, 4K : This is the resolution that the media is being displayed at. The higher the resolution, the larger number of pixels that are available and depending on the original recording quality of the media in question. High resolutions, such as 1080p and 4K require more work to be done by the NAS hardware in order to playback the file. More often than not, a NAS with weak embedded graphics or no embedded graphics at all will be unable to play 4K very well or indeed at all. It is important to remember that just because a NAS brand like Synology says that their latest NAS can natively play back 1080p or 4K media (natively = played using their own NAS software, software client tools and/or DLNA), that does not mean that the DS423+ or DS923+ will play to the same standard in Plex, as Plex is a 3rd party tool
• Transcoding, Encoding, Decoding : These are all different techniques/names for when a file needs to be changed in order to be better suited to the connected client device connection, strength or hardware. If you are accessing all your media on the local area network (i.e only accessing your plex media at home), then transcoding will rarely be something you will use (unless your media is largely H.265/HEVC based, see earlier). However, perhaps you are accessing your plex library on the train to work or from a sun bed whilst on holiday. Perhaps you have a smaller data bandwidth/allowed MB/GB, maybe a weaker internet connection, perhaps you are using a smaller phone device and you might not need to watch your 4K 50GB Blu-ray rip of the latest Marvel Movie – in these situations, you might well want to access the media on your Synology DS923+ or DS423+ Plex NAS at a lesser quality than the original version, so transcoding/re-encoding on the fly (as in, at the same time it is being played) is what you would want to do. Remember, transcoding is by far the most heavy-weight thing you will need to do on a NAS. It is also worth remembering that in order for Plex o be able to use the FULL resources of a NAS CPU (such as embedded graphics) that you will need to enable ‘Make My CPU Hurt’ in the Encoder Menu of the Plex NAS Settings menu – this also potentially requires a Plex Pass subscription, depending on the NAS in question

 

• H.264, HEVC, H.265 :  These are compression techniques that are designed to allow large-scale media presentations that were made for a cinema to be viewable from your sofa (with H.265 being the more effective/powerful compression level). H.264 can largely be played by ALL devices, but many devices do not have permission or a license to play H.265/HEVC (they are the same thing). This is because, where H.264 is an easy license and comparatively free to use, H.265/HEVC licencing and patents are spread across multiple providers and allowing a device license to use this compression technique can be complex, expensive or simply impossible. Therefore HEVC/H.265 media will sometimes AUTOMATICALLY need to be converted/transcoded into H.264 etc in order to be played – therefore eating up more system resources. The DS923+, much like the rest of the Synology NAS range do not arrive with HEVC support by default
• Bitrate : Bitrate is the amount of data encoded for a unit of time, and for streaming is usually referenced in megabits per second (Mbps) for video, and in kilobits per second (kbps) for audio. Higher quality and higher resolution media tends to be of a much higher bitrate

For more information on the most important terms to understand when discussing/researching a NAS as a Plex Media Server can be found in my video below:

Any further questions, you can use the free advice section at the bottom of the page and ask me and Eddie directly.

Synology DS423+ vs DS923+ Plex NAS Comparison – 720p h.264 3Mbps Video File

The first test was with a very low-end 720p media file:

Virtually no difference in performance and you can likely play a considerable number of these files before the system shows even a hint of difficulty.

Synology DS423+ vs DS923+ Plex NAS Comparison – 720p h.264 3Mbps Video File

Another 720p file for test two, similar bitrate to test 1:

Once again, both the DS423+ and DS923+ NAS performed near identically in Plex and zero issues were seen.

Synology DS423+ vs DS923+ Plex NAS Comparison – 720p h.264 3Mbps Video File CONVERT to 480p

Test three was our first transcoding/encoding test. Here I wanted to see how well the systems would cope with having a fle format/playback altered on the fly. If you are watching media on smaller devices, over limited internet connections or using a legacy client device that does not support the file format, compression, codec or scale (size), then transocding is going to be very important. This was 720p down to 480p

Both played the file and transcoded it very easily. Despite the lack of embedded graphics on the R1600 CPU inside the Synology DS923+ versus the Intel J4125 Celeron inside the DS423+, things were great on both in this test.

Synology DS423+ vs DS923+ Plex NAS Comparison – 720p h.264 3Mbps Video File CONVERT to 240p

Time for ANOTHER transcoding test, but this one was s much bigger and more extreme transcode/encode. I wanted to change a 720p file to a 240p file format. This is a pretty aggressive change and one that was mainly picked to simulate heavy Plex NAS use generally (not specific to this format of file/change).

This was the first (and not last) time that the clear advantage of an embedded graphics Intel Celeron CPU inside the DS423+ would prove much more effective in Plex versus the AMD embedded Ryzen R1600 CPU inside the DS923+ NAS. Both NAS devices did the job, but the R1600 / DS923+ had to work much, much hardware with software transcoding and raw power.

Synology DS423+ vs DS923+ Plex NAS Comparison – 1080p h.264 3Mbps Video File

On to 1080p Plex Tests on the DS423+ and DS923+ NAS. This was a fairly domestic HD 1080p file test, played native.

Once again, like the early 720p tests, the DS423+ and DS923+ performed perfectly well.

Synology DS423+ vs DS923+ Plex NAS Comparison – 1080p h.264 3Mbps

A slightly more dense 1080p file this time, using the Jellyfish test files.

Once again, very clear and even performance by both NAS systems in the 1080p 2nd test without any transcoding on the R1600 and J4125 CPU-powered devices. A clear draw.

Synology DS423+ vs DS923+ Plex NAS Comparison – 1080p h.264 3Mbps Video File CONVERT to 160p

Time for more transcoding! Transcoding/re-encoding the 1080p file in Plex to an incredibly lowly 160p. Again, I am aware that few users will actually watch 160p, but many will want this support for audio media equivalent workload and/or for large numbers of streams. Ultimately, we want to know the impact on the DS923+ and DS423+ NAS in plex with these.

Once again, the onboard/embedded graphics that the Synology DS423+ (Intel Celeron J4125) has over the non-integrated graphics DS923+ (AMD R1600) clearly resulted in the older 4-Bay NAS getting this job done with very little fuss. Whereas the Neewer 5-Bay NAS was unable to complete the task.

Synology DS423+ vs DS923+ Plex NAS Comparison – 1080p h.264 100Mbps

Switching things up to an incredibly DENSE 1080p file, I selected the 100Mbps file format (h.264) to see how the DS923+ and DS423+ would play this natively.

Very similar results on both NAS playing the file natively, which was very positive. The DS923+ used the tiniest bit more, but in the grand scheme of things, both of these NAS performed exceptionally well in Plex and this heavy-duty 1080P FILE.

Synology DS423+ vs DS923+ Plex NAS Comparison – 1080p h.265 – HEVC 10bit 10Mbps

Now we move towards a very different ball game. Although the next test was a 10Mbps bitrate 1080p file (remember, the previous test was 10x this density), this time we selected the H.265 / HEVC 10bit file. As mentioned earlier, HEVC (highly efficient video codec) requires licensing by the client hardware manufacturer and software provider (with many/most not including it, relying on the hardware to convert the file to H.264 by default). HEVC is much more space efficient than H.264 and alot more media in 2022+ is arriving in this format. However, converting it (aka Transcoding by another name technically) is a demanding task. Here is how the DS423+ and DS923+ performed:

Once again, the Synology DS423+ and it’s Intel Celeron J4125 CPU got the job done with little-to-no fuss, whereas the AMD embedded Ryzen R1600 CPU inside the DS923+ immediately hit 100% CPU Utilization and failed (taking longer to convert the file per second than an actual second!).

Next one, time for some 4K PLAYBACK! Now, it is worth highlighting that we ARE looking at quite high-end 4K media here, at 120Mbps – so the odds of you having much media in this format/scale is quite small. Still, 4K TVs and the affordability of 4K media is growing, so we need to test 4K, as well as scale it up for years to come. I wouldn’t normally recommend either of these NAS for 4K Plex use (recommending at least an Intel Pentium, i3 or higher generally), but here is how they performed:

Yep, both NAS devices failed. But again, remember that this is a 120Mbps file. Had we tested 4K at the bitrate of many of the 1080p files, it would have been better. We have some 4K dedicated Plex content coming soon on these NAS devices, so stay tuned!

Next we tested the same dense 120Mbps 4K files as before, but in the HEVC version. Again, due to the support of this compression level on each of these Synology NAS being limited, converting the file was needed by default. Here is how the DS423+ and DS923+ NAS performed.

Yep, thanks to the introduction of converting the 4K file being needed, the embedded graphics of the DS423+ CPU saved the day hugely and the result was that although it played (after a small delay) on the Intel-powered DS423+, the DS923+ and ADM Ryzen hit a wall very quickly.

Our final test was a 4K file in HEVC, much like the previous test. However this was a HENCH 200Mbps – a herculean task compared with all other tests in this article. Here is the DS423+ and DS923+ tackled the task.

Yep, once again, that Intel J4125 Celeron CPU and it’s integrated graphics was able to get the converting/encoding done on the fly and win here. The AMD embedded Ryzen R1600 COULD have off-line transcoded for sure, but when it came on on-the-fly conversions, it just lacked the right tools on board.

Synology DS423+ vs DS923+ NAS – Conclusion and Verdict

Comparing the DS423+ from 2023 and DS923+ from late 2022 did seem a little unfair at first, as ALOT can happen in 1.5 years (technology moves FAST!). However, in terms of supporting multimedia, if you are looking at these two NAS drives SPECIFICALLY for Plex Media Server and Multimedia use, the older generation device with its Intel embedded graphics CPU just wins the day over the Embedded Ryzen R1600 from AMD. But either of these NAS devices presents a decent-sized financial investment and I think most users need to think about using them for MORE than just multimedia. Synology has clearly done a lot of thinking in the two years between the release of the DS423+ and DS923+, deciding to change the latter into something more ‘business-y’. When the DS423+ first arrived, it did so to mixed responses (Still 1GbE, an Intel Celeron but an older revision) and it has pretty much always been in the top 5 NAS since its launch for most users in terms of price and ability. Those with longer memories will know that the Diskstation portfolio used to be largely dominated by very much this kind of hardware architecture (i.e a file transfer focused CPU, more memory scaling, optional 10GbE, etc) and rather than building off the design of the 4-Bay DS920+ that came before it, the DS923+ seems to scale itself against the DS1621+. DS1821+ and more in it’s shape and abilities. If you were already looking at Synology NAS systems that being a heavy emphasis on scaling their architecture notably down the line in efforts to remain future proof, the DS923+ is going to tick ALOT of boxes for you. Whereas if you were looking at a Synology NAS for home use, a Plex Media server, low client/user use and generally as more of a setup-and-forget solution, then the DS423+ will likely suit your needs better and will have the added benefit of a more palatable price point in 2022. How far Synology will extend the build logic of the DS923+ towards other solutions in the diskstation/rackstation portfolio still remains to be seen. Most business users will want to opt for the DS923+ though. Cheers for reading!
