QNAP TS-464 or the Synology DS423+ NAS Drive – Which Should You Buy?

Choosing Between the Synology DS423+ and QNAP TS-464 NAS is more than just about how you are spending your money at checkout! Making a move away from 3rd public cloud storage can be a big, BIG decision for some users. The ‘freemium’ and low cost monthly subscription to the likes of Google Drive and DropBox seems like a drop in the ocean, right up until you realise that over the years you have spent hundreds of pounds and you face the fact that you are going to need to consider moving that data onto something more long term and ‘in house’. For many users, this is their first encounter with two of the bigger brands in the world of NAS, Synology and QNAP and although at a glance they seem to provide the same kind of solution, even a brief second glance reveals that these two brands have very, very different ideas of where you should be spending your money. Synology is the sleek, apple-esc presented solution that promises a smooth and uncomplex experience, with an arguably more rigid and fixed architecture. Whereas QNAP is the more customizable and flexible in its hardware and software, but has a slightly higher learning curve and requires more time to configure perfectly. Both brands provide an excellent range of NAS solutions with each of the solutions in today’s comparison being quite similar in price, but what you are getting for your money, the range of software included, the scope of hardware that is available and how they translate to upgradable and scalability is incredibly different! So, today we are going to compare the Synology DS423+ NAS released in March 2023 (HEAVILY comparable to the 2020 gen DS920+) against the spring 2022 released QNAP TS-464 NAS.

Synology DS423+ vs QNAP TS-464 NAS – Design

The design of the QNAP TS-464 and Synology DS423+ are both very uniform to the brands, utilizing existing designs in their respective Home/Prosumer/SMB ranges. Both are 4-Bay desktop solutions that are designed to be deployed easily and pretty much anywhere. They are largely the same in physical volume, with the Synology DS423+ arriving the tiniest pinch larger, but both systems provide a similar level of storage on their four SATA and 2x NVMe M.2 SSD bays. The Synology has the more traditional shape of the lockable storage media bays being immediately visible, but finish this with an incredibly modernistic shape and matt surface design. The front of the system features a single USB backup port, as well as 5 LEDs for system/drive activity and those two M.2 SSD bays are located on the base of the system. The QNAP TS-464 NAS uses a more glossy and slightly coloured design by comparison (featuring a copper side panel), with the 4 drive bays of the system being covered by a slidable and lockable semi-translucent panel. The QNAP also featured the same LED/USB present, but there are more LEDs on the QNAP and the USB here is both a USB 3.2 Gen 2 Port (10Gb/s) and is accompanied by a one-touch copy button. This is one of the early examples of how things in the NAS market have moved forward in hardware but Synology has instead doubled down on their focus of it’s DSM software platform above all else. The QNAP TS-464 is certainly the more expensive NAS of the two, with the DS423+, despite being newer and having a different position in the brand’s portfolio (see the DS923+ to learn more), but the hardware you are getting for that price tag is notably different and will become a clear divide between these two. Because of the compact design, both systems need to factor in intelligent cooling, as they will likely be in operation 24×7. This is another clear area where the brands have gone in different directions here.

The ventilation on the Synology DS423+ is certainly more visible but in a much more ‘branded’ and slick way. The QNAP TS-464 features no front-facing ventilation, instead using two small areas of ventilation on the sides of the chassis and the base of the TS-464 featuring further ventilation under each of the storage bays. The Synology on the other hand has much more passive airflow, with each of the individual storage bays being surrounded by a slit of ventilation and the side panel of the DS423+ having the Synology logo featured as further ventilation. Higher-end Synology desktop models feature metal mesh panels inside these logos to capture dust, but this is less of a concern in the more compact and discreet DS423+. Overall, I would certainly say that the Synology DS423+ have more visible efforts to maintain system temperature than the QNAP TS-464 (which is a real surprise when you see how the hardware these two systems are sporting compares) but both maintain a good operation temperature.

QNAP TS-464 NAS	Synology DS423+ NAS

When you look at the rear of the TS-464 and DS423+ NAS, you see another big difference in how each system maintains their respective internal temperatures, with the QNAP featuring a single 120mm fan that covers the bulk of the internal hardware airflow path and the Synology featuring two 92mm fans that cover around 70% of the rear of the chassis. Of the two, I would say the QNAP TS-464 is the noisier in operation of the two (when populated with 4x 4TB WD Red HDDs) by the tiniest of margins, but it isn’t really till you entertain the idea of enterprise HDDs or drives larger than 10TB that you need to worry about ambient sound around these two systems. Both the DS423+ and TS-464 can have the rotations per minute (RPM) of their fans changed manually or left on automatic as the system changes the internal cooling to ensure maximum efficiency.

QNAP TS-464 NAS	Synology DS423+ NAS

Overall, the design of the Synology DS423+ is still the better-looking system of the two and although I personally really like the copper and glossy look of the QNAP TS-464 NAS, I know that the bulk of users will want to ‘set up and forget’ their NAS, so these aesthetic design choices are less important to them. Equally, although the QNAP fan has the potential to cool its respective system much more, I think the Synology features a better balance of active airflow and passive ventilation overall. The QNAP still wins pretty big on its inclusion of a USB 3.2 Gen 2 One Touch Copy button enabled port for faster and more manual backup options (as well as still allow automated and connection-triggered backups as the Synology), but overall on points, this round belongs to the Synology DS423+ NAS.

QNAP TS-464 versus Synology DS423+ NAS – Internal Hardware

This is an area where you really see how both brands focus their priorities on the solutions they offer, as well as how the components common to NAS have evolved in the 2 years between their respective releases. The Synology DS423+ arrives with a familiar architecture to it’s predecessor (the DS420+) and is a fairly tried and tested formula by the brand. Synology was the first company to introduce NVMe SSD storage bays into desktop NAS systems around 5 years ago (something that QNAP has only really been catching up on in the last 2 YEARS). Likewise, Synology has made a few very brand-specific decisions in their system architecture that this rather more proprietary brand is often keen to implement. For example, the default DDR4 memory inside (2666Mhz SODIMM) is actually soldered to the main internal board (4x 256MB Modules), with an additional empty memory slot to allow an additional 4GB Synology-branded memory module. As the DS423+ has a CPU that has a maximum 8GB of memory, this is an oddly artificial limitation that results in the DS420+ only allowing 6GB of max memory, an odd move that is perhaps done out of system PCI/Bandwidth, rather than any kind of manufacturer restriction. The QNAP features a newer gen CPU (as you would expect after the later release) and this CPU allows up to 16GB of memory (4GB in the default model) across two upgradable slots. Likewise, returning to those M.2 NVMe slots, both system feature 2 bays that can be used for SSD storage upgrades, although both the DS423+ and TS-464 support SSD caching (when a pool of SSDs is used to speed up data write/read in conjunction with the larger HDD RAID array), Synology ONLY RECENTLY allowed NVMe Storage Pools on their platform, whereas QNAP  has allowed NVMes as standalone storage pools, for app booting, running the OS from and even their own special internal tiering system known as QTier. This is the first of several key differences between the QNAP TS-464 and Synology DS423+ NAS that show the divide in hardware between these units.

Model	QNAP TS-464	Synology DS423+
Price	£559               $650              €675	£508               $549              €569
Storage Media Support	4x SATA, 2x m.2 NVMe 3×1 for Cache/Pools/QTier	4x SATA, 2x NVMe SSD Cache/Pool Bays
CPU Model	Intel N5105/N5095	Intel J4125
CPU Frequency & Cores	Quad-Core 2.0-2.9Ghz	Quad-Core 2.0-2.7Ghz
CPU Benchmark Score	CPU benchmark 4161	CPU benchmark 3006
Memory Default/Max	4-16GB SODIMM DDR4	2-6GB SODIMM DDR4 (4GB onboard)
PSU Power & Design	90W External PSU	100W External PSU
Physical Fans	1x 120m FAN	2x 92m FAN

Of course, the clearest difference that most PC builder-minded people are going to notice is the CPU. NAS systems are designed to be operational for days, weeks, months and even years at a time. Therefore, in order to maintain optimal performance, as well as lower power consumption and lessen the damage that long-term operation can inflict on a processor, the CPUs used in NAS are a great deal more modest. In the case of the Synology DS423+ and QNAP TS-464 NAS, they feature Intel Celeron processors, each featuring an embedded graphics component (allowing graphical operations, multimedia handling and visual data to be handled by a specialized area of the processor), quad-core architecture and a base level clock speed of 2.0Ghz that can be burst (turbo/increased when needed). However, the newer generation N5105/N5095 CPU in the QNAP is able to reach a higher overall clock speed and also is more efficient (i.e uses a little less hardware resources to get a task done than it would take on the J4125 typically, so, therefore, can do more tasks overall when the full CPU power is utilized). Indeed, CPUBenchmark rated the newer CPU 30%+ higher in it’s scoring than the J4125 (again, as you would expect for a CPU released more than a year later by Intel), so this processor means that more can be done on the QNAP (in like for like tasks) and also this CPU allows a greater range of hardware to be built into the system. CPUs are one of the largest quantifying factors of how a NAS is built and this is because they can only handle a certain amount of connected hardware (storage bays, ports, expansion slots, etc) when connected to a larger controller/motherboard. This is commonly referred to as the # of PCI lanes and the chipset used in the build of the system. Because this newer Intel N5105 / N5095 CPU has more lanes to use at once than the J4125, it allows the newer NAS drive to have more hardware.

Synology DS423+ NAS – Intel J4125 CPU

These additional CPU resources, as well as the increased maximum memory and flexibility of how the M.2 NVMe SSD slots can be used ultimately mean that in terms of internal hardware, the newer released QNAP TS-464 wins over the Synology DS423+ NAS. It is worth remembering that the M.2 NVMe SSD slots on the QNAP TS-464 are PCIe Gen 3 x1 (down to the Celeron CPU still not having anywhere near the scope in it’s flexibility that the likes of an Intel Core, Ryzen or Xeon might have) and will bottleneck at 1,000MB/s, but this is still better than nothing and there is still the lingering question of the Gen 2 slots on the DS423+ being 2×2 or 2×4 – which will potentially limit the M.2 NVMes on the DS423+ further still. So the QNAP still seems to have a better balance of NVMe SSD support in its architecture overall.

Synology DS423+ or QNAP TS-464 NAS – Ports & Connections

Now ports and connections on the Synology DS423+ and QNAP TS-464 NAS is an area that is INCREDIBLY diverse in it’s approach by either brand. Once again, the reasons clearly to do with the CPU choice and position on their respective brand portfolios, but also the brand’s own decisions in build architecture/priorities still massively continue to be a contributing factor here. The Synology DS423+ NAS certainly comes across as the weaker of the two here in its connectivity and although a lot of the QNAP’s advancements in connectivity could be described as ‘future upgrades and simply facilitating extras or addons’, it still manages to provide a greater deal of connectivity to the day 1 user than the Synology system here. The port(s) that almost certainly will be the one that jumps out immediately on each system is the network connections. The DS423+ NAS arrives with 2x 1GbE ports which, although allowing link aggregation to create 2GbE with a smart switch, was still a little underwhelming in 2023 when released and looking increasingly out of step with modern network tech in 2024 (as we had already started seeing 2.5GbE arriving at the same price as 1GbE with a number of client hardware devices in 2020). The newer QNAP TS-464 features 2x 2.5GbE (so 5GbE via link aggregation and a supported switch) which now that some ISPs and budget switch manufacturers are providing affordable 2.5GbE solutions, will be incredibly useful. Then the is the additional PCIe upgrade slot on the QNAP NAS that allows upgrades towards 10GbE, dual-port 10GbE cards and even combo cards to add 10G and further M.2  NVMe bays via a single card. Again, there ARE upgrades and not something in the baseline model, but you can not argue with the future-proofing available here. Additionally, the DS923+ NAS released in December 2022 had the option to upgrade to 10GbE – something hugely absent here in the eyes of many on this 4xSATA and 2xNVMe DS423+ NAS. There is simply no avoiding that the 2023 released DS423+ looks a little dated in 2024, in large part to those 1GbE ports are something of a limiting factor.

Model	QNAP TS-464	Synology DS423+
Network Ports	2x 2.5GbE	2x 1GbE
USB 3.2 Ports	2x USB 3.2 Gen 2 (10Gb)	2x USB 3.2 Gen 1 (5Gb)
USB 2.0 Ports	2x USB 2.0	0
HDMI Ports	1x HDMI 2.0 4K 60FPS	n/a
PCIe Upgrade Slots	PCIe Gen 3×2 Slot (2Gb/s)	n/a

After the network and PCIe differences that favour the TS-464, the distance between the 2023 and 2022 NAS hardware architecture here is further extended. The Synology DS423+ features a further USB 3.2 Gen 1 (5Gb/s) port, but LACKS the option to upgrade it’s storage down the line with an expansion (such as with the eSATA port on the DS920+ and DS923+ NAS supporting the DX517 official expansion). QNAP counters this on the TS-464 with the inclusion of another USB 3.2 Gen 2 (10Gb/s) port, as well as some (obviously less useful) USB 2.0 ports. These USB 2.0 Ports are primarily designed to be used in conjunction with the optional visual output (HDMI 2.0 4k 60FPS) on the QNAP as a KVM (Keyboard, video and mouse) setup with the included parallel HD Station application and its tool. The HDMI and direct interface of the QNAP is still pretty niche as a service on this system, but it has a number of useful multimedia, surveillance and VM utilities that can be quite impressive. Expansions on the TS-464 are more diverse than the 5-Bay DX517 on the DS423+ (which again, is NOT supported anyway), with QNAP offering 2, 4, 6, 8 and 12-Bay expansion chassis (arriving in JBOD or hardware RAID enabled) that connect over USB or an inclusive PCIe card. Overall, it comes as no surprise that in terms of hardware, the QNAP TS-464 still takes the first place, as the Synology DS423+ (like most of the brand’s solutions) is prioritizes the DSM platform and it’s tools/services over the hardware. Let’s discuss the software on each of these brands.

QNAP TS-464 or the Synology DS423+ NAS – Software

When you are choosing to buy a Synology or QNAP NAS, it is always worth bearing in mind that you are not just buying a bunch of hardware, but you are actually getting a fully-featured software solution. Both the Synology DS423+ and QNAP TS-464 arrive with each brand’s premium NAS software and services platform, DSM and QTS respectively. Both of these platforms include a traditional operating system level of accessibility and control, that can be accessed via pretty much any web browser or desktop OS, as well as numerous tailored mobile client applications. The Synology DSM platform is a lot more comparable in design and control with Mac OSX and is by far the more user-friendly option of the two. The QNAP QTS platform is a lot more comparable to Android in its initial GUI and then more like Windows in it’s navigation, arriving as the option with a greater deal of configuration and control, but with a steeper learning curve. Another big difference between QTS and DSM is how they present their services, with QNAP providing a larger degree of support of 3rd party applications (both in the app center and in the configuration of their own range of 1st party applications. Synology DSM on the other hand proves a larger and more impressive range of fist party tools that are designed to replace/improve upon the 3rd party tools you might be using, with many of it’s applications being comparable to top tier 3rd party paid tools in the market (the Synology collaboration suite, the Surveillance Station application and pretty much everything in Synology Drive, just as a start). The QNAP platform also, in it’s efforts to be as widely compatible and configurable as possible, occasionally stems into over-complexity and risks the user tripping over itself as it tries to manage the larger scale of configuration Whereas, although the Synology DSM platform may seem a pinch more closed and fixed, it manages to prevent the users from accidentally ruining their own storage system. Here is a full breakdown of the key applications that are included with the QNAP TS-464 and Synology DS423+, broken down into categories:

	QNAP TS-464	Synology DS423+

	2 Step Authentication	Access Protection and Allow/Deny list
	Firewall App	Synology Secure SignIn
	Access Protection and Allow/Deny list	Synology C2 Password

As you can see, both NAS brands provide similar levels of software, services and features, but they are presented in very different ways. Once again, I cannot emphasise enough how much more the QNAP platform is configurable but ALSO how it can often give you too much configuration and risk overwhelming less experienced users. The Synology DSM platform, for all its comparative rigidicy, is still overall the better software experience and you definitely see that Software over hardware priority from the brand clearly here. I have made long, LONG reviews on each of the NAS brand’s and their software platforms, which you can watch below for much, much more information on their respective strengths and weaknesses.

QNAP QTS 5.0 Review	Synology DSM 7 Review

Ultimately, it will come as no surprise that Synology come out on top in terms of software compared with the QNAP. That is not to say that the QNAP QTS platform is not good, it really, really is and some of the applications that are included for home and business users are often genuinely impressive, unique and provide facilities to the end-user that are wholly unavailable on any other NAS platform (eg Multimedia Console as a single portal media manager, the 2-3 Click VM storages and repository that are available in Virtualization Station, Linux Station and Container Staton or the QuMagie AI-powered tool that is able to cover a greater range of subjects and categories that any other NAS photo tool out there). However, the QNAP QTS platform is not quite as polished, as user-friendly and as responsive as the Synology DSM platform overall. If you want a better idea how these two NAS software platforms compare directly (i.e face to face), then you can check out my DSM vs QTS video below:

Alternatively, if you are NOT interested in using the software included with your NAS, there is always the option to install TrueNAS – Something that is surprisingly easy on the QNAP NAS (see video below):

QNAP TS-464 or the Synology DS423+ NAS – Conclusion

Ultimately, choosing between the Synology DS423+ and QNAP TS-464 largely comes down to a question of hardware vs software. The QNAP TS-464 is by a long distance the more advanced in hardware in practically every way (thanks of course to the brand’s focus in this direction) which leads to that system having a tremendously large scope in terms of what you can do with it, how far the storage can be expanded and how upgradable the system can be. The QNAP is the better future-proof hardware choice and despite the Synology NAS platform having a stronger software platform, it still has a vast array of software and services available in QTS nonetheless. For those that are hardware-focused or want a NAS to support their existing 3rd party client tools and apps, the QNAP TS-464 is by and larger the better choice. The Synology DS423+ NAS on the other hand, despite its 2-3 year older hardware (already premiered in the 2020 released DS920+) and arguably safer/sensible stance on hardware in general, is still a great NAS that will likely becoming more popular and palatable in the 4-Bay NAS market as the pricing becomes a bit more flexible (as many will still weigh the DS423+ with the older DS920+ that still has stock floating around and opt for the latter). Add to that the core strength and first-party focus of DSM leading to this hardware+software solution providing you with a huge array of polished and premium feeling tools at your disposal. As long as you are happy to do things ‘Synology’s way’ and are looking for an easy to use system that will not tax the end-users brain, you will find Synology the better software choice overall.

Synology DS423+ vs DS923+ NAS – Which Should You Buy

Buying your first network-attached storage device can be really intimidating! If you have spent the better part of a decade storing your personal or business data on public cloud services or in a drawer full of USB drives, but have now taken the grown-up decision to go ahead and migrate over to your own private network-attached storage (NAS). You might have done this for reasons of cost, centralization or perhaps for security, whatever the reason for your data migration, there is simply no denying that the world of NAS can be a fraction complex and confusing early doors. Like any kind of modern computer appliance, you want to make sure you buy right the first time and when it comes to choosing between two of the latest generations of Synology NAS devices, these two incredibly similar four-bay devices might be two of the most different solutions I have ever compared. The Synology DS423+ is a home and small business-focused compact NAS designed to leverage an affordable price point between reasonable hardware and reasonable software and abilities. The slightly older Synology DS923+ (by 6+ months), on the other hand, has much of a high and even in some places entry enterprise-level focus about its architecture and is needless to say the more expensive of the two. Nevertheless, both of these Synology NAS devices can be picked up for around $450 to $600 (without drives), the contrast between their pricing, are actually very different beasts. Therefore, for users that don’t quite know their AMD embedded from their Celeron integrated processors, or who aren’t sure of the benefits that ECC can bring, today I want to compare the Synology DS423+ and Synology DS923+ and help you decide which one best deserves your data!

Just before we get into the meat and potatoes of this comparison, it is worth highlighting that regardless of whether you buy the Synology DS923+ or DS423+, you are guaranteed to get a system that can perform all of the following:

• Both units feature x86 processors, which allow a wide degree of app/services to run well and are a good price vs hardware balance
• Both the DS923+ and DS423+ are constructed of plastic desktop compact chassis, thereby reducing power consumption, noise and heat generated
• Both can Stream 1080p HD or 4K media, with superior performance natively and mid-range performance in Plex
• Both the Synology DS923+ and DS423+ NAS support AI-supported photo and ‘thing’ recognition supported to a very high degree from the free branded software included
• For Business users who currently enjoy the use of Google Workspace or Office 365, both of these NAS provide excellent means to backup your mass cloud accounts (as well as natively sync, dupe and configure rules on the fly)
• Both the DS423+ NAS and DS923+ NAS support snapshots, for more incremental and version protecting failsafe in efforts to protect you from Malware and Ransomware attacks, by allowing multi-versioning storage history to browse through and restore
• Both units are DLNA certified so can be accessed, browsed and played from by popular DLNA devices, such as Amazon Firestick, Alexa, Google Home Chromecast, Apple TV, Bose, Sonos, iPads, etc, as well as connectivity between these platforms with IFTTT
• Both are multi-bay, RAID enabled devices NAS devices that support JBOD, RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10 (as well as Synology Hybrid RAID too for their Plus series range), though it is worth highlighting the DS923+ is the only one that supports an expansion and therefore also can support RAID 5, RAID 6, RAID 10 and SHR-2 over an expansion (more on that later)
• Both devices run on their own proprietary operating system that can be accessed remotely or locally. These include regular updates to the firmware, security patches, applications and more. Ranging from multimedia, home and multi-tiered backup applications, to more business end tools such as Surveillance software, Virtual Machine deployment and business-class backup and synchronization tools.
• Both the DS423+ and DS923+ use and can be accessed equally by a multitude of mobile applications such as DS File, DS Video, DS Photo, DSCam and DS Music that are created by and constantly improved by Synology.
• Both NAS are completely compatible with Windows, Android and Mac systems, as well as acting as a bring between software platforms to share and distribute files for migration and file sync]
• Both units can be used as a mail and/or business servers, providing excellent 3rd party CRM and first-party CMS systems, as well as the fantastic Synology collaboration Suite of applications Chat, Drive, Mail, Calendar, Office and Active Backup Suite
• Both systems will support DSM 7.1 or DSM 7.2 out the box, as well as support software updates (security and feature) for many years moving forward
• Both systems support the Synology Surveillance Station applications, support numerous cameras and arrive with 2 camera licenses with your purchase

But you didn’t come to this comparison page to find out what they had in common, you wanted to know what makes them different and which one best suits your needs, so let’s crack on with this comparison.

Synology DS423+ vs DS923+ NAS – Price and Value

Now, for those of you that are keeping a very close eye on the budget, it will already be clear to you that the Synology DS423+ is the lower-priced NAS of the two, by quite a considerable margin! Arriving, depending on where you are in the world, for around $449 to $499, it will immediately look more appealing to those on a tight budget when compared against the $549 to $599 of the DS923+. And that is before you’ve gone ahead and purchased any storage media too, so that’s saving of $100 to $150 could go a long way to further bolstering your network-attached storage setup. So, if the most important thing to you right now is remaining within a tight budget, then it might be worth seeing to read the rest of this article as when comparing DS423+ and DS923+, we have to look considerably more at the subject of value, not price. Price. Both of these devices arrive with the same software, Synology DSM 7.2, as well as both systems being two drive NAS solutions that support nearly identical ranges of storage media too, but more on that later. In terms of physical size, the range of components, they are pretty darn similar at a casual glance. However, it is in terms of the individual hardware components and scalability where the Synology DS923+ shows its worth, which we will cover shortly in the hardware section. But at least in terms of numerical value, the Synology DS423+ carries the lead. However, the reality isn’t quite that simple:

This is because the Synology DS923+ was released approx than half a year earlier than the DS423+ (Nov 2022 vs April 2023) and because of its wider availability and longer presence in the market, it has been featured in numerous special offers throughout that time. We saw this near $500 NAS on a few considerably impressive special offers throughout Amazon Prime day and other smaller eShop-specific events. So, yes, the DS423+ is the lower-priced NAS of the two, but do make a point of checking your local online retailer to see if the DS923+ is on special offer right now!

Synology DS423+ vs DS923+ NAS – Hardware and Connections

The hardware architecture of the DS423+ and DS923+ clearly have two very different target audiences in mind. The DS423+ has more of a home and multimedia feel about it, while the DS923+ feels substantially more like a business solution. This is reflected in numerous areas such as the distinct differences in CPU, memory specifications, and potential for growth. Even if you were to take into account the affordability of the DS423+, it has to be said that in the majority of hardware available, the DS923+ is significantly more powerful and scalable in practically every way. Here is a brief summary of the key hardware highlights of either system, side-by-side:

So first and foremost, we need to discuss the main differences between the CPUs available here. The Intel Celeron found inside the DS423+ is a four-core, four-thread processor with a clock speed of 2.0 GHz that can be burst to 2.7 GHz when needed. However, despite the age of this CPU, which was released towards the end of 2019, it is the integrated graphics of this processor that gives it a slight edge for some users in terms of NAS deployment- especially those looking at multimedia use for their system. For users that are looking at the manipulation of graphical data, or more commonly are using the NAS as a multimedia server and wish to convert dense multimedia into something more manageable locally (for example, converting a dense 4K file into a much smaller and portable version to watch on the phone whilst commuting to work, on the fly), integrated graphics allow the NAS to perform this task with much lower overall resource consumption.

Thanks to it having a more specialized tool to get this job done. The embedded Ryzen R1600 processor on the other hand, lacks the integrated graphics and is a dual-core processor instead of a quad-core. However, it substantially makes up for this by being a much more powerful dual-core processor, with four threads that allow the system to assign system resources in a similar way to that of having multiple cores. Equally, the clock speed is noticeably higher here with the DS923+ CPU having a 2.6 GHz base power that can be burst when needed to 3.1 GHz. It is true that in cases of graphical manipulation or multimedia conversion, the AMD CPU here will be far less efficient and capable. However, in practically every other way, it is superior to that of the J4125 inside the DS423+. And if you are more concerned with traditional file transfer speeds internally and externally, the DS923+ will comfortably be the better-performing NAS.

 

The CPU choices in the DS423+ and DS923+ also result in very different memory architectures in each device, which will undoubtedly result in different scalability in the long term. The DS423+ arrives with 2GB of 2666Mhz memory, soldered to the main controller board, which can be further expanded via an available SODIMM memory slot to 6 GB total. This may be a little disheartening when you find out that the CPU here is actually capable of supporting 8 GB maximum memory. However, due to that initial 2GB memory being fixed internally, you cannot officially exceed 6 GB physically. This shortfall is considerably magnified when you bring into comparison the DS723’s memory structure. It arrives with 4GB of DDR4 3200Mhz memory which can be expanded to a whopping 32 GB total across two available SODIMM slots. Additionally, the system arrives with error-correcting code (ECC) memory, which ensures that data that passes through the memory during write operations will have its integrity checked by a separate module on the memory of the system. If any irregularities or inconsistencies are spotted, that data will be repaired. This goes a long way to reassure any doubts around the integrity of long-term archival data and susceptibility to things like bit rot. This is one of the main reasons why the DS923+ is considered much more of a business solution overall.

Much like the memory choices by Synology in these two NAS devices, the ports and connections of them both are similar, but one is definitely more scalable than the other. Both systems arrive with standard gigabit ethernet connectivity, with two available ports that each will provide up to a maximum 109 megabytes per second. Both systems also arrive with USB 3 connectivity, but it is only 5GB gen 1 USB. However, it is from here onward that the DS723 massively upscales things:

Power consumption	28.3 W (access) 8.45 W (disk hibernation)	35.51 W (access) 11.52 W (disk hibernation)

For a start, the DS923+ features an eSATA external port that is used to connect the official Synology 5-bay expansion device, the DX517. This means that while the DS423+ has a maximum long-term capacity of four SATA drives, the DS923+ allows you to expand your storage down the line by an additional five SATA bays (so 9 Bays total). This can be done gradually and this storage can either mirror the original NAS or extend the storage pool across both devices.

Scalability and expandability do not stop there though, with the DS923+ also having the option to add a network adapter upgrade module (the E10G22-T1-MINI) to increase your network bandwidth to 10GbE. This is going to be incredibly useful for users who plan on taking advantage of SSDs or plan on having a much busier network environment between the NAS and multiple users and tasks at any given time. And it doesn’t stop there! Though BOTH systems also features two SSD bays on its base for installing M.2 2280 SSD modules (which can be used for caching or as raw storage pools, depending on which drive you use), the DS423+ is a Gen 2 PCIe lane system, whilst the DS923+ is a Gen 3 system – resulting in double the bandwidth per lane (ultimately, the difference between 500MB/s max per SSD on the DS423+ and 1,000MB/s on the DS923+). This is a feature that, although growing more common across Synology’s NAS portfolio, it is still unavailable on many of their lower tier/affordable systems (such as the DS224+) and, alongside the lack of storage expansion support, the gen2 speeds on these bays will place limits the storage potential long term on the more affordable NAS.

Finally, we need to discuss storage media compatibility, as this has grown to be another thing that has changed the way in which a user can populate their NAS quite a lot in recent years. On the list of storage media that they are prepared to verify as compatible with their systems. Although technically, one could say that any SATA media drive would be compatible with a SATA NAS, there are still a few incredibly isolated examples of compatibility, durability and stability. Synology requires that all drives need to be officially checked and verified before they’re prepared to add them to their list in order to truly guarantee that a user will get the promised Synology experience from their hardware with that media. As questionable as this might sound, the result is that the list of compatible storage media for both of these devices, despite their incredible similarities, is actually pretty darn different. Take a closer look at the slideshow below of compatible HDDs from WD and Seagate on these two NAS systems (from 21st July 2023) and see if you can spot an odd inconsistency:

In the case of the DS423+, we see a smaller pool of supported storage media, as well as a lower list of larger capacity drives being featured also. The DS923+, on the other hand, seemingly has a larger pool of more high capacity drives added and available to it, as well as a larger range of Synology’s own drives available for use with that system that includes the higher end options in the HAT5300 range. Synology has clearly prioritized higher-end drives for more advanced Synology systems, but for those that like to use their system clearly and rigidly within the defined parameters of a brand to maintain their warranty/guarantee, this is going to be a little disheartening to see the smaller pool of verified compatible storage media on the more affordable NAS solution. This is something that may well change over time as more drives are added to verified compatibility lists, but Synology has not exactly been putting their foot on the gas here. Given how close these two systems have been released side by side and the large disparity between their compatibility lists, I can’t see a huge amount of change happening anytime soon. It is absolutely no surprise that the more expensive Synology NAS has a better degree of hardware options in the long term. Though, it should be highlighted that a lot of the real benefits available in the DS723 are optional extras, long-term scalability and upgrades that are not necessarily available in the default model. It could be very easily argued that you are paying for entry to then pay extra for delivering upgrades, SSD upgrades, storage scalability, and increasing your memory years from now. Nevertheless, the fact that the baseline memory is ECC and the AMD CPU is indeed more powerful in most ways, does make up some of that additional cost and ultimately mean that in terms of hardware and connectivity, the DS923+ is the better of the two.

Synology DS423+ vs DS923+ NAS – Software and Services

At the risk of being incredibly repetitious, both of these devices are remarkably similar in what they can do in Synology’s premium DSM software platform, but the scalability and scope provided by the DS923+ inevitably leads to that more expensive system, ultimately giving you just more resources with which DSM can utilize. In terms of the actual range of applications, services supported on either system and scope for use right out of the box, both the DS423+ and DS923+ have got more than enough to run every single available app and tool available in DSM 7.2. Despite their rather modest scale, both systems can run multiple virtual machines, host a fantastically capable surveillance solution with numerous cameras, both can provide an excellent Plex media server experience (with a slight edge to the DS423+ in terms of conversions and transcoding when needed), and in terms of backups, both systems support the full range of services from Hyper Backup and Active Backup Suite. If you are a small business or just a small group of users who are going to be interacting with either of these NAS units fairly regularly, you’re going to have a largely identical experience in either one of these two systems using the baseline default hardware. However, things will change as soon as you start moving into larger simultaneous access, more high-volume application exchanges between the system and client hardware, and the scope of each one of those individual processes growing over time. In terms of the escalation of accessing the services of DSM and long-term future-proofing of a system running at top speed, despite growing requirements and demands of the system, the DS923+ comfortably wins.

Notwithstanding that the system has a much higher clock speed CPU that, despite only being a dual-core processor, features a four thread architecture with DSM, allowing a lot of the spreading of resources normally associated with cores to be made available with vCPU allocation (containers, virtual machines and just natively). Then there is the scope for the larger overall capacity available to be upgraded towards in terms of memory, with the rather modest 6GB of memory on the DS423+ looking quite underwhelming when compared against the whopping 32 GB maximum memory that is scalable on the DS923+. That ultimately adds up to the more expensive NAS system having a better opportunity to grow alongside a more demanding data storage network of connected devices and users over time. And we haven’t even touched on the performance benefit in DSM and all of the first and third party applications when we factor in support of Gen3 SSDs for caching or storage pools in the DS923+, both of which are going to allow much better, long-term utilization and overall, a much smoother experience for a considerably longer amount of time than that of the DS423+. Ultimately, if you think your utilization of the NAS is going to grow steadily and increasingly over time, the DS923+ is the better choice here in terms of software, in and out of DSM.

Synology DS423+ vs DS923+ NAS – Conclusion and Verdict

Unsurprisingly, what we have here is an old-fashioned case of getting what you pay for. The DS423+ is a very solid, and reliable NAS solution and is definitely more than capable of running the bulk of modern NAS hardware needs, also, remaining pretty flexible in the resources available to it on day one to get the job done. Equally, for home users and particularly those seeking a more flexible approach to multimedia, the DS423+ does bring a decent amount of bang for buck when you compare it against the bulk of other Synology solutions in the brand’s portfolio. But it just pales in comparison to the sheer scope of scalability, upgrade options and flexibility long-term that the DS923+ provides. And regardless of whether you’re a business user or a home user that may perhaps be looking to do something more aggressive with their storage down the line, the DS923+ justifies a lot of the extra expense, simply by the weight of it having that ECC memory, twice the default memory on day 1, Gen3 SSD NVMe storage options, expandability, 10G as an optional extra and the scale of how far you can upgrade the memory. As mentioned earlier, we have to at least acknowledge that a lot of these advantages that the DS923+ presents compared with the DS423+ are ones that you will only really take advantage of if you spend a little bit more money, but having the option for that scalability down the line for many users is going to be worth the investment on day one. Side by side, in most cases, the DS923+ will comfortably outperform the DS423+ even in the default model, so you still aren’t losing out just because you’re paying extra for upgrade options you may not use later down the line.
