An Easy Guide to Buying the Right UPS for your NAS System

The popularity of uninterruptible power supplies (UPS) has risen significantly in recent years. Not just for businesses, but for home users as well, who often have limited power setups such as houseboats, pop-up offices, and mobile homes. The value of having a safety net for your power-consuming devices is undeniable. Additionally, for those whose data is critical and whose business or personal life relies on constant access and read/write operations, a UPS can provide peace of mind. In the past, power failure solutions were only accessible to large enterprises and high-level businesses, with prices starting in the five figures. However, with the rise of network-attached storage (NAS) in homes and the increased efficiency of mass production techniques, owning a UPS device to protect data in both homes and businesses has become more affordable. However, choosing the right UPS for your NAS device, such as a QNAP or Synology, and finding one that fits within your budget can be challenging. In this guide, we will address the three commonly asked questions by users considering a UPS but unsure of which device to choose: 1) How does a UPS work and how will I benefit? 2) How do I determine the right Watts, Volts, and Amps to choose the best UPS? 3) How much will a UPS cost? We hope this guide is helpful for NAS buyers looking at brands such as Synology, QNAP, Asustor, Terramaster, and others, and also for anyone looking to choose the right UPS for other devices.

What Are the Factors I need to consider when buying a UPS for my NAS?

Choosing the right UPS (uninterruptible power supply) for your Synology or QNAP NAS (network-attached storage) can be a complex task, as there are many factors to consider. However, by following a few key guidelines, you can ensure that your NAS is protected against power outages and other issues that could cause data loss or corruption. The first thing to consider when choosing a UPS for your NAS is the amount of power that your NAS requires. Desktop NAS devices with external PSUs typically have a power consumption of around 60-120 watts and rackmounts generally 250W and above, although this can vary depending on the specific model and the number of hard drives that are installed. It is important to choose a UPS that can provide at least this much power, as well as a bit extra to account for any other devices that may be connected to the NAS. Another important factor to consider is the runtime of the UPS. This is the amount of time that the UPS can keep your NAS running in the event of a power outage. The runtime of a UPS is typically measured in minutes, and you should choose a UPS that has a runtime that is long enough to allow you to properly shut down your NAS in the event of a power outage.

Another important feature to look for when choosing a UPS is the ability to communicate with the NAS. Some UPS’ have built-in USB or serial ports that allow them to communicate with the NAS and provide status information. This can be very useful in case of power outage, as it can allow you to monitor the status of the UPS and take appropriate action. Finally, you should also consider the size and weight of the UPS, as well as its overall design. A UPS that is smaller and lighter may be more convenient to deploy, but you should also make sure that it is well-designed and built to last. When choosing a UPS for your NAS, it is important to consider the amount of power that your NAS requires, the runtime of the UPS, the ability to communicate with the NAS, compatibility and the size and weight of the UPS. By following these guidelines, you can ensure that your NAS is protected against power outages and other issues that could cause data loss or corruption.

What is a UPS and Why Should I Buy One for my NAS?

The most frequently asked question about UPS is typically “What exactly is a UPS and what does it do?” UPS stands for Uninterruptible Power Supply and many users believe that purchasing a UPS means they can run their devices and access data from their NAS, DAS, or SAN for hours after a power failure. While this is technically true, it would require a significant financial investment in the form of a 5-figure sum. In reality, most users do not require hours of protection for their read/write data operations on HDD media. Instead, what is often needed is enough time to safely shut down the server or RAID storage. This can be achieved by spending only hundreds of pounds, not thousands, as it depends on the number of devices drawing power, their specific needs, and the efficiency of the chosen UPS. For more information on UPS and how to choose one, please watch the video below.

How Does a UPS Draw Power and How Do I Connect My Devices?

This topic can be challenging for some, so we will break it down and explain it in a simple way. Before delving into technical terms like Watts, Volts, and Power, let’s use an analogy that’s easy to understand. Imagine receiving electricity to your device as drawing water from a tap.

 

To understand this concept, we can use an analogy of a tap and water. Just like a tap needs water and pressure to deliver it through the pipe, an electrical circuit needs electrons and voltage to deliver electricity to a device. The water represents the electrons that carry electricity from the power source to the destination device, like a NAS, DAS, or PC. The tap represents the destination device and the water/electrons are going around in a circuit back to the water/power source, which is mostly unseen in the cables.

The pressure in the analogy represents the VOLTAGE, which is the strength of the electricity being pushed by the electrons in the circuit. It’s important to measure this as some devices are designed to only accept a specific amount of voltage. If the voltage is too high or too low, the device will not function correctly.

AMPS represent the amount of electrical charge that passes a given point in a second, similar to how much water passes through the pipe per second.

So, now we need to know the WATTS of the device. This is compiled with the following equation:

 

AMPS x VOLTS = WATTS

or

Water Volume x Water Pressure = Water Power

If you’ve ever experienced weak water pressure in a shower while living in an apartment on a higher floor, this is likely due to the water pressure not being strong enough to deliver the water to the destination device. Similarly, a smaller battery pack is often measured in milliampere-hours (mAh), which represents the amount of charge available, rather than time. Using the analogy of water, this would be like a large drum of water. The amount of water and how fast it travels from the drum is not as important as the available water that can be carried over to the tap. The output and result is heavily affected by the AMPS and VOLTS, similar to the pressure of water and the maximum or minimum amount of water the tap can receive.

Choosing the right UPS Battery for your Home or Office

The majority of UPS devices have a similar setup. You connect one end to your main power outlet (3 Pin, 2 Pin, etc) and the UPS has multiple ports for connecting your destination devices (PC, NAS, etc). Inside the UPS chassis, there is one or more batteries that are charged from the wall plug, while your devices are powered directly from the wall and not drawing from the batteries unless there is a power failure. In the event of a power failure in your home or business, the destination devices will switch to drawing power from the batteries, giving you time to save your data and shut down your devices safely, protecting your digital storage from corruption or loss. It’s worth noting that when buying a UPS, there are many figures to consider, but the power drawn by computing equipment is typically measured in Watts or Volt-Amps(VA).

BUT

The power in Watts is the real power drawn by the equipment.Volt-Amps are called the “apparent power” and are the product of the voltage applied to the equipment times the current drawn by the equipment.

Inexpensive UPS devices typically have a shorter running time because they don’t provide as much charge. Mid-range UPS devices, on the other hand, offer longer charge times, more features, and additional functionality such as network alerts, internet alerts via SMS or email, an LCD display, USB connectivity for maintenance, and the ability to automatically save or shut down certain NAS or PC machines in the event of a power failure, eliminating the need for manual intervention.

There is more to choosing the right UPS than matching the WATTS of your destination device and that of the UPS

UPS capacities are giving in VOLT-AMPS , not WATTS

Remember again,

VOLTS x AMPS = WATTS

Well, Resistance present in electrical load means that the WATTS cannot be matched Like for Like. So:

How do I Choose the Correct VA for the Watts on my NAS, PC and more?

You will need to consider a UPS with a VOLT-AMP 50-70% higher than the WATTS present on your destination device. Don’t forget to factor into your consumption any other devices that are drawing from the UPS, as this consumption is not per device, but TOTAL.

What is Line Interaction on a UPS?

Some UPS devices have a “Line Interactive” feature that can strengthen a weak or inconsistent power supply, particularly useful for those in remote areas where maintenance may be less frequent. When it comes to sizing a UPS, it’s important to note that equipment nameplate ratings are often in VA which can make it difficult to determine the Watt rating. To avoid oversizing the UPS, it’s recommended to configure the system such that the VA rating of the load is no greater than 60% of the UPS VA rating. This will prevent exceeding the Watt rating of the UPS. However, this approach may result in an oversized UPS and a longer run time than expected.

– Battery Packs, Listed in VOLTS and can be added to an existing UPS

– Replacement Battery Cartridges, an Internal Upgrade, RANGE specific

– Available in Desktop or Rack mount

How Do Synology, QNAP, Asustor and Terramaster NAS work with a UPS?

Almost all NAS drive brands support the use of a smart UPS, connected via USB for monitoring or via the network. That said, how each NAS system reacts to a power cut and switching to the UPS battery does differ. I recently tested the CyberPower 1500 system with a selection of 4-Bay UPS systems to see how each NAS brand’s hardware and software react. Below is the video for each brand. Just click the video, or you can open them up in a separate tab by clicking the title.

How Long do UPS Batteries Last?

The lifespan of a UPS (uninterruptible power supply) battery can vary depending on several factors, including the type of battery, the quality of the battery, the usage, and the environment in which the UPS is used. However, on average, a UPS battery should last between 3-5 years with proper usage and maintenance. Lead-acid batteries, which are commonly used in UPS systems, have a typical lifespan of 3-5 years. However, this lifespan can be shortened or extended depending on the usage and maintenance of the battery. For example, if the battery is frequently discharged to a low level, this can shorten its lifespan, whereas proper charging and maintenance can prolong it.

It’s important to note that the lifespan of UPS batteries can also be affected by environmental factors such as temperature, humidity and the amount of use. High temperatures and humidity can shorten the battery life, while keeping the UPS in a cool and dry environment can extend it. It’s also worth noting that most of the UPS batteries have an end-of-life indicator, which will alert you when the battery is no longer performing as well as it should. This will give you an idea of when the battery needs to be replaced.

In conclusion, the lifespan of a UPS battery can vary depending on several factors, including the type of battery, the quality of the battery, the usage, and the environment in which the UPS is used. On average, a UPS battery should last between 3-5 years with proper usage and maintenance. Keeping an eye on the end-of-life indicator and maintaining the battery in a cool and dry environment can help to extend the battery’s lifespan.

Samsung 990 EVO Gen 5 SSD Review

It would be fair to say that of all the brands that exist in the SSD consumer and commercial market, few have the recognition and long-running reputation that Samsung has. A mainstay in consumer day-to-day devices, they have also been long-running pioneers in the world of solid-state storage for years now (first truly cutting their teeth in consumer M.2 NVMe SSD storage with the hugely popular Samsung 960). In the previously established PCIe Gen 4 generation of M.2 NVMe SSDs, Samsung (along with WD) in late 2020 were the very first brands to introduce 7GB/s (7000MB/s) performing drives to the market, massively overshadowing competitors such as Seagate and ultimately giving them a huge advantage, one that has been enjoyed for almost 3-4 years. Fast forward to now and the Gen 5 tier of M.2 NVMe SSDs has established itself, and despite hugely confident releases from Phison-equipped drives with Seagate, Sabrent, TeamGroup, and more that have been promising 10, 12, and 14GB/s, Samsung has been oddly silent on the consumer Gen 5 tier… Until now! The release of the Samsung 990 EVO marks the brand’s first release into an almost guaranteed large range of Gen 5 solutions in 2024/2025, but with a rather niche approach to its hardware design choices, a shift of focus on its ideal deployment, and performance numbers that seem comparatively lower to many drives on the market – is the Samsung EVO 990 SSD a rather bizarre first Gen 5 entry by the brand? Let’s review the Samsung 990 EVO SSD, discuss what makes it different from the usual crowd, benchmark it, and ultimately decide if it deserves your money and your data!

Samsung 990 EVO Gen 5 SSD Review – Quick Conclusion

The Samsung 990 EVO is a unique drive, ideal for systems with limited PCIe allocation and concerns about heat and power usage. While Samsung’s strategy aims to meet future trends, there are questions about PCIe Gen 5 bandwidth utilization and performance sustainability in modern PC architecture. The 990 EVO, being Samsung’s first DRAMless consumer Gen 5 SSD, offers a decent balance of performance and efficiency in compact systems, but its position in the market might be overshadowed by competitors’ higher-spec Gen 5×4 drives. It’s an acceptable choice for those seeking an OS drive or a base SSD for micro/compact systems, offering good durability and power efficiency. However, gamers and power users might find it lacking compared to more robust options available. The Samsung 990 EVO stands out in its niche but faces stiff competition in the broader SSD market.

Samsung 990 EVO Gen 5 SSD Review – Retail Packaging

The Samsung 990 EVO arrives in fairly standard packaging from the brand and is arguably fairly understated and regular stuff. The drive arrives without any kind of heatsink (more on that later), but comes with the M.2 NVMe SSD in a plastic shell, alongside brief information on installation, the Samsung Magician software, and details on the 5-year inclusive warranty. The retail box itself is adorned with all the usual tech spec information and, although it’s all a bit ‘meh’, at the very least still carries that Samsung charm.

The drive arrives with a base panel heatshield that arrives pre-applied on the base panel of the SSD (on the bare PCB side), and it is located under the storage NAND. It’s a little odd that this isn’t located on the top, but I am sure Samsung has done enough R&D to know this makes more sense.

The top of the drive has a simple adhesive label with all the relevant drive information, but this is not any kind of metallic heatshield.

Peeling this back reveals an unusual arrangement of components on the PCB (on both the 1TB and 2TB version), at least compared with the bulk of both Gen4 and Gen5 SSDs in the market. Let’s discuss the hardware that the Samsung 990 EVO runs on.

Samsung 990 EVO Gen 5 SSD Review – Hardware Design

As mentioned above, the Samsung 990 EVO is a different kind of drive in the market. But this is especially unusual when you see that Samsung is attempting to straddle both the Gen4 and Gen5 market with this drive. Advertised as a Gen 5 M.2 NVMe, its architecture and the bandwidth afforded to it are very unconventional (at least by 2023/2024 Gen5 standards, but this could change in the near future – something Samsung is likely banking on with this drive).

The 1TB and 2TB versions of the Samsung 990 EVO are largely the same (barring the capacity, of course) and are built using all ‘in-house’ proprietary components – much like most other Samsung SSDs. Much like one of their biggest SSD rivals, Western Digital, Samsung likes to keep the development and onboard parts limited to 1st party design (or at the very least using subsidiaries). This can often mean that Samsung runs its own race when it comes to rolling out consumer and commercial storage drives – as they cannot overly rely on the likes of Phison for an SSD controller, MICRON for storage NAND, or SK Hynix for DRAM. The Samsung 990 EVO continues this trend, arriving with the following specs:

The controller and its management of the bandwidth with other components is actually quite a unique one in the current Gen 5 market, as it is able to negotiate between Gen 5×2 bandwidth and Gen 4×4 bandwidth. Although auto-negotiation is something that has always existed in SSDs (thanks to PCIe architecture scaled down into PCIe Gen 5>4>3>2, etc.). However, this is something a little different and something that has been developed in order to respond to rising needs in more streamlined systems, PCIe cards, and developing SoC CPUs that have fewer lanes afforded to them (as well as lower power consumption thresholds and temperature limits).

Normally, if you were to put a Gen 5 SSD into a Gen 4 system, the SSD would downgrade to PCIe Gen 4×4, which is exactly what this drive does. But what about the reverse? With newer compact systems arriving with 5×2 bandwidth allocated to storage (as these mini newer Intel Core SoC PC systems, portable ultrathin laptops, and even RAID storage cards with multiple NVMe have begun to do), a PCIe Gen 4×4 SSD that is installed inside would be downgraded to PCIe Gen 4×2. Whereas a Gen 5×4 SSD would be able to use the full Gen 5×2 bandwidth. Ultimately, Samsung is clearly hoping to provide a single affordable drive in their EVO (i.e., affordable/value) series that is able to facilitate both the Gen 4 and Gen 5 compact systems, or those with more careful or curated PCIe lane allocation.

However, realistically, more current PC builders, gamers, and storage enthusiasts are going to question the widespread allocation of Gen 5×2 at the manufacturer level. There is certainly an argument to be made that 2023/2024 released mini PCs (i.e., Intel NUCs and their budget clones), NAS server systems, M.2 storage upgrade cards, and even pre-attached SoC motherboards (see Topton, Erying, and similar) are going to lead to more appearances of x1 and x2 speed M.2 slots.

However, there are very few Gen 5 examples in the market right now compared with Gen 4 and in those systems, the 5×2/4×4 Samsung 990 EVO will be of little benefit in bandwidth over other SSDs in the market. However, the PCIe bandwidth allocation and speed is not the only area in which Samsung has clearly decided is an area ripe for efficient redesign in storage.

The Samsung 990 EVO is also a DRAMless SSD. This means it is a drive that does not arrive with any onboard memory, instead relying on a client memory use system known as HMB – Host Memory Buffer. HMB means that the SSD will need to reserve a small area of RAM on the client machine it is installed inside. So, is this a good thing or a bad thing? DRAMless SSDs, which operate without a dedicated DRAM cache, offer several benefits. DRAMless SSDs, operating without a dedicated DRAM cache, present a unique set of benefits. Their primary advantage lies in cost-effectiveness, as the absence of DRAM chips leads to lower manufacturing costs, making these drives more affordable for consumers seeking SSD speeds on a budget. They are also more energy-efficient than their DRAM-equipped counterparts, consuming less power, which is especially beneficial in battery-powered devices like laptops and mobile phones, thereby extending battery life. The design of DRAMless SSDs is another plus; the elimination of DRAM chips allows for a more compact and streamlined form, ideal for space-constrained devices like ultra-thin laptops. These SSDs tend to be simpler and potentially more reliable due to fewer components, reducing the complexity of the drive’s architecture and possibly leading to fewer points of failure. Additionally, the lack of a DRAM cache can enhance data security, as there’s less risk of data being recovered from temporary storage after power loss. DRAMless SSDs are particularly suitable for read-intensive applications and basic tasks, where high write performance is not a priority.

However, DRAMless SSDs also have notable drawbacks, especially when compared to DRAM-equipped SSDs. The most significant downside is reduced performance, particularly in write speeds and handling large or intensive workloads, due to the reliance on slower NAND flash memory without a DRAM buffer. This limitation affects multitasking capabilities, as they lack a high-speed buffer for quick data access and organization. Some DRAMless SSDs compensate for the absence of onboard DRAM by using a portion of the system’s RAM (Host Memory Buffer), which can affect overall system performance, especially in systems with limited RAM. These SSDs may also have lower endurance due to continuous direct-to-NAND write operations, leading to faster wear of memory cells. Users might experience slower random access speeds and noticeable performance degradation over time as the SSD fills up and managing the mapping table becomes more complex. Consequently, DRAMless SSDs are not ideal for heavy workloads like video editing or gaming, where high-performance storage is crucial, making them a less suitable choice for users with demanding data needs.

While DRAMless SSDs offer benefits in terms of cost and power consumption, they are generally less suited for high-performance or heavy workload applications, making them more appropriate for budget-conscious consumers with moderate storage needs. Needless to say, Samsung has been quite clear about the performance and ideal deployment of the 990 EVO, with power efficiency and temperature management being crucial considerations. Therefore, HMB and a DRAMless design make a modicum of sense here – it just also means that Samsung’s first consumer Gen 5 SSD looks rather underwhelming in terms of traditional performance in comparison to existing Gen 4 and Gen 5 SSDs in the market right now.

The storage NAND on the drive is another comparatively low bar compared with existing fully featured Gen 5 and Gen 4 SSDs in the market (including Samsung’s own 980 Pro and 990 Pro). The Samsung 990 EVO is a drive that has been targeted to replace/refresh the 970 EVO and in THAT regard, it is a substantial upgrade! With high bandwidth allocation, higher degrees of saturation of it in traditional throughput, higher 4K random IOPS, and just generally better thermal/power management when in operation, the 990 EVO is a confident upgrade over the 970 EVO indeed. However, there is still the question of buying the 990 EVO as a storage drive for your Gen 4 system (or even Gen 5 premium rig) when even Samsung’s 2020 released 980 Pro drive dominates the 2024 released 990 EVO in pretty much all areas and is even a similar/lower price in a lot of retailers.

Samsung 990 EVO SSD	Samsung 990 Pro SSD

The storage NAND is of a lower layer count but is still Samsung’s in-house 3D TLC V-NAND. This, the lack of onboard DRAM, and (in certain deployments) the x2 speed all add up to a drive that doesn’t stand especially tall against its competitors at a glance. Nevertheless, there is also the argument that the Samsung 990 EVO is going to be the best SSD that you never realize that you already own in years to come! Its design is ripe for deployment as the OS drive at the OEM/factory level in the same way as the widespread use of the 970 EVO was for Windows machines and laptops the world over! Indeed, in a different context, the specifications for the Samsung 990 EVO would make it a GREAT upgrade for a Steam Deck or one of its many clones in the last 12-18 months. If the Samsung 990 EVO was a 2230 or 2240 sized SSD, this review would be very different – as the market is crying out for high performing, yet power-efficient small form factor M.2 SSDs – however, the Samsung 990 EVO’s 2280 length eliminates this use sadly.

Additionally, the fact the SSD arrives at 1TB and 2TB, but not a 4TB, is going to disappoint users who are looking at this drive in terms of efficiency but also know that our daily data creation rates are bigger than ever! However, we cannot really use this as a stick to beat the 990 EVO with, as this could be part of a staged rollout and a 4TB version coming down the line (Samsung already provides numerous 4TB NVMe SSD examples in other ranges). All the mixed points so far aside, I have to hand it to Samsung for releasing this DRAMless SSD that supports Gen 4 and Gen 5 deployment – yet still maintains a standard 600/1200 TBW (so over 0.3 DWPD). Jargon aside, that means that this power and heat-efficient SSD can withstand up to over 300/600GB of daily write/rewrite on the 1/2TB respectively. Outside of SSD cache utilization in servers and as a daily backup drive without differentials, this SSD is going to last a LONG TIME and hopefully way, way beyond the 5yrs manufacturer’s hardware warranty (standard across the industry). There are still points to be made that the lower performance bears closer examination on these number’s virtues, but nonetheless, this still all adds up to good durability for a drive that is going to be used in compact deployments where heat generation is a real concern!

The hardware, in the right context, is all great. But inevitably, we are going to need to look at how this all adds up to performance. Let’s put the SSD through some benchmarks with popular test software, as well as discuss the Samsung Magician client software and how it allows you to use your 990 EVO beyond just traditional target storage.

Using CrystalDisk, we got a good measure of the drive and verified that this PCIe Gen 5×2 / 4×4 SSD was indeed using the 5×2 lane. Additionally, the temp averaged out around 55C between each test being conducted and the highest temp registered for 68 degrees.

Samsung 990 EVO Gen 5 SSD Review – Performance and Software

It is REALLY important that we look at the performance of the Samsung 990 EVO SSD in the right frame of mind! We have reviewed A LOT of Gen 4 and Gen 5 SSDs here on NASCompares in the last few years, and we have to at least acknowledge that in terms of traditional throughput and responsive IOPS, the Samsung 990 EVO is going to come across lower in most cases. However, in the context of a DRAMLESS SSD and one that is designed towards more flexible deployment, we have more flexible thresholds in mind. Equally, Samsung has been very clear on the reported performance of the 990 EVO in their marketing, stating maximum performance numbers of 5000MB/s Seq Read and 4200MB/s Seq Write, as well as Read and Write 4K Random IOPS numbers of 800,000 and 700,000 respectively. These are good, healthy numbers and if sustained, would make this drive very attractive to those streamlined deployments. So, to the testing.

For the sake of fairness, let’s compare the results of the Samsung 990 EVO in some of its tests against the other DRAMless Gen 4 SSD we mentioned earlier in the review, the late 2022 released WD Black SN770, as then we have a much fairer means to frame the performance results:

Samsung 990 EVO SSD	WD Black SN770 SSD

Although the numbers are comparable and there are gains/drops on either side, the winner is largely going to come down to your perspective of priorities. If traditional throughput of chunking MB/s and GB/s is your focus, the SN770 has the upper hand. But for IOPS, larger-scale databases of volume, and deployments made up of high-frequency data, the Samsung 990 EVO holds its ground the firmest. Let’s conclude this review.

Samsung 990 EVO Gen 5 SSD Review – Verdict

All this adds up to a drive that, in a very specific context of use in a powerful, yet curated/limited PCIe allocated system (with concerns of heat and power use), is ready to be a hero! Samsung is clearly banking on this being an established future trend, and you cannot really blame them. Alongside numerous examples of strategic PCIe allocation in modern consumer hardware throughout 2023 and planned for 2024, there are also still question marks about just what percentage of PCIe Gen 5 bandwidth can actually be saturated long term on modern PC architecture before the inevitable overfilling of cache and performance numbers plummeting. We have seen numerous examples using synthetic testing that has shown the first and second phase of Gen 5 releases reach anywhere from 20-60 seconds of sustained transfer before bottling down! This raises the idea of a drive that does have the ability to hit those highs, because it doesn’t need to, and instead can provide a sustained performance number that on balance works out better (not just in those more compact deployments too).

However, I think the first drive from Samsung into consumer Gen 5 SSDs being DRAMless is a little odd and would have been best served as a derivation/2nd wave of Gen 5 Samsung SSDs that allow choice – much like how WD released the WD Black SN850, then followed it up with the WD Black SN770 DRAMless Gen 4 alternative and the WD Black SN850X premium upgrade. Starting with the DRAMless 990 EVO and rolling out at the same time as their competitors are providing comparatively priced Gen 5×4 alternatives with higher transfers and IOPS ratings might be something of a marketing misstep. Only time will tell, and, as ever, storage trends are first and foremost going to follow client hardware trends (the PS5 exploded the Gen 4 generation in a way that PC Gaming hadn’t yet), and more affordable Power use SoC/Mobile Embedded versions of Intel/AMD chips led to massive uptake in Gen 4 higher cap drives. The Samsung 990 EVO is an SSD with acceptable performance, IOPS numbers, durability, and power use when it’s looked at in its own context/light, but draws weak comparisons with bigger and bolder drives in the market. Gamers and serious power users will want to look elsewhere, but if you are looking for an OS drive or base SSD for your next micro/compact system, you are going to find a reliable and long-term drive choice here.

5 Reasons the Synology RS422+ Might NOT Be the NAS for You

While the Synology RS422+ NAS has numerous advantages, there are also some potential drawbacks that may dissuade certain users from investing in it. Here are the top reasons why you might want to consider alternatives to the Synology RS422+ NAS:

#1 – Default Memory is 2GB and Fixed

The RS422+ comes with a fixed 2GB memory, which may not be sufficient for some advanced applications or heavy multitasking. Upgrading the memory is not possible due to its fixed nature, limiting the potential for performance improvement as your needs evolve over time. This limitation can be particularly challenging for organizations with growing data processing requirements or those running memory-intensive applications.

#2 – 1GbE Default Network Connectivity

While the RS422+ can be upgraded to 10GbE, the default network connectivity is 1GbE, which may limit performance for users with high bandwidth requirements. This default connectivity may not be suitable for environments with multiple users accessing the NAS simultaneously or those transferring large volumes of data frequently.

#3 – Lack of Storage Expandability

The RS422+ has limited storage expandability, which could be a concern for users with growing storage needs. This limitation may necessitate the purchase of additional NAS devices or other storage solutions to accommodate increasing data volumes, potentially adding to the overall cost and complexity of the storage infrastructure.

#4 – Lack of M.2 NVMe SSD Slots

The RS422+ does not have M.2 NVMe SSD slots for cache or storage, which could limit its performance compared to other NAS devices that offer this feature. M.2 NVMe SSDs provide significantly faster data access and transfer speeds, enhancing overall performance and responsiveness, particularly for I/O-intensive tasks such as virtualization or large-scale file transfers. The absence of M.2 NVMe SSD support in the RS422+ may make it less attractive for users who require the highest possible performance from their NAS solution

#5 – The RS422+ is More Expensive than it should be!

Despite its numerous advantages and features, the RS422+ is priced higher than some of its competitors at £730 vs similar/better hardware in the desktop DS923+ at £550+, which may deter budget-conscious buyers. The higher cost may be difficult to justify, regardless of it being a rackmount and ‘business tax’, particularly for users who do not require all the advanced features offered by the RS422+ or for those who are not looking to scale up their storage needs significantly beyond older gens (many of which also still support traditional PCIe PCIe Cards). In such cases, more cost-effective NAS alternatives may provide better value for money, while still meeting the users’ storage and performance requirements. In conclusion, while the Synology RS422+ NAS has numerous strengths that make it a strong contender in the market, its lack of M.2 NVMe SSD slots vs the likes of the DS923+ and DS1522+, plus higher price point may be deal-breakers for some users. It is essential to consider your specific storage, performance, and budgetary requirements before making a decision, and to explore alternative NAS solutions that may provide a better balance of features and cost.

What We Said About the Synology RS422+ NAS in our FULL Review

Massive Synology RS422+ Review Article – HERE

YouTube Synology RS422+ Review – HERE

What Synology has produced in the RS422+ Rackstation NAS is an intriguing middle ground between their more cost-effective ARM-based rackmount solutions and their more expensive scalable and upgradable servers. On the face of it, you are getting a tremendously compact but capable 1U 4-Bay rackmount server that, as soon as you factor in the included DSM software and services, is very good value for businesses that want to move their data out of 3rd party cloud and into something they have full control over. Additionally, that CPU (though a fraction divisive when compared previously vs Intel chips in the desktop DS1522+) makes more sense here in this more affordable Rackstation solution. The lack of NVMe M.2 SSD slots, fixed 2GB memory and lack off rails I am less keen on here (and I am still a little on the fence about the way they have pursued 10GbE upgrades in this system) but you are still getting a very well built and small scale NAS solution here and Synology have found a good price point here for this complete solution. Additionally, the fact that Synology has not been so restrictive on HDD use in this system than in more enterprise solutions in 2022 is welcoming too, though they are still taking an odd stance on some drives nonetheless. Ultimately, I can recommend the Synology RS422+ Rackstation NAS to smaller business users, though looking for a compact and very easy-to-deploy NAS solution for surveillance, central business storage, additional backup layers and for DSM as a whole. Though multimedia users might want to give it a miss.

How to Upgrade the RAM in your Synology DS723+ to 32GB and 64GB RAM Officially/Unofficially

The Synology DS723+ NAS is a NAS system that arrives with an impressive middle ground between Power, Efficiency and Price, thanks to that AMD Ryzen R1600 CPU, flexibility in a 10GbE upgrade, storage expandability and (of course) arriving with ECC memory. The DS723+ is one of the latest generation of Diskstation devices (in the 2022/2023 series) that seems to be targeting the more advanced SMB user, prioritizing throughput and performance, whilst also doubling down on data integrity with things like BTRFS and ECC memory. However, the system arrives with 2GB, but can be upgraded officially to a very impressive 32GB (for the scale of the system)! So, there are users that might want to upgrade that memory on Day 1 in order to remove any kind of potential bottleneck down the line (VMs, Databases, Surveillance, etc) or even just users that have set up the device to their own unique setup – but noticed that Memory usage is constantly hovering at the 60-70%. Synology NAS systems use quite proficient intelligent background memory use and flushing, but nevertheless, there are still plenty of users who want to scale up the base-level memory. In this article, I will show you how to upgrade the memory on your Synology DS723+ NAS, but also I will show several 3rd party (i.e Unofficial modules) that I have tested in this NAS.

Upgrading your Synology DS723+ with Unofficial Memory – Pay Attention

Before we continue with the guide, it is worth highlighting that the DS723+ manufacturer, Synology, strongly recommends that you do not exceed the stated memory limit on their specifications page. They also highlight that using non-official memory in your Synology DS723+ may well result in them being unable to provide technical support, as this would be an unsupported setup. We at NASCompares cannot be held accountable for how you use this guide. However, below I will show you where to buy the individual memory and Synology DS723+ NAS device you will need. ONLY attempt this upgrade if you are comfortable with the terms laid out above by the manufacturer. Finally, it is also worth remembering that just because a system can SEE more than the official maximum memory, there is no guarantee that you will be able to utilize the full visible memory at once. Synology’s recommendations on the maximum memory supported by their NAS systems are often governed by three factors:

• The Recommended Maximum Supported Memory detailed by the CPU Manufacturer (e.g. Intel or AMD), which can also be a case of lanes and bandwidth allocation/availability
• The number of memory slots that Synology add to the system. This can be a case of a NAS only having 2 slots (with only 32GB modules supported by the brand) but the CPU supporting more than that being a physical conflict
• The Synology NAS might arrive with fixed/soldered memory for it’s default memory (e.g. the 2GB in the DS423+ or 4GB in the DS920+) but might also have a free memory upgrade slot – this leads to unusual memory caps such as the 6GB Maximum on the DS423+, despite it’s CPU supporting upto 8GB.

If you choose to go ahead with unofficial memory, afterwards, it is highly recommended to test the full quantity available with VM testing (assigning bulk memory to each virtual image) and running at the same time to see if it is utilized.

Synology Official Memory vs Unofficial Memory from Crucial, Kingston, Sabrent, etc?

Luckily Synology provides a wide range of official memory upgrades that can be purchased from numerous retailers online, however, they are generally more expensive than the 3rd party equivalents (see example above). Now, there could be a few good reasons for this. Firstly, these memory sticks are first-party and specifically selected to work on the Synology NAS systems (taking alot of the searching out of it for people in researching speeds, frequencies and supported PIN numbers), and officially branded components for any hardware manufacturer are always pricier.

Next, they do not have the rotation of stock that Crucial or Kingston has and therefore, the flexibility in pricing they might have is not available. Lastly, the Synology memory will often be ECC memory (especially in recent released NAS systems by them) and ECC memory always commands a higher price. However, given this memory is likely manufactured by a 3rd party, that does make it a little painful sometimes for smaller Synology NAS users who look at official memory and its often 2-3x pricepoint of equivalent modules from Kingston, Crucial and Samsung. So, in this guide we talk about upgrading your memory with both official and unofficial memory, what happens when you do and if there are risks to factor in. If you are a little unsure about whether you need to use ECC memory in your specific Synology NAS setup, you can watch the video below detailing the pros, cons and more:

Synology DS723+ Official/Unofficial Memory Upgrade – Step 2, Physical Installation

What you will need:

• A Synology DS723+ NAS – Obviously
• 1/2x Memory Upgrade Modules (Ranging from 4GB to 16GB and 32GB Individual Modules – Link below for Tested RAM modules from Crucial, Kingston, Samsung, Timtec and Synology Official Memory too:

VERY IMPORTANT – The Links used in the article below towards the correct unofficial memory are occasionally changed (beyond my control) as it will direct you to the site in your own region/country. MAKE SURE to check that the memory module (especially 16 and 32GB SODIMM modules) are DUAL RANK or ‘DR‘, as Synology NAS typically have trouble with SR/SINGLE RANK modules.

• (OPTIONAL) Anti-static gloves and Envelope – useful to eliminate static charges and also to store the removed older official memory sticks):

First, we need to ensure the Synology DS723+ is completely powered down/off and the mains power has been disconnected. It is recommended that you remove the Hard Drive or SSD that you have installed before accessing the RAM as it may block the slots. Additionally, you should remove the hard drive media as the unit will be moved around a lot during the memory installation and this could damage the drives. Be sure to keep a note of the drives that you remove and the order they were installed (HDD Bay 1, HDD Bay 2, etc) as installing the drives in the wrong slots could damage any existing RAID you have setup internally.

Next, we need to access the memory upgrade panel. Now, if you are just adding the existing memory, you can just add the additional module to the available SODIMM slot. However, if you are upgrading the system’s memory with new pairs of memory sticks (eg upgrading from the default 2GB to 32GB with 2x16GB), you will need to remove the old memory (remember to store it in an antistatic bag afterwards)

If you are removing the original memory, be sure you eject the official memory sticks using the clips on either side of the slot, as well as only holding the memory sticks by the narrow side edges, never touching the chips or board of the money or NAS.

Once you have removed them, they can either be stored away for a later project, installed in a compatible laptop or sold on eBay etc to make a little cash back!

Once they are clear, install one or both of your chosen unofficial DDR4 SODIMM memory modules in the available slots, making sure that you click them both in with the clips on either side.

Synology DS723+ Official/Unofficial Memory Upgrade – Step 2, Checking the Unofficial Memory is Recognized

What you will need:

• A web browser (Chrome, Safari, Firefox, etc) on a Windows, Mac or Android Machine) accessing the Synology DS723+ user-interface as you normally would.

Next, you need to power up your Synology DS723+ NAS and access it as you normally would. If you are buying this NAS first time and have yet to set it up, there are numerous first-time set-up guides and tips on the YouTube channel here – that will get you from the hardware installation to set up the Synology DS723+ NAS for use. Once the NAS user interface (UI) is ready to go, head over to the hardware specification page shown here:

As you can see in the image above, the Synology has recognized the increased memory. It is still recommended to head to Step 4 below to see how to use the official memory test feature of the system.

Synology DS723+ Official/Unofficial Memory Upgrade – Step 3, Unofficial/Unsupported Memory Tested

As mentioned earlier, Synology is pretty clear about its position on users opting for non-Synology memory in their systems or exceeding the officially stated maximum capacity of the DS723+. They feel this is using the system in a configuration that is outside of the guaranteed performance and stability that they advertise. This means that if your system encounters issues as a result of these unsupported configurations, they (at best) will have difficulty recreating this configuration to provide support or (at worst) refuse to provide support as they have been pretty clear on the setups that they state the DS723+ can run with. However, there is no avoiding that there have been countless examples of Synology NAS systems functioning perfectly well with 3rd party memory (YouTube Playlist of Synology NAS 3rd Party memory Tests HERE), so here are some examples of memory modules we tested on the Synology DS723+ NAS (including model ID and links as needed – again, DOUBLE CHECK THE MODEL ID before you buy, as retailers will check page links):

So, those were the three unofficial memory types that I tested on the Synology DS723+ NAS. However, it is VERY important that (regardless of whether you choose official or unofficial memory for your NAS upgrade) you check that your memory is working perfectly. Do check this; you should use the built-in Memory Testing facility of Synology Assistant for PC/Mac. Below is how to conduct the test.

Synology DS723+ Official/Unofficial Memory Upgrade – Step 4, Checking the Memory is Usable

There are several ways to check the memory is working on your Synology DS723+ correctly. One easy method that can be done very quickly is using the Synology Memory Test tool.

To run a memory test:

1. 1. Download and install the Synology Assistant, where you can find the memory test function. The application is available at Download Center.
   2. Open Synology Assistant, click and enable the memory test service.

1. 1. Select the device where you wish to run the test and click Memory Test.

During the memory test, your Synology NAS will be rebooted. It will recover after another reboot if its memory is normal and passes the test. However, if the memory test fails to finish or shows that there is an error, the memory may be faulty. In this case, you are strongly recommended to return your Synology NAS for repair. Just in case you have installed a non-Synology memory module, please remove it and rerun the memory test.

Though once again you should remember that Synology do not recommend using memory modules that are not from Synology themselves, so this test may not be indicative of the health of unofficial memory in your Synology NAS. Alternatively, you can perform as many actions and processes as possible (scans, copy/pastes, thumbnail generation, transcode a 4K file, RAID changes, synchronisation, etc) at once to see how the task manager and resource monitor behaves in the Synology DS723+. It should spike each time and at a greater height as you do more and more and once it exceeds the memory you had previously installed, this is a good confirmation that the installation is working fine. Alternatively, you can temporarily allocate chunks of memory and then that is a much more reliable test. Install the virtual machine application for the Synology DS723+ (P.S. for Synology users it is the Virtual Machine Manager and for QNAP it is the Virtualisation station). Then you can create individual VMs (it is alot easier than it sounds and the Synology DS723+ VM software is very user-friendly) then allocate a large number of GBs (Gigabytes) of memory to each one. When you have created 3 or 4 individual virtual machine containers on the Synology DS723+ software, then you can run them all at once and that will immediately use almost all the memory at once! If there are any issues with the memory, it will show here almost immediately. If no problems, then you know the Synology DS723+ unofficial Crucial/Kingston memory installation as successful. You can then delete the VMs in the virtual machine software and then free up all that memory again.
