A Guide to the Best 5/6-Bay NAS Drives to Buy Right Now
In recent years, the appeal of 5-Bay and 6-Bay NAS systems has dramatically increased, particularly since 2023/2024. Previously, home and small-business users tended to opt for either modest 2/4 Bay systems or jump to the larger 8-Bay models when needing more storage capacity. The growing popularity of 5-Bay and 6-Bay models can be attributed to two key factors. Firstly, the advent of larger capacity drives, reaching up to 22TB and soon 24TB, enables even mid-sized NAS systems to surpass the 100TB storage threshold easily. Secondly, there’s a heightened awareness of data redundancy needs and skepticism about the reliability of single-drive safety in RAID 5 configurations, compared to the two-drive failure protection offered by RAID 6. This combination has made 5-Bay and 6-Bay NAS setups, especially those using large drives in a RAID 6 array, much more accessible and desirable. NAS manufacturers have taken note of this trend, leading to an expanded range of 5-Bay and 6-Bay NAS solutions that vary in hardware capabilities, power, and price. In this context, I aim to highlight my top picks for 5-Bay and 6-Bay NAS drives to consider in 2023/2024, each standing out for unique reasons. Let’s explore the best 5-Bay and 6-Bay NAS servers that should be on your radar.

Honourable Mention: 5/6-Bay NAS Drive – The LincStation N1
0-32TB M.2 NVMe + 10TB SATA HDD / 16TB SATA SSD, 4+2-Bays, 4xM.2 NVMe 2280, Intel N5105/N5095 CPU, 16GB Memory, 2.5Gbe Port, HDMI+DP 1.4 60FPS 4K, UnRAID License Inc, 2yr Warranty

What I said in my review Oct 16 ’23:
When evaluating the Lincplus N1 NAS, context is paramount. Keeping in mind its price point and the brand’s objectives, as well as understanding how an SSD-centric system can fit into this mold, you’ll likely be thoroughly pleased with this NAS. For a mere $279, it offers an unmatched combination of hardware capabilities. The silent operation, bundled UnRAID software, two-tier storage, and genuine turnkey out-of-the-box deployment culminate into a device brimming with potential. It caters to both newcomers to private server ownership and seasoned home lab enthusiasts. Certain concessions were inevitable to attain this attractive price. Seasoned flash industry professionals might bemoan the absence of ECC memory, the use of a consumer-grade CPU, and limitations placed on the bandwidth and speeds for the m.2 NVMe slots. Even though the software is genuinely turnkey and the system is ready to run immediately after unboxing, UnRAID does come with its learning curve. It might be more user-friendly compared to other container-based GUIs, but there’s still a learning curve. Additionally, the default UnRAID settings could be better tailored to this SSD-driven system.
Hopefully, future firmware updates might address this. Such discrepancies are expected when the hardware is developed by one entity and the software by another. This dichotomy can lead to inconsistencies, such as those seen in drive monitoring results, raising questions about the demarcation of responsibility between the two entities. However, overlooking these minor points, the N1 stands out as a commendable alternative to a full DIY approach. It not only saves money and time but also offers a ready-to-use, compact solution. Provided you acknowledge and accept the inherent compromises, the N1 emerges as a notable midpoint in the burgeoning server market, bridging the gap between custom-built and all-inclusive turnkey solutions.

What I said in my review June ’22:
The Synology DS1522+ is a good NAS drive and most business-focused users are going to appreciate what this newer configuration of hardware is able to provide. There was never any doubt in the extent to which this new NAS would support DSM7, and given its architecture, there is virtually nothing in the popular NAS software that this system cannot do. Likewise, having the option of 10GbE on a Diskstation of this scale will be hugely attractive to some, though the proprietary means with which you need to upgrade is arguably less desirable.
The R1600 CPU is a good choice of processor for file handling and simultaneous tasks, as is the 8GB of memory that this system arrives with, plus the potential to ramp it up to 32GB. After that though, the desirability of this system to home users and multimedia users is a little less compelling and with such a large audience of users who look at NAS for their media streaming, the DS1522+ not featuring a more graphically enabled chip will leave them somewhat underwhelmed. Bottom line, the DS1522+ is a solid and full DSM7 supporting system here and you cannot fault the design, internal/external performance and ease of use of this Synology NAS. However, there will always be users wondering why this NAS never arrived with an Intel chip.

Best Value 6-Bay NAS – The Asustor Flashstor 6 NVMe Flash Server
0-48TB, 6x M.2 NVMe 3×1 Bays, Supports 2x USB Expansions, N5105/N5095 4-Core CPU, 4-16GB DDR4 (non-ECC) Memory, 2x 2.5Gbe Port, 3yr Warranty (10GbE version = FS6712X Flashstor 12 Pro for $799 HERE)
Current Price/Availability on Amazon – $499

What I said in my review June ’23:
I cannot stress enough how impressed I am that the Flashstor 6 and Flashstor 12 Pro are priced at $499 and $860, respectively, given the level of hardware on offer here. These are by no means enterprise-grade NAS server solutions, nor should they be thought of as such. However, given the cost of typical fully featured 4x HDD solutions from their competitors and the brand themselves, which often start at $550 and above, it is quite remarkable that the six M.2 SSD system with comparable internal hardware comes in at $499. As long as a user keeps their expectations in line with what this cost versus its capabilities, it’s really tough to argue with the price point that these two devices have arrived at on the market. The Asustor FS6712X Flashstor 12 Pro NAS presents a unique offering in the NAS market, leveraging NVMe technology to provide high-capacity, ultra-high-performance storage. The device’s design, with its rhombus-shaped enclosure and twelve M.2 NVMe slots, sets it apart from traditional NAS devices and offers a sleek and modern aesthetic.
The tool-less drive installation mechanism makes it easy to set up and expand the storage capacity. However, there are some considerations to keep in mind. The limited number of PCIe lanes provided by the Intel Celeron N5105 processor may restrict the performance of high-speed NVMe drives. The single 10GbE LAN port also presents a potential network bottleneck, limiting the device’s overall network performance. Users seeking maximum performance and network throughput may find alternative solutions better suited to their needs. Despite these limitations, the FS6712X shines as a storage solution for users who prioritize high-capacity storage, quiet operation, and low power consumption. The device’s ability to directly output 4K video, along with its range of Asustor-approved apps, makes it an excellent choice for media distribution and presentation. In terms of pricing, the FS6712X comes with a price tag of $850+. While this may appear high at first glance, it is comparable to 8 bay drive NAS SATA devices and many of those do not even include NVMe slots or 10GbE. Users looking for a more cost-effective option can consider the Flashstor 6, which offers half the number of slots and 2x 2.5GbE enabled ports for $499.
As the cost of flash modules continues to drop, and larger capacity drives become available all the way up to 8TB (even without QLC), the FS6712X provides an attractive solution for those seeking high-capacity and high-performance NAS storage. While some underlying performance relativity by the end user needs to be factored in and hardware limitations exist thanks to the use of that Celeron to remain budget-friendly, the FS6712X is a tremendously smart move by Asustor. A well-designed NAS that presents a much more confident solution demonstrating the benefits of NVMe-focused NAS devices to an audience that would have assumed such things are way, WAY outside the realms of affordability!

Bet Hardware 6-Bay NAS – QNAP Triple Tier TS-855X Server
0-130TB SATA HDDs, 0-16TB SATA SSDs, 0-16TB 3×4 M.2 NVMes, 6+2+2-Bays, C5125 8-Core Atom CPU, 8-128GB Memory, 1x 10GbE and 2x 2.5GbE Ports, 2x PCIe 3×8 Slots, 3yr Warranty

What I said in my review June ’23:
I have to say, I am INSANELY impressed by how much bang for buck is being included in the TS-855X and although it is not the most powerful device in the market (arguably intentionally, as it favours the more affordable Atom over a xeon), it is a sensible workhorse of a NAS. On the positive side, the QNAP TS-855X NAS comes with numerous strong selling points. The device offers large storage potential, especially with the ZFS file system, making it a powerhouse for data management. The choice of CPU is also sensible, providing a balance between performance and cost-effectiveness. The inclusion of the QTier tool is particularly appealing, adding a layer of efficiency to the storage management. Another big plus is the user-friendly GUI for ZFS in QuTS, making it accessible for users with varying levels of technical expertise. The three-tier storage options and support of ECC memory with a maximum of 128GB further enhance the device’s versatility and potential. Moreover, the TS-855X provides a wealth of expansion options and comes with 8 camera licenses with QVR Pro/QTS. The well-ventilated design contributes to thermal efficiency, ensuring optimal performance, while its support for the latest 22TB and soon-to-be-released 24TB drives future-proofs your investment.
However, the TS-855X is not without its drawbacks. While the two SATA SSD bays provide extra storage options, they would have been better if they were U.2 slots, which offer faster speeds. Although the device supports ECC memory, the initial 8GB memory in the base model is non-ECC, which might not be optimal for all ZFS services. The memory capacity might also be somewhat low for users with intensive data needs. Furthermore, the software can sometimes be inconsistent under heavy use, and it has a steeper learning curve compared to competitors like Synology. Finally, the pricing structure for the TS-855X is a mixed bag. While some users may find the cost reasonable given its features, others might feel it’s a bit steep for what it offers. Therefore, while the QNAP TS-855X NAS offers a plethora of attractive features and strong performance, it’s worth keeping in mind that a spend of a few hundred more dollars opens the door to Intel Core-powered NAS in the TVS-hx74 series or more powerful Xeon triple-tiered systems such as the TVS-h1288X. If you want power, but on a budget, it’s a great choice!
