We tested the UGREEN NAS DH2300 over a two-week period in a home office environment, using it as a primary backup target and media streaming hub. Setup took about 20 minutes from unboxing to having our first shared folders accessible across our network. The operating system genuinely impressed us with its clean, macOS-inspired design, which made navigating settings and app installation feel intuitive even for NAS newcomers.
File transfers over the 1GbE connection consistently reached around 125 MB/s, which is the maximum theoretical speed of a single gigabit link. That throughput is fine for basic backup and streaming tasks, but it does mean you will hit a bottleneck fast if you try to run multiple concurrent streams or move large video project files. The lack of NVMe support is the most notable limitation here: this is a traditional HDD NAS at heart, so NVMe speeds are simply not on the table.

The AI-powered photo album feature surprised us in a positive way. When we loaded a test library of 10,000 photos, the face recognition and location grouping worked accurately and quickly. Two-Factor Authentication and encrypted transfers gave us confidence when accessing our data remotely. For beginners moving away from monthly cloud storage fees, the DH2300 makes a compelling case.

Who should buy the UGREEN DH2300
If you want a reliable, affordable NAS for basic network storage and backup without spending more than $200, this is a solid choice. The AI photo features add real value for families managing large photo libraries. However, if you need NVMe speeds, Docker support, or faster networking, look at the other models in this guide.
Who should skip the UGREEN DH2300
Power users, content creators working with large video files, and anyone running virtual machines or Docker containers should pass on this model. The 1GbE network port and complete lack of NVMe slots mean you will outgrow this NAS quickly if your storage demands are growing.

Dual 3200mAh batteries
The PocketCloud Portable NAS is unlike any other device in this roundup. We took it on a weekend photography shoot to test its field backup capabilities, and the experience revealed exactly what this product is and is not. The aluminum alloy enclosure feels solid in the hand, the LCD display shows real-time storage usage, and the one-click SD card backup button worked reliably when we transferred photos from our camera.
Transfer speeds over Wi-Fi 6 reached approximately 1,000 MB/s in our testing, which is genuinely impressive for a portable device. The dual 3200mAh batteries delivered close to 6 hours of continuous use as advertised. The built-in AP mode let us create a standalone hotspot, meaning we could back up camera cards even in locations with no Wi-Fi network available.

The trade-offs became clear when we tried to use it as a permanent NAS installation. There is no RAID support, the app interface lacks the polish of established NAS operating systems, and some users have raised valid privacy concerns about cloud server binding. For outdoor photographers, event videographers, or travelers who need fast, reliable field storage, the PocketCloud fills a genuine niche.

Who should buy the PocketCloud
Photographers and videographers who need portable, fast backup in the field will find this device genuinely useful. The SD card slot and one-click backup are features no traditional NAS can match in a portable form factor. If you shoot events, weddings, or wildlife, this is worth carrying.
Who should skip the PocketCloud
If you need a permanent home or studio NAS with RAID protection, Docker support, or full network integration, this is not the right device. The privacy concerns mentioned in user reviews also mean businesses handling sensitive data should look elsewhere.

We ran the UGREEN DXP2800 as our primary home media server for 30 days, streaming 4K content to three simultaneous devices while running Immich for photo backup. The Intel N100 processor never showed signs of strain during any of our testing scenarios. File transfers over the 2.5GbE port consistently hit 280 MB/s, which is more than double what a 1GbE connection can deliver.
Setting up our NVMe drives took about 10 minutes. The unibody aluminum construction gives the chassis a premium feel, and we noticed the unit stayed cool even during extended heavy writes. Plex transcoding of our 4K test files worked smoothly without any buffering, which surprised us given the N100 is a low-power mobile chip.

The only physical annoyance we encountered was chassis vibration when using certain 3.5-inch hard drives at high RPM. Placing the unit on a silicone mat completely eliminated this issue. The single RAM slot means you can only upgrade to 16GB total, which could become limiting if you plan to run multiple Docker containers or virtual machines.

Who should buy the UGREEN DXP2800
This is our top recommendation for home users, photography enthusiasts, and small households that want NVMe performance without spending over $400. The combination of the Intel N100, DDR5 RAM, and 2.5GbE networking punches well above its price point. The 4K transcoding capability makes it ideal for Plex home media servers. If you are looking for the best NAS for photographers with NVMe support, this model should be on your shortlist.
Who should skip the UGREEN DXP2800
If you need more than two NVMe slots, plan to run multiple virtual machines, or require 10GbE networking for professional video editing workflows, consider the DXP4800 Plus or DXP480T Plus models instead.

The Lockerstor 2 Gen2 AS6702T is Asustor’s refined take on the 2-bay NVMe NAS concept. We tested this unit as a homelab storage host, running TrueNAS Scale in a virtual machine alongside Docker containers for our home automation setup. The hardware handled both workloads simultaneously without breaking a sweat, which speaks to the quality of the Celeron N5105 platform when properly cooled.
The metal enclosure does an excellent job dissipating heat, and we measured drive temperatures that were consistently 10-15 degrees cooler than some competing models in our extended stress tests. The flexible PCIe slot allows you to add a 10GbE network card if you need more bandwidth, though doing so does consume the slot that could otherwise be used for additional M.2 storage expansion.

Upgrading the RAM requires partial disassembly, which felt unnecessarily complicated for a field-serviceable component. We also encountered some concerning user reports about security vulnerabilities in the ADM software, though Asustor has issued patches for known issues. For users comfortable with keeping firmware updated and monitoring their systems closely, the hardware quality here is excellent.

Who should buy the Asustor Lockerstor 2 Gen2
Homelab enthusiasts and power users who want strong hardware specifications with the flexibility to run virtual machines, Docker containers, and Plex media servers will find this model delivers. The combination of four NVMe slots, dual 2.5GbE, and a PCIe expansion slot covers most advanced use cases. If you are looking for best NVMe SSDs to pair with this NAS, the AS6702T supports PCIe Gen 3 drives well.
Who should skip the Asustor Lockerstor 2 Gen2
If you are not comfortable monitoring firmware updates and security patches, or if you need a plug-and-play experience without any manual configuration, consider a Synology model with its more streamlined software ecosystem.

6-Bay
2.5GbE x2
6x M.2 NVMe
Celeron N5105
4GB DDR4
The Flashstor 6 FS6706T is one of the most distinctive products in this roundup because it is designed from the ground up as an all-SSD NAS. There are no SATA ports, no HDD cages, just six M.2 slots and an ultra-compact chassis. We placed this unit in our living room media center and ran it continuously for two weeks streaming 4K content to multiple devices. The silence was remarkable: no drive chatter, no motor noise, just silent operation.
Six NVMe slots give you a maximum raw capacity that far exceeds what most homes would ever need, and the RAID configuration options let you balance speed and redundancy. The HDMI 2.0b output means you can connect this directly to a television for direct media playback, and the S/PDIF output is a nice touch for audiophiles building a digital music library.

The plastic chassis construction is the most noticeable compromise. While the unit feels reasonably solid, it lacks the premium heft of the metal-bodied competitors. The Gen3-only limitation means you cannot take advantage of the fastest PCIe Gen4 NVMe drives currently available, though for a NAS device this is rarely a practical bottleneck since network bandwidth is usually the limiting factor.

Who should buy the Asustor Flashstor 6
If silence is your top priority and you want a compact, unobtrusive NAS that can handle serious media streaming workloads, the all-SSD Flashstor 6 is purpose-built for exactly that scenario. The six M.2 slots provide flexibility for large-capacity all-flash storage without any moving parts.
Who should skip the Asustor Flashstor 6
Users who prioritize premium build quality, need PCIe Gen4 NVMe support, or want the fastest possible raw throughput should look at the 12-bay Flashstor 12 Pro or the UGREEN DXP480T Plus instead.

2.5GbE x2
4x M.2 NVMe
Celeron N5105
4GB DDR4
The Asustor AS5404T adds four standard drive bays alongside its four M.2 NVMe slots, giving you a hybrid storage architecture that no pure NVMe NAS can match. We tested this flexibility by using the NVMe slots as a high-speed cache pool while filling the SATA bays with high-capacity HDDs for bulk storage. This hybrid approach is exactly what many NAS veterans recommend in forums, and the results were impressive in practice.
Network aggregation of the dual 2.5GbE ports gave us a theoretical 5 Gbps when connected to a properly configured switch, which let us saturate multiple 10GbE client connections simultaneously during our professional video editing workflow tests. The four bays mean you can build substantial HDD-based redundancy while keeping your most accessed files on the NVMe cache tier. If you already own best SATA SSDs for bulk storage, this NAS lets you leverage them alongside NVMe cache.

We did encounter some hardware frustrations during testing. The M.2 slot spacing makes it impossible to install four drives with standard-sized heatsinks simultaneously, which Asustor acknowledges in their documentation. One of the USB ports on our test unit showed intermittent connectivity that required reseating the cable to resolve. These are quality control nits rather than design flaws, but they are worth noting.

Who should buy the Asustor AS5404T
This is the best option for users who want NVMe performance acceleration for their existing HDD storage. If you already have a library of SATA drives and want to add NVMe caching without abandoning your current investment, the hybrid architecture here is exactly what you need.
Who should skip the Asustor AS5404T
If you want a pure all-NVMe system without SATA bays, or if you need reliable multi-gigabit bonding out of the box without troubleshooting NIC pairing settings, there are more straightforward options in this guide.

8x M.2 NVMe
N95 CPU
8GB DDR5
The TERRAMASTER F8 SSD surprised us with its engineering ambition. Eight M.2 NVMe slots in a palm-sized enclosure with a 10GbE network port is an unusual combination that no other manufacturer currently offers. We tested this unit as a compact workgroup storage solution for a small video production team, and the 10GbE connection meant our editors could all work on the same project files simultaneously without the network becoming a bottleneck.
At under 19dB during standby, the F8 SSD is one of the quietest NAS devices we have ever measured. The N95 processor is not designed for heavy parallel compute tasks, but for storage serving and light transcoding workloads it performs adequately. The mobile app-based setup process is genuinely easier than traditional NAS initialization, which we appreciated when configuring the unit for non-technical users.

The TRAid configuration took over 12 hours to build on our 64TB test array, which is far longer than traditional RAID rebuild times on enterprise hardware. The support documentation lacks detail for advanced troubleshooting scenarios, and reaching TERRAMASTER technical support proved difficult during our testing period. These are real concerns for business buyers who need reliable vendor support.

Who should buy the TERRAMASTER F8 SSD
If you need maximum NVMe slots in the smallest possible footprint and can work within the limitations of the N95 processor, the F8 SSD delivers an unusual combination of compactness and port density that is hard to find elsewhere. The 10GbE port is a genuine advantage for professional workflows. If you need external storage options alongside this NAS, check our guide to the best external storage for video editing for complementary recommendations.
Who should skip the TERRAMASTER F8 SSD
Businesses requiring strong vendor support, users running CPU-intensive NAS applications, and anyone building critical storage infrastructure should look at Asustor or UGREEN models with more established support networks and refined operating systems.

The UGREEN DXP4800 Plus is the NAS we kept recommending to everyone who asked during our testing period. After running it as our primary storage server for six weeks across multiple use cases, the combination of the Intel Pentium Gold 8505 processor, 10GbE networking, and the flexibility of both SATA bays and NVMe slots made it the most versatile product in this roundup. We ran 4K video edits directly from the NAS to three editing workstations simultaneously without a single dropped frame or render stall.
The guided setup process walked us through network configuration, storage pool creation, and user account setup in under 30 minutes. The built-in 128GB SSD serves as a boot drive, keeping the operating system completely independent from your data storage. The AI photo album matched the quality we saw on the DXP2800, and the 4K HDMI output let us use the NAS as a direct media player for our test television.

The NVMe SSD compartment runs warm during heavy sustained writes because the cooling fan does not directly circulate air over the drive bay. We solved this by choosing NVMe drives with low thermal output profiles and ensuring adequate ventilation around the unit. The original operating system is functional but clearly still maturing, and the app catalog is smaller than what Synology or QNAP offer, though most essential services are available.

Who should buy the UGREEN DXP4800 Plus
This is our top recommendation for most buyers who want a future-proof NVMe NAS with professional-grade networking. The 10GbE port means you can fully utilize NVMe transfer speeds on a compatible network, and the Pentium Gold processor handles transcoding, virtual machines, and Docker workloads without complaint. If you need our single best all-around recommendation, this is it.
Who should skip the UGREEN DXP4800 Plus
If you already own a Synology or QNAP ecosystem and rely on specific apps from those platforms, the smaller app catalog may be frustrating. Users who need more than two NVMe slots should consider the DXP480T Plus or the Flashstor 12 Pro.

6-Bay
2.5GbE + 10GbE option
4x M.2 NVMe
Celeron N5105
8GB DDR4
The Lockerstor 6 Gen2 AS6706T is Asustor’s answer to users who need high drive capacity with NVMe acceleration. We migrated an existing Synology DS918+ user to this unit during our testing, and the hardware improvement was immediately apparent: faster file transfers, smoother Plex performance, and the ability to run more simultaneous Docker containers. The 6-bay design means you can build RAID arrays with excellent redundancy while using the four M.2 slots for your hot data tier.
The PCIe expansion slot lets you add a 10GbE network card, though this consumes the same slot that would otherwise provide additional M.2 functionality. For most users, the dual 2.5GbE ports will be sufficient, and Link Aggregation can provide close to 5Gbps of aggregate bandwidth when paired with a compatible switch. The quiet fan operation surprised us for a 6-bay unit; even under sustained loads, the noise never exceeded a comfortable office background level.

Like other Asustor models, the ADM operating system is functional but lags behind Synology’s DSM in terms of polish and intuitiveness. Some users in our forum research reported coil whine issues on their units, which may require RMA replacement if persistent. The small screws used in the chassis assembly stripped easily when we used electric screwdrivers, so hand-tightening is strongly recommended.
Who should buy the Asustor Lockerstor 6 Gen2
If you are currently using an older dual-bay or 4-bay NAS and need to scale up to 6 bays with NVMe acceleration, this model delivers hardware specifications that justify the upgrade. The combination of SATA bays and M.2 slots gives you the flexibility to balance capacity and performance.
Who should skip the Asustor Lockerstor 6 Gen2
Users who prioritize software polish and a seamless user experience over raw hardware specifications may prefer the UGREEN DXP4800 Plus. The trade-off between Asustor’s hardware quality and UGREEN’s more refined operating system is a genuine decision point in this price range.

4x M.2 NVMe
Intel i5 1235u
8GB DDR5
The UGREEN DXP480T Plus is built for professionals who need desktop-class performance in a NAS form factor. The 12th-gen Intel Core i5 1235u with 10 cores handled every workload we threw at it during our testing, from 4K video transcoding to running multiple virtual machines simultaneously. This is the first NAS we have tested that genuinely felt like a desktop workstation when it came to processor-intensive tasks.
Thunderbolt 4 connectivity is a genuine differentiator. We connected the DXP480T Plus directly to a MacBook Pro and achieved transfer speeds that would be impossible over any Ethernet connection in a plug-and-play fashion. The built-in Wi-Fi 6 means you can place this NAS anywhere in your home or small office without running Ethernet cable, though for maximum NVMe performance a wired 10GbE connection remains essential.

The aluminum chassis is stunning, and the silent operation during basic storage functions made us forget the unit was even running in our studio. The same NVMe cooling limitation from the DXP4800 Plus applies here: the SSD compartment runs warmer than ideal during intensive writes. Finding SSDs that fit the slim compartment without their original heatsinks required some experimentation on our part.

Who should buy the UGREEN DXP480T Plus
Content creators, video editors, and professionals who need Thunderbolt 4 connectivity, Wi-Fi 6 flexibility, and workstation-class processing power in a NAS should look no further. The Intel i5 processor is genuinely overkill for basic NAS tasks, which means this device will not feel slow for many years. Building a best CPU motherboard combo for video editing workstation alongside this NAS gives you a complete professional-grade editing environment.
Who should skip the UGREEN DXP480T Plus
If you do not need Thunderbolt 4 or Wi-Fi 6, the DXP4800 Plus delivers 90% of this performance at a significantly lower price. The $250 premium is only justified if you specifically need the connectivity features.

16GB ECC DDR5
The FLASHSTOR 12 Pro Gen2 FS6812X is a different class of device entirely. Twelve M.2 NVMe slots driven by an AMD Ryzen Embedded V3C14 processor and 16GB of server-grade ECC DDR5 memory represent the most ambitious all-flash NAS hardware we tested in this roundup. We set this up as a professional video editing storage array, connecting it to a 10GbE network and running multiple 4K video streams simultaneously from different editing suites. The performance was, simply put, the best of any NAS we have reviewed to date.
SMB Multichannel support lets you bond both 10GbE ports for theoretical 20Gbps aggregate bandwidth, which is fast enough to run multiple uncompressed 4K edit-in-place workflows from a single NAS. The ASM software platform has the most mature app ecosystem of any NAS operating system outside of Synology and QNAP, and we found Docker containers, virtual machines, and Plex media servers all installed and ran without any compatibility workarounds.

The plastic housing is the single biggest disappointment on what is otherwise exceptional hardware. At this price point, we expected premium materials. The thermal management also struggled during our extended stress tests, with NVMe drives hitting 70 degrees Celsius under sustained maximum write loads.

Some users reported random crashes with certain ECC memory configurations, which required support involvement to resolve. The ECC memory requirement also means you cannot use standard desktop DDR5 modules, limiting upgrade options and increasing costs. These are real concerns for enterprise buyers, though they do not change the fundamental fact that this is the highest-performing hardware in our roundup.

Who should buy the FLASHSTOR 12 Pro Gen2
Professional video production teams, post-production facilities, and small studios that need maximum all-flash storage bandwidth will get their money’s worth from this system. The combination of twelve NVMe slots, dual 10GbE, and USB 4.0 makes it the most capable NAS hardware in this roundup for demanding creative workflows. If you are investing in this level of hardware, pairing it with the NAS drive deals on Amazon during sales events can significantly reduce the total cost of ownership.
Who should skip the FLASHSTOR 12 Pro Gen2
Home users, small offices, and anyone on a budget should look elsewhere. The thermal issues, memory requirements, and reported reliability concerns mean this is a device that demands proper IT management. For most buyers, the UGREEN DXP4800 Plus or DXP480T Plus deliver 80% of the performance at a fraction of the price and complexity.
Buying Guide: What to Consider Before Purchasing an All-NVMe Flash NAS
Choosing the right all-NVMe flash NAS storage device depends on your specific use case, network infrastructure, and budget. Here are the key factors our testing revealed matter most when making your decision.
Number of NVMe Slots and Storage Capacity
The number of M.2 slots directly determines your maximum all-flash capacity. Entry-level models like the DXP2800 offer two slots, which limits you to roughly 16TB of raw NVMe storage using current 8TB drives. Mid-range models with four slots can reach 32TB, while the Flashstor 12 Pro reaches an extraordinary 96TB or more. Consider not just your current storage needs but your anticipated growth over the product’s lifespan, typically three to five years.
Network Speed: 2.5GbE vs 10GbE
This is the most commonly overlooked factor in NVMe NAS purchasing decisions. NVMe SSDs can easily sustain read/write speeds of 3,000 MB/s or more, but a 1GbE network connection maxes out at 125 MB/s and a 2.5GbE connection at around 280 MB/s. To actually benefit from NVMe speeds inside a NAS, you need at least a 10GbE network infrastructure including a compatible switch, router, and network cards in your computers. If your existing network is built on 1GbE or 2.5GbE, the NVMe drives inside the NAS will still provide faster local access and snappier app performance, but you will not see the full speed advantage over the network.
Processor and RAM
The processor determines how many simultaneous tasks your NAS can handle and whether features like hardware-accelerated video transcoding, virtual machines, and Docker containers run smoothly. The Intel N100 in budget models handles basic NAS tasks well but shows limitations under heavy parallel workloads. The Intel Celeron N5105 found in most mid-range Asustor models provides a good balance of power efficiency and capability. The Intel Pentium Gold 8505 and Core i5 in UGREEN’s premium models deliver workstation-class performance for the most demanding scenarios. RAM expandability matters if you plan to run multiple services; models with DDR5 support and expansion slots give you more headroom for future needs.
Software Ecosystem and Operating System
Hardware specifications do not tell the full story. The NAS operating system determines how easily you can set up services, manage storage pools, and maintain the system over time. Synology’s DSM and QNAP’s QTS are widely regarded as the most polished platforms with the largest app ecosystems. UGREEN’s proprietary OS has improved significantly and offers an intuitive experience for beginners but has a smaller app catalog. Asustor’s ADM provides excellent hardware integration but occasionally requires more manual configuration than competitors.
Cooling and Thermal Management
NVMe SSDs generate more heat than SATA SSDs or HDDs when under sustained load, and thermal throttling can reduce performance or shorten drive lifespan. Our testing found that NAS models with dedicated NVMe thermal management, such as heat vents and direct airflow designs, maintained lower drive temperatures during extended stress tests. The UGREEN DXP4800 Plus and DXP480T Plus both showed elevated SSD compartment temperatures under sustained heavy writes, which is worth considering if you plan to run your NAS at maximum load continuously.
Budget Considerations
All-NVMe flash NAS storage devices cost significantly more per terabyte than traditional HDD-based NAS systems. A 2-bay HDD NAS with 20TB of storage might cost $400 total, while a comparable 2-bay NVMe NAS with 16TB of NVMe storage could cost $600 or more before adding the cost of the NVMe drives themselves. The performance premium is real, but so is the price premium. Evaluate honestly whether your use case justifies the investment: if you primarily access files over a 1GbE network and do not run virtual machines or transcoding workloads, the speed advantage of NVMe storage may never be fully realized in your environment.
Is an NVMe NAS worth it?
NVMe NAS is worth it if you need fast data access for video editing, virtual machines, gaming libraries, or applications where storage speed directly impacts productivity. If your network is limited to 1GbE or 2.5GbE and your workloads are basic file storage and streaming, the premium cost may not deliver proportional benefits. For professionals with 10GbE infrastructure and performance-sensitive workloads, the difference is substantial and justifies the investment.
Is NVMe suitable for NAS use?
NVMe is absolutely suitable for NAS use, and all-flash NAS systems have become increasingly popular in both consumer and enterprise markets. Modern NAS operating systems like Synology DSM, QNAP QTS, Asustor ADM, and UGREEN NAS OS all fully support NVMe drives as primary storage. The NVMe protocol provides lower latency and higher IOPS than SATA SSDs, making it ideal for virtual machine storage, databases, and applications that benefit from fast random access speeds.
What is the average lifespan of an NVMe SSD in a NAS?
Most NVMe SSDs are rated for between 300TBW and 1,200TBW written, depending on capacity and quality tier, with typical warranties covering 5 years. In a NAS environment with moderate write activity, a quality 2TB NVMe SSD could last 8-10 years before reaching its TBW limit. Enterprise-grade NVMe drives with higher endurance ratings will last longer under heavy write workloads. Most users will replace their NAS hardware long before they exhaust their NVMe drives.
Why is NVMe NAS more expensive than traditional NAS?
NVMe NAS devices cost more because NVMe SSDs themselves are more expensive per gigabyte than SATA SSDs or HDDs, and the NAS hardware requires more advanced PCIe lane management to support multiple NVMe slots simultaneously. Additionally, many all-flash NAS models include premium features like 10GbE networking, powerful Intel Core processors, and ECC memory support that further increase the hardware cost. The total system cost including drives can be 2-4x higher than an equivalent capacity HDD-based NAS.
Which NVMe NAS is best for TrueNAS Scale?
Most x86-based NAS systems with sufficient RAM can run TrueNAS Scale, but models with Intel or AMD processors, at least 8GB of RAM, and support for SATA or NVMe boot drives work best. The UGREEN DXP4800 Plus and Asustor Lockerstor 2 Gen2 are popular choices in the homelab community for TrueNAS Scale installations. Avoid models with ARM processors or limited RAM if you plan to run TrueNAS Scale with ZFS, as these require significant memory and CPU resources.
