TL;DR
A Thorsten Meyer AI comparison ranks the Synology DS223 as its best overall NAS, with UGREEN and BUFFALO models recommended for expansion, performance, or simple setup. The supplied findings document storage, networking, media, and software features but do not establish which devices offer AI functions.
A 2026 network-attached storage comparison from Thorsten Meyer AI has named the two-bay Synology DS223 its best overall choice for households and small offices, while directing buyers with larger libraries toward the four-bay UGREEN DH4300 Plus. The findings offer a broad private-storage shortlist, but the supplied material does not confirm the AI capabilities suggested by the report’s theme.
The report places the Synology DS223 first because its two drive bays, data-protection options, and accessible management software provide what the publisher describes as a balanced package. It is sold without hard drives, giving owners control over capacity and drive selection but adding to the initial purchase cost.
For larger archives, the comparison favors the UGREEN DH4300 Plus, listing four bays, 8GB of memory, a stated capacity of up to 128TB, and 2.5-gigabit Ethernet. Those specifications give it more expansion room than two-bay systems, although faster transfers depend on compatible network equipment. The report does not provide independent performance testing for the listed transfer capabilities.
BUFFALO LinkStation 210 models are presented as simpler alternatives because they include a hard drive in 2TB, 4TB, or 6TB configurations. Their single-bay design prevents disk mirroring and offers no internal expansion route. The report also identifies the Synology DS225+ for hardware-assisted media transcoding and the UGREEN DXP2800 for more demanding file-management work.
Local Storage Choices Split Sharply
The rankings show that buying a NAS remains a choice between easy initial setup and longer-term flexibility. A drive-inclusive BUFFALO system may suit a buyer seeking basic backups immediately, while diskless Synology and UGREEN devices allow tailored capacity, redundancy, and future drive replacement.
The distinction matters because a NAS can become the central repository for personal files, device backups, and media. Two or four bays can support mirrored or more advanced storage arrangements, reducing disruption after a drive failure. That protection does not replace an independent backup, since theft, accidental deletion, malware, or device-wide failure can still affect locally stored data.

From Simple Backups to Self-Hosting
The comparison covers 10 devices across four brands, spanning ready-to-use single-bay appliances and diskless systems designed for additional services. Its recommendations divide the market by buyer type rather than naming one device as the fastest or most capable in every category.
The Yxk Zero1, for example, receives a niche recommendation for Docker experimentation, but the publisher cites reported customer-satisfaction concerns. The UGREEN DXP2800 is positioned for creators through its Intel N100 processor and 8GB of DDR5 memory, while the DS225+ receives the premium media-server role. These labels are the publisher’s evaluations, not manufacturer-independent certifications.
“Synology DS223 takes the best-overall position because its two-bay layout and polished software are more broadly useful than the simpler single-bay BUFFALO models.”

AI Claims Lack Supporting Detail
The largest unresolved issue is the AI-infused description. The supplied comparison details processors, memory, drive bays, Docker support, networking, remote access, and media transcoding, but it identifies no specific AI models, local inference features, or automated AI tools for the recommended systems. Readers cannot determine from this material whether AI functions run on each device, depend on cloud services, or are absent.
The source also does not provide current prices, controlled benchmarks, noise measurements, power consumption, or long-term reliability data. Some maximum-capacity and performance figures appear to be manufacturer specifications. Exact drive compatibility, software support periods, and regional availability remain unclear and should be checked against current manufacturer documentation before purchase.
Testing Must Validate the Rankings
The next useful step will be model-by-model testing of transfer speeds, backup recovery, remote access, media playback, software maintenance, and any claimed AI functions. Testing should state the drive configuration and network hardware, since those variables can materially change results.
Buyers can meanwhile narrow the list by deciding how many drive bays they need, whether disks must be included, and whether their network supports 2.5GbE transfers. Final selection should follow checks of drive cost, compatibility, warranty coverage, and update policy for the exact model and region.
Key Questions
Which NAS did the report rank best overall?
The report selected the Synology DS223 because its two-bay design and management software offer a broad balance for home and small-office storage. Drives are sold separately.
Which model offers the most expansion room?
The UGREEN DH4300 Plus has four drive bays and a stated maximum capacity of up to 128TB. Actual usable capacity depends on installed drives, storage configuration, and filesystem overhead.
Are these NAS devices confirmed to include AI features?
No specific on-device AI features are documented in the supplied material. The comparison supports claims about storage, networking, Docker, and media processing, but the AI framing remains unverified.
Do single-bay BUFFALO models protect against drive failure?
The listed LinkStation 210 models contain one drive bay, so they cannot mirror data across two internal disks. Owners still need a separate backup destination for stronger protection.
Will a 2.5GbE NAS always transfer files faster?
No. A 2.5GbE connection provides a higher networking ceiling only when the router or switch, client computer, cabling, drives, and workload can support it. A 1GbE component can limit the full path.
