TL;DR
Thorsten Meyer AI’s 2026 comparison ranks the Synology DS223 as the best overall network attached storage device for private cloud use. UGREEN leads for expansion and demanding workloads, while BUFFALO offers simpler systems with hard drives included.
Synology’s two-bay DS223 has taken the best-overall position in a 2026 comparison of 10 network attached storage devices published by Thorsten Meyer AI. The report favors its balance of data-protection options, software usability and flexibility, while identifying UGREEN and BUFFALO systems as stronger choices for expansion or ready-to-use storage.
The report divides the recommendations by buyer need rather than naming one system as the fastest or largest in every category. It selects the BUFFALO LinkStation 710 4TB as the best plug-and-play option, the UGREEN DH4300 Plus for high-capacity media libraries and the UGREEN DH2300 for beginners. The DH4300 Plus has four bays, 8GB of memory and a claimed maximum capacity of 128TB.
Three BUFFALO LinkStation 210 configurations also appear: the 2TB model as the budget choice with storage included, the 4TB version as a ready-to-use budget system and the 6TB version as the higher-capacity plug-and-play pick. All use one drive bay, meaning they cannot mirror data across two disks and offer no internal bay-based expansion path.
The remaining selections target more specialized workloads. The Synology DS225+ is the report’s preferred media server because its Intel processor supports hardware-assisted transcoding. The UGREEN DXP2800, equipped with an Intel N100 processor and 8GB of DDR5 memory, is positioned for content creators. The two-bay Yxk Zero1 is selected for Docker experimentation, although the source flags reported customer-satisfaction concerns.
Two Bays Set the Baseline
The ranking reflects a basic divide in home and small-office storage. Single-bay systems reduce setup work and can cost less when a hard drive is included, but they cannot use disk mirroring to keep data available after one drive fails. Two- and four-bay systems provide more configuration choices, though buyers must often purchase drives separately.
The report also cautions that advertised capacity is not usable capacity when redundancy is enabled. Likewise, a 2.5GbE network port will not deliver its full benefit unless the router, switches, client devices and cabling support comparable speeds. These costs can change the value calculation beyond the NAS enclosure’s listed price.

Private Storage Choices Expand
NAS devices give households and small offices a central location for backups, shared documents and media while supporting remote access without making a public cloud service the primary storage location. The category now ranges from preconfigured single-drive appliances to diskless systems that can run containers, media servers and other self-hosted services.
The comparison places the Synology DS223 between those extremes. Its two bays permit mirrored storage or separate volumes, while Synology’s software is described as more approachable than many enthusiast-focused platforms. Its limitation is physical growth: four-bay hardware offers more expansion room for archives that are expected to increase steadily.

Testing Gaps Limit Comparisons
The supplied material does not provide standardized benchmark results, measured power consumption or current prices, so it is not possible to verify which device delivers the highest sustained transfer speed or lowest total ownership cost. Some specifications are presented as manufacturer claims rather than independent measurements.
It is also unclear how the report weighted security-update policies, application support and long-term reliability. Availability may vary by market, and the source does not establish whether every listed model will remain widely stocked throughout 2026.

Buyers Must Price Complete Systems
Prospective buyers should next compare current enclosure and drive prices, confirm application compatibility and calculate capacity after the chosen redundancy setup. They should also verify whether their network supports 1GbE or 2.5GbE speeds. The ranking may change as prices, software support and product availability shift during 2026.

Key Questions
Which NAS ranks best overall for private cloud storage in 2026?
The report selects the Synology DS223 because its two-bay design and management software provide a broad balance for household and small-office use.
Which model offers the most expansion room?
The UGREEN DH4300 Plus has four drive bays and a claimed maximum capacity of up to 128TB, giving it the most physical growth capacity in the comparison.
Which NAS models include hard drives?
The listed BUFFALO LinkStation 710 4TB and LinkStation 210 models in 2TB, 4TB and 6TB capacities include storage. Several Synology and UGREEN recommendations are diskless.
Does a two-bay NAS replace a separate backup?
No. Disk mirroring protects against one drive failure, but it does not protect against deletion, malware, theft or damage to the entire device. Important files still need a separate backup copy.
Is 2.5GbE networking worth paying for?
It can improve transfers for large files, but only when the full network path supports 2.5GbE. Systems limited elsewhere to 1GbE will not receive the full speed benefit.
