A 2026 comparison names the Synology DS223 the best overall NAS among 10 devices, with UGREEN and BUFFALO models leading other buyer categories. The supplied evidence supports their storage, networking and media features, but does not establish that AI has become a standard NAS capability.
A 2026 comparison of 10 network-attached storage devices has named the Synology DS223 the best overall choice for households and small offices, citing its two drive bays and accessible software. The report also identifies stronger options for expansion, media work and simple setup, but provides no confirmed evidence that AI features are yet the defining reason to buy a private NAS.
The comparison places the UGREEN DH4300 Plus at the front for high-capacity media libraries. Its four bays, 8GB of LPDDR4X memory, claimed support for up to 128TB and 2.5GbE networking offer more growth room than two-bay models, although faster transfers depend on compatible network equipment.
For buyers seeking storage with fewer setup decisions, the report recommends the BUFFALO LinkStation 710 4TB as its plug-and-play pick. The LinkStation 210 range also includes drives in 2TB, 4TB and 6TB versions, but each uses one bay, preventing mirrored protection across two disks.
The remaining selections target narrower needs: the UGREEN DH2300 for beginners, the Synology DS225+ for hardware-assisted media transcoding, the Yxk Zero1 for Docker experimentation and the UGREEN DXP2800 for content creators. The list is completed by three LinkStation 210 capacities, producing 10 entries across four brands.
Private Control Drives NAS Demand
A NAS gives users local control over backups and shared files while supporting private remote access and media libraries. That can reduce dependence on recurring cloud-storage plans, but local ownership also transfers responsibility for drive maintenance, security and off-site backup to the buyer.
The AI question matters because private models can involve sensitive documents and large data sets. Some listed hardware may support self-hosted software, yet the report confirms only features such as Docker support, Intel processors and media transcoding. It does not show dedicated AI accelerators, model benchmarks or integrated AI services, so private storage is confirmed; private AI performance is not.

Capacity and Redundancy Shape Choices
The comparison reflects a long-standing division in the NAS market. Diskless systems, including several Synology and UGREEN models, let buyers choose their drives and redundancy setup but require a separate storage budget. Drive-included BUFFALO systems are easier to start using, though their single-bay design limits protection and expansion.
Drive count also changes what advertised capacity means. The two-bay DS223 can use mirroring to preserve access after one drive fails, at the cost of usable capacity. The four-bay DH4300 Plus provides broader configuration options, while a one-bay LinkStation cannot create internal mirrored redundancy. None of these arrangements replaces a separate backup.
“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 Performance Evidence Is Missing
It is not yet clear which, if any, of these devices can run demanding AI models at useful speeds. The source provides no AI inference tests, model compatibility results or power measurements, and it does not confirm dedicated neural-processing hardware. Describing the lineup as an AI-ready private cloud would go beyond the available evidence.
Several other points also lack supporting detail, including current prices, full warranty coverage for every model and independently verified reliability data. The Yxk Zero1 is described as having low reported customer satisfaction, but the supplied material gives no sample size or methodology. The DH4300 Plus capacity figure is also a manufacturer-supported maximum, not included storage.
Benchmarks Will Test AI Claims
Buyers should watch for independent AI workload benchmarks, software-support commitments and confirmed pricing before treating AI as a deciding feature. Nearer-term decisions remain more concrete: choose the required bay count, redundancy level, included capacity and network speed, then budget for compatible drives and an off-site backup.
Key Questions
Which NAS ranks best overall for 2026?
The report selects the Synology DS223 because its two-bay layout and approachable software balance flexibility, drive-failure protection options and ease of management.
Which model offers the most expansion room?
The UGREEN DH4300 Plus leads this group with four drive bays and claimed support for up to 128TB. Drives appear to require a separate purchase.
Are these NAS devices confirmed to run private AI?
No broad AI capability is confirmed by the supplied report. It documents Docker support and Intel-based hardware on selected models, but includes no AI benchmarks or dedicated accelerator specifications.
Does RAID or disk mirroring replace a backup?
No. Mirroring can maintain access after a single drive failure, but it does not protect against deletion, malware, theft or device damage. Users still need a separate off-site or cloud backup.
Who should choose a drive-included NAS?
A BUFFALO LinkStation may suit buyers who value quick setup and known starting capacity. The tradeoff is that the listed single-bay models cannot mirror data internally or expand across additional bays.
