6 Best NAS Devices for Home in 2026 (Diskless Picks Compared)

On paper the DS223j is the weakest device here: two bays, an ARM processor, a gigabit port. It is still the right recommendation for most people, because with a NAS you are buying an operating system that has to keep your data safe for a decade, and Synology’s DSM is the best one.

DSM is genuinely mature. Setup is guided rather than technical, the interface makes sense to someone who has never administered a server, and the documentation is extensive. More importantly, Synology ships security updates for its hardware for years after release. A NAS is internet connected and holds everything you own; an abandoned device with unpatched vulnerabilities is a serious liability, and smaller vendors have a patchy record here.

The feature set covers what home users actually need: automated backup for Macs, PCs and mobile devices to multiple destinations, secure file sharing with granular permissions, and Surveillance Station for recording IP cameras with remote viewing.

Two bays in RAID 1 gives you a mirrored copy, so a single drive failure costs you nothing. With two 8TB drives that is 8TB usable.

The limitations are real. The ARM chip cannot hardware transcode, so this is not the Plex machine. Gigabit networking caps transfers around 110 MB/s. And two bays means expanding later requires replacing drives rather than adding them.

Buy it for reliability and software, not for specifications.

If the NAS is going to serve media, this is the one, because the Intel x86 quad core does hardware level 4K H.265 decoding that ARM units cannot.

In practice that means Plex, Emby or Jellyfin can transcode a 4K film down for a phone or an older TV in real time, using dedicated silicon rather than struggling in software. It is the single specification that separates a working media server from a frustrating one, and at $254.99 this is the cheapest route to it here.

The 2.5GbE port complements that, moving files at roughly 280 MB/s against gigabit’s 110. For anyone editing video off network storage or moving large media libraries, that is a genuine time difference.

Noise is the underrated feature. TerraMaster rates it at 19 dB, which is close to silent. A NAS runs continuously, and if it lives in a bedroom, a study or a living room, noise is the reason people end up switching it off. Nothing else here publishes a figure this low.

TRAID is TerraMaster’s flexible array system, which they claim saves around 30 percent more usable space than traditional RAID while keeping redundancy. Capacity goes to 60TB across two 30TB bays.

Push Lock trays let you fit drives without tools, and the TNAS mobile app can complete initial setup without a computer.

The trade against Synology is software maturity. TOS is capable and improving, but DSM has a longer track record and a larger community when something goes wrong.

Four bays for $262.99 is the value proposition here, and four bays change what a NAS can do.

With four drives you can run RAID 5, which gives you the capacity of three drives with the redundancy of one. Four 8TB drives in RAID 5 yield 24TB usable while surviving any single drive failure. In a two bay unit running RAID 1, the same four drives would give you 16TB. The efficiency improves as you add bays.

The feature worth highlighting is Btrfs snapshots with WORM. Snapshots let you restore your data to an earlier point in time, which is the practical defence against both accidental deletion and ransomware. WORM makes selected data immutable, so it cannot be encrypted or overwritten even by an attacker with access. That combination is genuinely enterprise grade and unusual at this price.

The Realtek RTD1619B quad core at 1.7GHz with 1GB DDR4 handles backups and file serving efficiently at low power. It is an ARM class chip, so hardware transcoding is not its strength despite the listing mentioning 4K playback. Direct streaming of files a device can already play works fine; transcoding does not.

A 2.5GbE port and three USB 3.0 ports round it out.

The 1GB of RAM is the real constraint. It is adequate for storage and backup, and thin for running several applications at once.

UGREEN built this specifically for people moving from cloud storage or external drives, and it shows in what it does and does not try to do.

The AI photo organisation is the standout feature for a family. It tags faces, locations, text and objects automatically, so you can search your library for a person or a place rather than scrolling through years of camera roll. It also finds duplicate and near duplicate photos and offers to remove them, which on a decade of phone backups reclaims a genuinely useful amount of space.

4GB of RAM is four times what the Asustor offers, and it is why the photo indexing and search feel responsive rather than sluggish.

Security is unusually well documented: RAID modes, two factor authentication, permission controls and encrypted transfers, with TRUSTe certification and, UGREEN claims, the first NAS certified by TÜV SÜD against ETSI EN 303 645. For a device holding your family’s photos and exposed to the internet, that is worth something.

UGREEN is explicit about the limitation: the DH2300 does not support Docker or virtual machines. That is a deliberate simplification for the beginner market, and it means you cannot self host applications on it. If you want Home Assistant or a Plex server, this is the wrong model and the DH4300 Plus is the one to look at.

Gigabit networking at up to 125 MB/s, capacity to 64TB across two bays.

This is the DH2300 with the constraints removed: four bays instead of two, 8GB of RAM instead of 4, a 2.5GbE port instead of gigabit, and Docker support.

Docker is what turns a NAS from storage into a small server. With it you can run Pi-hole for network wide ad blocking, Home Assistant for smart home control, a Jellyfin media server, or a personal password manager. UGREEN notes that virtual machines are still not supported, so this sits between the beginner DH2300 and the full DXP series.

8GB of RAM is what makes several containers plus photo indexing practical simultaneously. It is the highest of any sub $400 NAS here.

Transfers run at roughly 333 MB/s over 2.5GbE, quoted as a 1GB file in about three seconds.

A 4K HDMI output means the NAS can drive a television directly, playing media without a separate streaming box in the loop.

The AI photo features carry over from the DH2300, with semantic search, recognition of people, objects and pets, and duplicate removal. On a family library that is the feature people use daily.

Setup includes NFC pairing, and access works across Windows, macOS, Android, iOS, browsers and smart TVs.

At $373.99 it is $111 more than the four bay Asustor. You are paying for eight times the RAM, Docker, HDMI output and the photo software, which for a family is a reasonable trade.

This is a different class of machine, and the case for it is specific: editing large video files directly from network storage.

Dual 10GbE networking is the reason. At 10 gigabit you move roughly 1,100 MB/s, which is faster than many internal SATA SSDs. That is the threshold at which editing 4K footage off the NAS feels like editing from a local drive, with no copying step at all. Two ports allow link aggregation or a separate high speed path to an edit workstation.

The AMD Ryzen Embedded R2514 with four cores, eight threads and boost to 3.70GHz is a proper desktop class processor, with 8GB DDR4 expandable to 64GB. It runs Docker containers and full virtual machines simultaneously, which the DH series cannot.

Capacity reaches 144TB: four SATA bays up to 32TB each, with two of those bays also accepting U.2 NVMe SSDs, plus two M.2 slots for another 16TB.

Two practical touches for creators. A built in SD card slot imports footage straight from a camera without a reader or a computer. And the Surveillance Center turns the NAS into an ONVIF and RTSP camera recorder with live multi view, PTZ control and timeline playback, all stored locally with no subscription.

Connectivity includes USB-A and USB-C at 10 Gbps, USB 2.0 and 4K HDMI.

At $559.99 before drives this is a serious purchase. Buy it if you edit video or run virtual machines. For storage and backup, the Synology at a third of the price does that job.
