Synology vs UGREEN vs DIY NAS in 2026

The three philosophies

These aren't just three brands — they're three fundamentally different approaches to home storage, and choosing the wrong one will frustrate you for years.

Synology is the appliance approach. You buy a box, install drives, click through a setup wizard, and it works. Synology controls the hardware, the software (DSM), the apps, and the upgrade path. You give up flexibility and pay a premium; in return you get the closest thing to "it just works" that exists in self-hosted storage.

UGREEN (and TerraMaster, Asustor, QNAP) is the appliance-with-options approach. The hardware is competitive with Synology and often cheaper. You can run their first-party OS, or you can wipe it and install TrueNAS, Unraid, Proxmox, or plain Linux. Best of both worlds, with the small cost of slightly less polished first-party software.

DIY is the build-your-own approach. You pick a case, motherboard, CPU, RAM, drives, and install whatever OS you want. Maximum capacity, maximum flexibility, lowest cost-per-TB at scale, and complete responsibility. If something breaks, the on-call rotation is you.

Head-to-head: the numbers

Here's how comparable 4-bay configurations stack up. Each is the cheapest option from each brand that supports four drives, RAID 5/6, and modern features like SSD caching.

Setup	CPU	RAM	Idle	Load	Hardware $
Synology DS423+	Intel J4125	2GB (max 6GB)	18W	36W	$499
Synology DS923+	Ryzen R1600	4GB (max 32GB)	24W	48W	$599
UGREEN DXP4800 Plus	Intel Pentium 8505	8GB (max 64GB)	12W	38W	$549
TerraMaster F4-424	Intel N95	8GB (max 32GB)	13W	32W	$429
DIY: Jonsbo N3 build	Intel N100	16GB (max 32GB)	11W	28W	$485

The numbers tell a story: Synology is the most expensive and the highest-idle option in this comparison. The DS923+ idles at 24W — twice what a comparable UGREEN unit pulls. Over five years at $0.17/kWh, that 12W difference costs you about $90 in electricity. Not enough to matter on its own, but it's emblematic — you're paying more upfront and more to run it.

Synology: The polished appliance

Synology's pitch has always been the software, and it's still true. DiskStation Manager (DSM) is the most polished NAS operating system on the market by a wide margin. Hyper Backup is genuinely excellent. Synology Photos is the only first-party Google Photos alternative that I can recommend without caveats. The apps work, the updates are reliable, and the experience is what people mean when they say "it just works."

The problems are real, though. Drive lock-in. Starting with the 2024 Plus-series, Synology has been pushing drive compatibility lists that effectively require Synology-branded HDDs and SSDs in some models. These drives are rebadged and substantially more expensive than equivalent WD Red or Seagate IronWolf drives. If you put a non-listed drive in a recent DS923+ or DS1522+, you'll see warnings; in some cases, certain features are disabled entirely.

Hardware stagnation. The DS423+ ships in 2026 with the same Intel J4125 from 2019. The CPU is fine for basic file serving and Plex direct-play, but it's slower than every comparable competitor and won't HW-transcode 4K HEVC in Plex. Synology's plus-series upgrades have been minor for three generations.

Price. A diskless DS923+ is $599. A diskless UGREEN DXP4800 Plus with a faster CPU, more RAM, and lower idle wattage is $549. You're paying a 10–20% premium across the line for the DSM software.

Buy Synology if: you want the best NAS software experience, you don't mind paying a premium, your use case is mostly file storage and photos rather than running services, or you're setting this up for a non-technical family member who'll never want to touch it.

UGREEN: The 2024–2026 surprise

UGREEN entered the NAS market in 2024 with the DXP series, and after some early software roughness, they've become the brand to beat. The hardware is genuinely excellent — modern Intel CPUs (N100, Pentium 8505, i5-1235U at the higher end), proper SODIMM expansion (not soldered), M.2 NVMe slots in addition to drive bays, and 2.5GbE or 10GbE depending on the model. Idle wattage is the lowest in this class.

UGOS Pro, the included operating system, has matured fast. It now does everything most users need: RAID 1/5/6/10 and SHR-equivalent, snapshots, scheduled backups, Docker container management, photo backup with face recognition, remote access via UGREEN Link, and a reasonable mobile app. It is not as polished as DSM. The translations occasionally feel off. Some advanced features lag behind Synology by a release or two. But for 90% of NAS use cases, it's good enough.

The killer feature, though, is that you don't have to use it. UGREEN hardware accepts any operating system. Many homelabbers buy a UGREEN unit, immediately install TrueNAS Scale or Unraid, and use UGREEN purely as the hardware vendor — getting the modern CPU and good build quality at a price point Synology doesn't touch.

Buy UGREEN if: you want modern hardware at a fair price, you care about idle wattage, you want the option to swap operating systems later, or you're comfortable with software that's "good but not Apple-polished."

DIY: TrueNAS Scale or Unraid on your own hardware

Building your own NAS used to be a clear win on price for anything beyond two bays. In 2026, the math is closer — UGREEN and TerraMaster have squeezed the price advantage thin — but DIY still wins for two specific scenarios: very small (single mini PC + USB enclosure for under $400) or very large (8+ bays where retail NAS prices balloon).

The mid-range sweet spot for DIY is the Jonsbo N3 build: a Jonsbo N3 case (8 bays, around $200), a mini-ITX motherboard with an Intel N100 CPU built in (around $160), 16GB DDR4 SODIMM ($35), a 500GB NVMe boot drive ($45), and a low-watt SFX power supply ($45). About $485 before drives, idles at 11W, and gives you 8 bays for less than a 4-bay Synology.

You install TrueNAS Scale or Unraid yourself. TrueNAS is the better choice if you want ZFS and don't need flexibility on drive sizes. Unraid is the better choice if you want to mix drive sizes (its parity model handles this elegantly) or if you want a more app-store-like experience for adding services.

The cost of DIY is your time. You're buying parts that have to fit together, you're installing the OS yourself, and when something goes wrong, there's no support number to call. For homelabbers who already enjoy this kind of thing, that's a feature, not a bug.

Build DIY if: you want 8+ bays, you want the absolute lowest idle wattage, you want to mix drive sizes (Unraid), you enjoy the build process, or you want TrueNAS Scale or Unraid specifically.

The five-year cost of ownership

Here's what each setup actually costs over five years, including the hardware, four 12TB drives ($720), and electricity at $0.17/kWh. Numbers are approximate but realistic.

Setup	Hardware	Drives	Power (5yr)	5-year total
Synology DS923+	$599	$720	$179	$1,498
UGREEN DXP4800+	$549	$720	$89	$1,358
TerraMaster F4-424	$429	$720	$97	$1,246
DIY Jonsbo N3	$485	$720	$82	$1,287

Even ignoring software differences, Synology costs $200–$250 more over five years than the alternatives. That's a real premium for DSM, and whether it's worth it depends entirely on how much you value the software polish.

Our pick

For most readers in 2026, we recommend the UGREEN DXP4800 Plus. It's the right balance of hardware quality, idle power, price, and software maturity. You can run UGOS Pro out of the box and be productive in an hour, or you can wipe it and install TrueNAS Scale if you want more control. You're not locked in either direction.

For non-technical users who want a NAS to "just work" forever, we still recommend Synology. The premium is real, but so is the value of software that doesn't surprise you.

For 8+ bays, very specific workloads, or anyone who genuinely enjoys the build, we recommend DIY with TrueNAS Scale or Unraid. The price advantage at scale and the flexibility advantage at every scale are real.

Whichever path you pick, use our NAS Capacity Calculator to plan your RAID level and our Power Calculator to estimate the running cost. Both will save you from at least one expensive surprise.
