Synology vs UGREEN: which NAS should you buy?

Portrait of Devin ChuaBy Devin Chua · Reviewed by Claire Bergeron · Updated · Prices checked
In short

Buy Synology for the best software (DSM), SHR flexible RAID and ECC on the Plus models: the polished, low-maintenance choice. Buy UGREEN for more hardware per dollar: faster Intel CPUs with Quick Sync for Plex, more RAM headroom and 10GbE at prices Synology cannot match, at the cost of younger software and no SHR. For a set-and-forget home cloud, Synology; for a powerful Plex-and-containers box on a budget, UGREEN.

Synology vs UGREEN, at a glance

Software (OS)DSM, most polished, mature appsUGOS Pro: capable but younger
Flexible RAIDSHR (uses mixed drive sizes)None (mixed sizes waste capacity)
Plex 4K transcodeRyzen, no iGPU (software only)Intel Quick Sync (hardware)

ECC memoryyes, on Plus modelsno
App ecosystemPhotos, Drive, Surveillance Stationbasic first-party apps + Docker
Hardware per dollarpremiummore machine for the money

Both are open on drive choice today: UGREEN mandates no brand; Synology reversed its 2025 hard-drive lock in DSM 7.3 (M.2 NVMe still needs a listed drive).

The verdict: which should you buy?

Choose
Synology
you want the most polished software and app suite, SHR to mix and grow drive sizes, ECC, and a NAS you set up once and forget. You mostly direct-play Plex rather than transcode.
Choose
UGREEN
you want Plex hardware transcoding (Quick Sync), more CPU, RAM and 10GbE per dollar, and you are happy to trade the most mature software and SHR for hardware value and a bit more tinkering.

Software and RAID: Synology's edge

DSM is the most mature NAS operating system, and its apps (Synology Photos, Drive, Surveillance Station) are genuinely good and have no turnkey equal. Synology also has SHR, which uses mixed drive sizes and lets you grow the array one larger drive at a time; UGOS Pro has no equivalent, so on UGREEN mixed sizes waste capacity. If you value finished software and flexible storage, Synology leads.

Hardware per dollar: UGREEN's edge

UGREEN's NASync line gives you more machine for the money: Intel N100, Pentium or Core-i CPUs with Quick Sync (Synology's Plus models use embedded Ryzens with no iGPU, so they cannot hardware-transcode Plex), more RAM headroom, NVMe slots and even 10GbE on models priced against Synology's 2.5GbE units. For Plex transcoding, containers and raw throughput, UGREEN is often the better value.

The drive policy, and the trade-off in short

Both are open enough today: UGREEN mandates no drive brand, and Synology reversed its 2025 hard-drive restriction in DSM 7.3 (M.2 NVMe still needs a listed drive on Synology). So drive choice is not the deciding factor now.

The honest summary: Synology sells you polish, longevity and SHR; UGREEN sells you hardware and Plex transcoding per dollar. Neither is wrong: match it to whether you want a finished appliance or a powerful box you will tinker with. Size either with the Synology or UGREEN calculator.

Buying in Canada

Canadians cross-shop Amazon.ca, Best Buy Canada, Canada Computers, Newegg.ca and Memory Express; the cheapest SKU moves between them, and we track Amazon.ca live in CAD as the baseline. It is worth a two-minute check across those before you buy a drive or a NAS.

On importing from Amazon.com: it rarely beats a local CAD price once you add exchange, any duty, brokerage and the harder path to a warranty claim or return. The exchange rate is not a penalty: the honest point is total landed cost plus how much easier a return or RMA is when you bought it in Canada. For a drive that will run 24/7 for years, local warranty support is worth real money.

Frequently asked questions

Is UGREEN or Synology better?

Synology for software, SHR and low-maintenance longevity; UGREEN for more CPU, RAM and 10GbE per dollar and for Plex hardware transcoding (Synology's Ryzen Plus models have no iGPU). Choose by whether you want a finished appliance or hardware value.

Can Synology hardware-transcode Plex?

The current Ryzen-based Plus models (DS925+, DS923+) cannot: they have no integrated GPU, so Plex transcodes in software. Intel-based UGREEN models (N100 and up) have Quick Sync and hardware-transcode 4K. That is a key UGREEN advantage for Plex.

Does UGREEN have SHR like Synology?

No. UGOS Pro has no SHR equivalent, so mixed drive sizes waste capacity on UGREEN. Synology's SHR (and TerraMaster's TRAID) are the flexible-RAID options in this class.
