Synology vs QNAP: which NAS should you buy?
By Devin Chua · Reviewed by Claire Bergeron · Updated Buy Synology for the most polished software (DSM), SHR flexible RAID and a low-maintenance experience. Buy QNAP for more hardware and flexibility — PCIe expansion for 10GbE, Intel CPUs with Quick Sync, and the option of ZFS via QuTS hero. Synology suits a set-and-forget home; QNAP suits a tinkerer who wants expandability or ZFS. QNAP has no SHR equivalent, so mixed drive sizes waste capacity there.
Synology vs QNAP, at a glance
| Synology | QNAP | |
|---|---|---|
| Software (OS) | DSM — cleaner, more consistent | QTS — feature-dense, wider apps |
| Flexible RAID | SHR (uses mixed drive sizes) | None (mixed sizes level down) |
| ZFS option | no | QuTS hero (checksums, snapshots) |
| Plex 4K transcode | Ryzen, no iGPU (software only) | Intel Quick Sync on most models |
| Expansion | fixed by model | PCIe slots (10GbE, NVMe, HBA) |
| Ease of use | simplest, most polished | more control, more fiddly |
| Best for | set-and-forget home | tinkerer, VMs, ZFS |
The verdict: which should you buy?
Software: Synology's polish vs QNAP's breadth
DSM is cleaner and more consistent; QTS is more feature-dense and occasionally more fiddly, with a wider app catalogue. For a household that wants to set it up once and forget it, Synology wins on polish. For a user who wants deep control, VMs and a virtualization station, QNAP offers more surface area.
Storage: SHR vs QuTS hero (ZFS)
Synology's SHR uses mixed drive sizes and grows gracefully. QNAP has no SHR equivalent — its 'flexible volumes' distribute space within a pool but do not rescue the surplus of mismatched drives, so mixed sizes level to the smallest. QNAP's counter is QuTS hero, which runs ZFS with checksums, snapshots and inline compression — a genuinely different, more data-integrity-focused platform. If you want ZFS on an appliance, QNAP is the mainstream route; if you run QuTS hero, size it with the RAID-Z calculator, not the RAID one.
Expansion and CPU
QNAP's PCIe slots make 10GbE, extra NVMe or an HBA an upgrade rather than a purchase decision, and its Intel CPUs bring Quick Sync for Plex. Synology's lineup is more fixed by model. For a NAS you expect to grow or repurpose, QNAP's expandability is the edge; for a fixed, dependable home unit, Synology's simplicity is.
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 Synology or QNAP better?
Synology for polished software, SHR and low maintenance; QNAP for hardware, PCIe expansion and ZFS via QuTS hero. Choose by whether you value a finished, simple appliance (Synology) or a flexible, expandable one (QNAP).
Does QNAP have SHR?
No. QNAP has no SHR equivalent, so mixed drive sizes waste capacity. Its answer is QuTS hero, a ZFS-based OS focused on data integrity rather than flexible sizing.
Can QNAP run ZFS?
Yes — install QuTS hero instead of QTS and the NAS runs ZFS, with checksums, snapshots and compression. Size a QuTS hero pool with the RAID-Z calculator, not the standard RAID one.
Devin Chua works out which drives, RAM and NVMe cache fit which NAS model at nasdrives.ca, and what the RAID choice means for usable capacity, checked against what is in stock on Amazon.ca.
