QNAP TS-264 2-Bay NAS
The QNAP TS-264 is a $500 2-bay NAS with an Intel Celeron N5095 quad-core (Quick Sync), 8GB DDR4 standard, two M.2 NVMe slots, a 2.5GbE port, and HDMI 2.0 4K output. It is the hardware-per-dollar winner among 2-bay units — the question is whether you want QTS instead of DSM.
Best hardware in a 2-bay NAS at this price — Quick Sync transcoding plus 2.5GbE makes it the Plex enthusiast's pick if you can stomach QTS.
Where to Buy
Pros
- Intel Celeron N5095 with Quick Sync handles 4K HEVC transcoding effortlessly
- 8GB DDR4 standard (expandable to 16GB) — twice the DS224+'s baseline
- 2.5GbE port pushes ~280MB/s — actually faster than 2-drive RAID 1 reads
- Two M.2 2280 NVMe slots for cache or storage tiering
- HDMI 2.0 4K output for direct media playback or local console use
Cons
- QNAP has had high-profile ransomware incidents (Deadbolt 2022, Qlocker 2021) — security depends on diligent updates and not exposing QTS to the internet
- QTS UI is more cluttered and less polished than Synology DSM
- Only one 2.5GbE port — competitors offer two for link aggregation
- QTS app ecosystem is huge but quality varies; some QNAP-developed apps are abandoned
- HD Player app for HDMI playback is buggy compared to Plex/Jellyfin via Container Station
Hardware — Where the TS-264 Earns Its Recommendation
The Intel Celeron N5095 is a 10nm Jasper Lake quad-core launched in 2021, with a 2.0GHz base and 2.9GHz burst, a 15W TDP, and Intel UHD Graphics with full Quick Sync support. Single-thread performance is roughly 25% faster than the J4125 in the Synology DS224+, and multi-thread is similar (both are quad-core, no hyperthreading). The differentiator is the GPU — UHD Graphics on Jasper Lake added 4K HEVC 10-bit decode, AV1 decode (limited), and improved H.264 encode quality. For Plex, this means smoother 4K HDR transcodes with less artifacting.
8GB DDR4 ships in a single SO-DIMM slot, with one open slot for expansion to 16GB total. QNAP uses standard DDR4-2933 SO-DIMM modules and does not enforce a vendor whitelist — any Crucial, Kingston, or Samsung 8GB SO-DIMM works. This is a meaningful contrast with Synology's increasingly aggressive RAM policies. 8GB is enough for QTS plus 4-5 containers; 16GB is comfortable for Immich's facial recognition workloads or running ML-based photo apps.
The two M.2 2280 NVMe slots are PCIe 3.0 x1 each — modest bandwidth (~1GB/s per slot) but enough for cache or tiered storage. QNAP allows ANY M.2 NVMe SSD in these slots without firmware policy walls. A pair of $40 256GB SSDs gives you SSD cache that meaningfully accelerates SMB workloads, especially for the small-file traffic that dominates household NAS usage (photo thumbnails, document opens, library scans).
QTS 5.1 — Powerful, Cluttered, and Improving
QTS 5.1 is QNAP's NAS operating system — Linux underneath, web UI on top. Functionally it is feature-equivalent to DSM: SMB/NFS file shares, snapshots (on QuTS hero with ZFS), Container Station for Docker, Multimedia Console for Plex/Jellyfin/native HD Player, Hybrid Backup Sync for cloud backup, Hyper Data Protector for VMs. QNAP has also been pushing QuTS hero, their ZFS-based variant, which adds end-to-end checksums and inline deduplication on units with 4GB+ RAM (the TS-264 qualifies).
The UI is the recurring complaint. Where DSM has a clear left-hand main menu and consistent right-side panels, QTS uses a desktop metaphor with floating windows and notifications that stack up. Power users love the configurability; new users get overwhelmed. App search inside the UI is also weaker — QNAP's App Center has thousands of packages but discovery is hit-or-miss compared to Synology's curated package center.
The security story is the bigger asterisk. QNAP suffered the Deadbolt ransomware campaign in 2022 (~10K units encrypted), the Qlocker campaign in 2021 (~7K units), and several CVE-9.0+ vulnerabilities in subsequent years. The pattern is consistent: QTS units exposed to the internet via UPnP or manual port forwards get popped. The fix is straightforward — never expose QTS web UI to the internet, only access remotely via myQNAPcloud, Tailscale, or a VPN — but it requires ongoing diligence that some buyers are not prepared for.
Networking and HDMI — The Niche Wins
The single 2.5GbE port is the hidden value of the TS-264. At ~280MB/s peak throughput, it is faster than the sustained read speed of two 7200rpm HDDs in RAID 1 (~200MB/s). With NVMe cache, sequential reads hit the network ceiling at full 2.5GbE. Real-world impact: a 5GB video file copies in 18 seconds instead of 50 over gigabit — significant for video editing or backup workflows. The TS-264 only has one 2.5GbE port (no link aggregation possible across multi-gig), but for single-user workloads that is enough.
The HDMI 2.0 output is QNAP's distinctive feature. Plug the NAS into a TV and it boots into HD Station — QNAP's media playback environment with native players for video, music, and photos. The reality is mixed: HD Player handles MKV files with HEVC well, but subtitle support is buggy, audio passthrough is inconsistent, and the remote-control app feels dated. Most users who care about media playback will run Plex or Jellyfin in Container Station and stream to a Chromecast/Roku/Apple TV anyway. The HDMI port is more useful as a recovery console — if QTS becomes unreachable over the network, you can plug in a keyboard and HDMI display to troubleshoot.
The lack of a second 2.5GbE port is the one networking gap. Competitors like the Ugreen DXP4800 Plus offer 10GbE plus 2.5GbE, and even small TerraMaster units offer dual 2.5GbE for failover. The TS-264's single 2.5GbE plus single 1GbE setup means no link aggregation between the two — they have to be on different subnets or used independently.
Common Gotchas
Never expose QTS to the internet. The Deadbolt ransomware in 2022 and Qlocker in 2021 both targeted QTS units with port-forwarded web UIs. Use myQNAPcloud (QNAP's cloud relay), Tailscale, or a proper VPN for remote access. Disable UPnP on your router. Keep auto-updates enabled on QTS. The hardware is fine; the threat model is QTS-on-the-public-internet.
The QTS app ecosystem includes abandoned packages. QNAP's App Center has hundreds of apps, but some QNAP-developed apps (older photo, music, and video stations) are no longer maintained. Stick to actively maintained apps: Container Station for Docker, Multimedia Console, Hybrid Backup Sync, QuTS hero (if you want ZFS). Third-party Plex/Jellyfin/Immich containers are more reliable than QNAP's own media apps.
HD Player on the HDMI port is unreliable for serious media playback. Subtitle handling, audio passthrough, and 4K HDR all have rough edges compared to Plex/Jellyfin running in Docker. If you bought the TS-264 for the HDMI output, be prepared for some debugging — or just use it as a recovery console and run Plex over the network.
QTS notifications accumulate aggressively. Every drive scrub, container update, package release, and cloud backup completion fires a notification. Disable notifications you do not care about in the Notification Center settings or the notification panel becomes useless. New users often miss this and assume their NAS is broken because of the alert volume.
M.2 SSDs in the bottom-mounted slots can run hot. The M.2 slots are inside the chassis with limited airflow. Generic NVMe SSDs without heatsinks can throttle under sustained writes. Use SSDs with low-profile heatsinks (Samsung 990 EVO, WD SN770, Crucial P3 Plus all work) and check temperatures after sustained workloads.

Who Should Buy This
The N5095's Quick Sync handles 4K HEVC, AV1 decode, and H.264 encode in hardware. Three concurrent 4K direct-play streams or two transcodes do not break a sweat. The 2.5GbE port keeps the network from bottlenecking. The DS224+ has Quick Sync too but only 1GbE.
DSM is genuinely more polished than QTS. If you have never used a NAS and want the lowest friction, the Synology DS224+ is the safer pick at $200 less. QTS has more features but a steeper learning curve.
Better alternative: Synology DS224+ 2-Bay NAS
QNAP's Container Station is a competent Docker frontend, and 8GB stock RAM accommodates three or four containers without immediate upgrade. The N5095 is fast enough for Immich's machine learning containers. The 2.5GbE port handles concurrent uploads from multiple devices.
QNAP's security history is concerning. The Deadbolt and Qlocker ransomware campaigns specifically targeted QTS units exposed to the internet. Either keep your QNAP behind a VPN/Tailscale or buy a Synology where DSM has had fewer incidents.
Better alternative: Synology DS923+ 4-Bay NAS
If you need more than 2 bays, QNAP's TS-464 (4-bay version of this same platform) or the Ugreen DXP4800 Plus and TerraMaster F2-424 (which is actually 2-bay despite the F2 name) deserve a look. The Ugreen has DDR5 and 10GbE, the TerraMaster has an 8-core i3 — both compete favorably with the TS-264's bigger sibling.
Better alternative: Ugreen NASync DXP4800 Plus 4-Bay NAS
If you intend to wipe QTS and run TrueNAS or Unraid, you are paying for hardware you will under-utilize. The Beelink ME mini gives you 6 NVMe slots and a clean N150 platform for $300 — better value if QTS is not part of the equation.
Better alternative: Beelink ME mini Mini PC (DIY NAS Server)
Ecosystem & Community
QNAP's software stack covers everything DSM does and more, with a steeper UX learning curve. r/qnap (30K) and r/homelab (700K+) cover TS-264 setup. The platform's largest weakness is its security incident history.
Compatible Software
What to Build First
Install two 256GB M.2 NVMe SSDs as cache, configure Plex Media Server in Container Station with /transcode mapped to a tmpfs RAM disk, and stream 4K HDR Plex to a household over the 2.5GbE port. The TS-264's Quick Sync handles transcodes the Synology DS923+ cannot.

Frequently Asked Questions
Is the QNAP TS-264 safe to use after the Deadbolt and Qlocker ransomware incidents?
Yes, with normal precautions. Both incidents targeted QNAP units with web UIs exposed directly to the internet via port forwarding or UPnP. Keep QTS updated, disable UPnP on your router, never port-forward the QTS web UI, and access remotely only via myQNAPcloud, Tailscale, or a VPN. Internal network use is not at elevated risk.
Can the TS-264 transcode multiple 4K Plex streams?
Yes. The Intel N5095's Quick Sync handles 4K HEVC, 10-bit, and HDR transcoding in hardware. Two simultaneous 4K-to-1080p transcodes run comfortably with CPU usage around 30-40%. The 2.5GbE port supports the bandwidth (a 4K HDR stream is ~50-80Mbps). The DS224+ has similar transcoding power but is bottlenecked by 1GbE.
Does the TS-264 support any M.2 NVMe SSD?
Yes. Unlike Synology, QNAP does not enforce a vendor whitelist for M.2 SSDs. Any standard M.2 2280 NVMe drive (Samsung 980/990, WD Black SN770, Crucial P3 Plus, Kingston KC3000) works for cache or storage. PCIe 3.0 x1 limits each slot to ~1GB/s, so high-end Gen 4 SSDs are wasted bandwidth here.
How does QTS compare to Synology DSM?
Feature-equivalent but different philosophies. DSM has a cleaner UI, better mobile apps, and easier discovery. QTS has more configurability, a larger app ecosystem (variable quality), and ZFS support via QuTS hero. Power users often prefer QTS; new users typically find DSM easier.
Is 8GB RAM enough for the TS-264?
For QTS plus 3-4 Docker containers, yes. For Immich with machine learning, Plex with multiple transcodes, plus Nextcloud and Jellyfin, expand to 16GB. RAM upgrades are unrestricted — any standard DDR4-2933 SO-DIMM works.
What is the difference between QTS and QuTS hero?
QuTS hero is QNAP's ZFS-based OS variant. It adds end-to-end checksums, inline deduplication, compression, and snapshots with copy-on-write semantics. QuTS hero requires more RAM (8GB minimum) but provides enterprise-grade data integrity. The TS-264 supports both — you choose during initial setup. Most home users stick with QTS for the broader app compatibility.
Should I get the TS-264 or the Synology DS923+?
Different products. The TS-264 is a 2-bay with Quick Sync, 2.5GbE, and HDMI for $500. The DS923+ is a 4-bay with ECC RAM, M.2 NVMe, and 10GbE PCIe slot for $600. Choose TS-264 for media transcoding and 2-bay convenience; choose DS923+ for 4-bay capacity, ECC, and the Synology software ecosystem.
