QNAP HS-264 2-DRIVE Fanless NAS Intel 4C/4T - HS-264-8G-US

QNAP HS-264-8G-US Fanless 2-Bay NAS with Intel Celeron and Dual 2.5GbE

The QNAP HS-264-8G-US is a silent, fanless 2-bay NAS built around Intel's Celeron N5105 quad-core processor — the right device when you need a compact, always-on network storage node in an environment where fan noise is unacceptable: home offices, small meeting rooms, quiet workspaces, or AV equipment closets. With 8GB DDR4 RAM, dual 2.5GbE ports, and SATA 6Gb/s drive support, it punches well above the bandwidth ceiling that held back single-gigabit NAS boxes for years.

Overview

Fanless NAS designs make an engineering tradeoff: no moving cooling parts means zero acoustic output, but thermal headroom becomes the hard constraint. QNAP addresses this by pairing the N5105's 10W TDP with a passive heatsink chassis — the result is a device that runs continuously without a sound signature. For a network attached storage deployment in a sound-sensitive space, this is the spec that makes or breaks the placement decision. The HS-264-8G-US fits 3.5-inch SATA drives in both bays, so you can load standard high-capacity surveillance or desktop drives without hunting for exotic form factors.

Key Features

• Intel Celeron N5105, 4-core / 4-thread at 2.0 GHz (burst 2.9 GHz): The N5105's four cores handle simultaneous transcoding, file indexing, and network I/O without contention — a meaningful step up from older dual-core NAS CPUs that stall when Plex or QNAP's multimedia apps request on-the-fly transcoding while a backup job runs in the background.
• 8GB DDR4 RAM (non-expandable): 8GB is sufficient for most two-bay workloads including virtualization light containers, but the non-expandable ceiling is a real constraint — if you anticipate running multiple simultaneous VMs or RAM-hungry QNAP apps, factor this in before committing. There is no upgrade path.
• Dual 2.5GbE ports (2.5G/1G/100M): Two 2.5GbE interfaces enable link aggregation / port trunking, which pushes aggregate throughput to the 589 MB/s ceiling the HS-264 is rated for. That's roughly 5x the bandwidth of a single-gigabit NAS — enough to saturate two simultaneous 4K video streams or feed a small design team's shared storage. Connect both ports to a managed 2.5GbE switch that supports LACP for full benefit.
• 2 x 3.5-inch SATA 6Gb/s bays: SATA 6Gb/s is the standard interface for spinning NAS drives (WD Red, Seagate IronWolf, and equivalents). Both bays accept 3.5-inch form factors, so you're not restricted to 2.5-inch laptop drives. SATA 3Gb/s backward-compatibility means older drives work, though they cap at that interface speed.
• 4GB Flash (dual-boot OS protection): QTS firmware runs from onboard flash, keeping OS storage entirely separate from your data drives. The dual-boot protection means a failed or corrupted firmware update doesn't brick the device — the NAS can roll back to the previous working firmware automatically.
• Fanless passive cooling: No fan means no fan failure, no periodic bearing replacement, and no noise floor contribution. The tradeoff is a stricter ambient temperature ceiling and reduced tolerance for sustained heavy CPU loads compared to an actively cooled unit. Position the HS-264-8G-US in a ventilated enclosure or open shelf — do not mount it in a sealed rack panel without airflow.

Integration and Compatibility

The HS-264-8G-US runs QNAP's QTS operating system, which supports a broad application ecosystem: Plex Media Server, QNAP Surveillance Station for IP camera recording, HBS 3 for hybrid cloud backup, and Container Station for Docker-based workloads. The dual 2.5GbE interfaces integrate with standard 802.3ad LACP-capable switches. For deployments mixing this NAS with other QNAP storage and networking products, the QTS management interface provides unified device visibility. SMB/CIFS, NFS, AFP, FTP, iSCSI, and WebDAV protocols are all supported through QTS, making cross-platform file access straightforward in mixed Windows/macOS/Linux environments. QNAP's myQNAPcloud service provides remote access without requiring a static IP or manual port forwarding configuration.

Frequently Asked Questions

Q: Can the RAM in the HS-264-8G-US be upgraded beyond 8GB?

A: No. The HS-264-8G-US ships with 8GB DDR4 and the memory is not user-expandable. Plan your workload requirements accordingly before purchasing.

Q: Does the HS-264-8G-US support 2.5-inch drives in its bays?

A: The bays are designed for 3.5-inch SATA drives. 2.5-inch drives may require an adapter bracket to seat properly — check QNAP's compatibility list before installing smaller-format drives.

Q: What is the maximum transfer speed of the HS-264-8G-US?

A: With both 2.5GbE ports configured for port trunking, the HS-264 is rated for up to 589 MB/s — effectively matching single-port 10GbE NAS throughput for multi-client workloads.

Q: Is the HS-264-8G-US suitable for 24/7 always-on operation?

A: The fanless design is built for continuous operation, but passive cooling means ambient temperature and airflow around the chassis directly affect thermal headroom. Install it in a well-ventilated location, not in a sealed enclosure.

Q: What operating system does the HS-264-8G-US run?

A: It runs QNAP QTS, loaded from 4GB onboard flash with dual-boot OS protection. Data drives are separate from the OS flash, so drive failures do not affect the firmware.

Q: Does the HS-264-8G-US support IP camera recording?

A: Yes. QNAP Surveillance Station runs on QTS and supports IP camera recording and playback. Camera channel capacity depends on the Surveillance Station license installed — verify channel count requirements before deploying as a dedicated NVR replacement.

Jerry Tildsen

The spec I keep coming back to on the HS-264-8G-US is the combination of dual 2.5GbE with the fanless chassis. Most silent NAS units are throughput-limited — single gigabit, maybe 110 MB/s real-world. This one runs port trunking to 589 MB/s without making a sound. That gap matters the moment you put a real workload on it.

Technical Highlights:

• Intel Celeron N5105 (burst 2.9 GHz): Four cores with a 2.9 GHz burst ceiling give this unit enough headroom for on-the-fly transcoding tasks that would stall a dual-core NAS — practical if you're running QNAP Multimedia Console or Plex alongside a backup job.
• 589 MB/s with link aggregation: Both 2.5GbE ports bonded via LACP on a compatible switch deliver throughput that competes with single-port 10GbE NAS hardware at a significantly lower network infrastructure cost.
• 4GB dual-boot flash (OS protection): Firmware lives on dedicated flash separate from data drives. If a QTS update goes wrong, the device rolls back rather than failing to boot — this is the kind of silent reliability feature that matters in an always-on deployment where you're not physically present to recover it.

Deployment Considerations:

• Passive cooling demands real airflow around the chassis. Don't rack this in a sealed 1U or 2U panel without confirmed airflow — thermal throttling will pull CPU performance down under sustained load and shorten drive life.
• The 8GB RAM ceiling is non-expandable. If you plan to run Container Station with multiple Docker workloads alongside Surveillance Station, audit your expected RAM consumption before deploying — there is no upgrade path once the unit is in service.

The HS-264-8G-US (often searched as HS 264 8G US) fits best in a quiet home office or small business environment where acoustic neutrality is a hard requirement and the workload stays within a two-drive, dual-stream ceiling — a media producer's local backup node or a small-office shared drive are the deployment scenarios it was clearly built for.
