QNAP HS-264-8G-US two-bay NAS review

The QNAP HS-264-8G-US is a two-bay network storage appliance dressed like a small set-top box. Its unusual selling point is not extra storage expansion, but a fanless chassis, dual HDMI 2.0 outputs and two built-in 2.5GbE ports. That makes it a model to examine when a living-room display and a wired file-sharing role belong in the same plan. This is a documentation-based assessment of QNAP's exact model and U.S. package references, not a hands-on test; the official product page describes the HS-264 as a multimedia NAS, while the exact U.S. store route returned a sold-out page when checked.

Two native SATA bays, with a drive-fit check still required

QNAP lists two 3.5-inch SATA bays, ships the base package without data drives, and names 3.5-inch SATA hard disks and 2.5-inch SATA SSDs in its detailed media table. The product overview also describes 3.5/2.5-inch SATA bays, but the narrower hardware compatibility list does not establish support for every 2.5-inch hard drive. Do not buy by the connector label alone: check the complete model code, capacity and current HS-264 entry in QNAP's drive compatibility tool. A mirror requires two individually compatible disks and uses both of the model's native positions; a two-bay number is not a capacity estimate.

At default settings, the HS-264 runs QTS and QNAP lists a two-drive RAID 1 option. A healthy mirror can keep the volume available after one member drive fails, but it does not recover a deleted file, undo ransomware, or replace a separate copy. QTS file services include SMB/CIFS and NFS, so local clients can access the NAS over a wired network even when the chassis is also connected to a television. The base package is diskless, so the buyer must budget for and install the drives rather than assume an out-of-box mirror.

A quiet design does not make the disks silent

QNAP calls the HS-264 fanless and describes its low-vibration, set-top design. That can be useful in a shared room where a conventional fan noise is unwelcome, but the installed disks remain mechanical devices: their seeks and vibration still matter, and a hot drive can raise the enclosure's temperature. QNAP recommends 5400-RPM or low-temperature/low-noise NAS drives to reduce heat and vibration. Its user guide also says not to obstruct ventilation. Check the cabinet dimensions, power-adapter position, cable clearance, tray access and airflow instead of treating “fanless” as permission to tuck it into a sealed space.

The product page describes HDMI 2.0 output up to 4K at 60 Hz and a home-theater workflow through QNAP's HybridDesk Station. Its processor also supports hardware-assisted H.264 video work according to QNAP, but playback quality depends on format, software, system load and available bandwidth. HDMI is a direct display connection; it does not replace the NAS's network services. QNAP lists an IR sensor and names RM-IR004 as an accessory, while the model guide's package list does not include a remote. If couch control matters, confirm whether the exact offer includes one instead of assuming it comes in the box.

Two 2.5GbE ports, not a guaranteed 5Gbps file copy

Each of the two built-in RJ45 interfaces is rated up to 2.5GbE. QNAP describes an aggregate figure of up to 5Gbps when port trunking is configured, but that does not change a single port's negotiated rate or prove that one client will transfer at 5Gbps. A compatible switch or router, client adapter, cabling, storage workload and selected network mode all matter. If a single workstation is the priority, evaluate the whole path and model-specific performance evidence, not the sum printed beside two ports.

The HS-264 is comparatively constrained as an upgrade platform: QNAP's detailed hardware specification says its 8 GB DDR4 memory is not expandable, and the model page lists no onboard M.2 positions or PCIe expansion slot. The two SATA trays therefore remain its native internal drive positions. The 8 GB configuration meets QNAP's published baseline for optional QuTS hero, but that OS's inline-deduplication threshold is 16 GB and QNAP recommends 32 GB for optimal performance. This fixed-memory model cannot reach those levels. QTS is the default; the optional QuTS hero/ZFS route is a separate operating-system choice, and QNAP says switching requires a backup and disk removal. Make that decision before populating it, not as a casual toggle after setup.

Who should shortlist it—and who should compare another NAS?

Consider the HS-264 if a two-bay file server, multigigabit wired ports, a fanless enclosure and direct HDMI output form one coherent home setup. It can host two supported drives in a documented QTS mirror, stream files to other clients, and connect directly to a display. Its main compromises are fixed 8 GB RAM, no listed internal M.2 or PCIe expansion, two bays total, no data drives in the base package, and a drive-media list that should be checked against the exact SKU. A RAID 1 mirror consumes both trays and is still not a second backup location.

Compare it closely with QNAP's TS-264-8G-US if storage flexibility matters more than fanless placement. The TS-264 is also a two-bay, dual-2.5GbE NAS, but its reviewed configuration lists separate M.2 positions and PCIe expansion; its own memory documentation conflict is a separate model-specific question. The HS-264's appeal is its set-top/fanless construction and fixed multimedia I/O, not a larger storage ceiling. Also compare the HS-264's exact 3.5-inch HDD / 2.5-inch SSD list with your planned drive, and check network hardware before paying for a faster link.

For this U.S. model, QNAP's product page and v4 user guide are the useful references for ports, installation and package contents; the live compatibility list is the next step for a specific drive. The direct U.S. store route showed a sold-out/404 response on the review date, so this assessment makes no claim about current retail stock, seller price or offer contents. Check the exact HS-264-8G-US suffix, drives, optional remote and any other bundle items on the seller's own page. The site's registered BuyerShortlists purchase details are an assessment path, not a compatibility certificate or guarantee of availability.
