QNAP TS-364-8G three-bay NAS review

This assessment follows the QNAP TS-364-8G configuration identified in QNAP's U.S. hardware table. QNAP's expected U.S. Store URL for a model suffix ending in “-US” returned a not-found page when checked, so I do not claim that exact retail suffix or a current seller package. The manufacturer configuration is clear: three native SATA bays, one 2.5GbE network port, two separate M.2 positions and 8 GB memory with an 8 GB listed maximum. This is a research-based comparison, not hands-on use or an independent performance test.

Three native drive bays are the important distinction

TS-364 is a compact desktop tower designed around three SATA drive positions. That makes its main storage choice meaningfully different from a two-bay box: QNAP lists both a two-drive RAID 1 arrangement and a three-drive RAID 5 option. Those are different layouts, not interchangeable labels. A two-drive mirror uses two separately selected SATA drives and leaves the third native position outside that two-member mirror. RAID 5 uses three drives and gives a different balance of usable capacity and fault tolerance. Neither layout turns the enclosure into a backup destination by itself.

The physical bay question is easy to misread because QNAP also lists two M.2 2280 NVMe positions. They can support SSD storage or cache, but they do not add SATA trays and QNAP does not list them as hot-swappable. If the plan uses 2.5-inch SATA SSDs in the main trays, QNAP's manual says the 3.5-inch caddies need separate 2.5-inch tray bases. Data drives, M.2 SSDs and those tray bases are not something to assume from the chassis photo; the manual's listed package contents do not include data drives. Check each drive's full model code and capacity in QNAP's live TS-364 compatibility lookup before ordering.

One 2.5GbE port, not a pair

The TS-364 has one built-in 2.5GbE RJ45 connection. It can be a sensible middle ground if the NAS, switch or router, cable and client all support multigigabit Ethernet. It is not a 5GbE aggregate, and the port rating is not a promise that a file copy will run at 2.5Gb/s. Drive layout, client hardware, protocol overhead, concurrent work and the slowest link still matter.

QNAP publishes transfer results from its own lab using a named QTS version, a three-drive SSD RAID 5 set and a specified Windows client. Those are manufacturer test results in that environment, not independent evidence of what a buyer should expect. The more useful buying question is whether the rest of your path can use a single 2.5GbE link and whether the workload benefits enough to justify a multigigabit switch or client upgrade.

The 8 GB configuration has a firm memory ceiling

QNAP lists the TS-364-8G with 8 GB memory and an 8 GB maximum. That is a real distinction from the earlier TS-364-4G, which the same U.S. hardware page marks “Legacy” and lists with two SODIMM positions and a 16 GB maximum. The current 8G version starts higher, but do not buy it assuming that you can add memory later for a heavier application mix.

QTS is the documented default operating system. QNAP also describes QuTS hero as an alternative from QTS 5.2.1, with a published minimum of 8 GB RAM. The 8G model reaches that minimum, but not QNAP's 16 GB threshold for inline data deduplication or the 32 GB recommendation for optimal performance. A buyer who expects to run several virtual machines or other memory-hungry apps should check each app's requirements and the exact product revision instead of treating “NAS” as a workload guarantee. Switching operating systems is a separate migration that calls for a current backup and careful drive handling.

Where it fits—and what it does not solve

The TS-364-8G is worth comparing when a three-bay internal layout, one built-in 2.5GbE port and a QTS drive-layout choice all matter. A two-bay QNAP such as the TS-264 is physically smaller in drive count and has a different M.2 and memory configuration; a four-bay TS-464 adds another SATA position and has two 2.5GbE ports, with its own model-specific memory-source caveat. Those alternatives may be more appropriate if you have a strict minimum or expansion plan. The TS-364 is not automatically “between” them in value; exact drive needs and software workload decide.

QNAP lists an HDMI output and USB ports for display and peripheral functions, but a home-theater feature list should not replace checking the exact software package, supported codecs and client playback path. Nor does the product page's QNAP lab benchmark establish independent results. If quiet placement matters, the listed fan means this is not a fanless design, and installed drives can add their own noise and heat. Leave ventilation room and follow the setup guide.

Practical checks before choosing a seller

Confirm that the listing says TS-364-8G rather than TS-364-4G or another similarly named QNAP unit. Check whether the exact seller package is diskless or has a separately identified drive bundle; verify drive model and capacity in QNAP's compatibility list; and budget separately for any 2.5-inch tray bases or M.2 SSDs. For a mirror, identify two drives and an independent backup location before initialization. For RAID 5, understand the three-drive layout and recovery steps. Finally, trace NAS → switch/router → client and confirm the whole path, not just the NAS jack. No price, stock claim or seller package is assumed in this assessment.
