QNAP TVS-h874X-i9-64G-US review

The TVS-h874X-i9-64G-US is the high-memory, built-in-10GbE member of QNAP's TVS-h874 selector family. The “X” and full i9-64G suffix matter: QNAP's U.S. selector labels this profile “By Request” and lists a 16-core/24-thread Core i9, 64 GB of DDR4 memory and two 10GBASE-T ports. The exact U.S. Store page displays the -US SKU, but neither a model page nor a search result settles present stock or the contents of a future seller offer. This is a source-based assessment, not an independent benchmark or use report.

Why the X configuration is not just an i7 upgrade

All three TVS-h874 selector profiles have eight native 3.5-inch SATA positions and two separate M.2 2280 PCIe Gen 4 x4 NVMe sockets. The i5 and i7 packages start with 32 GB and two built-in 2.5GbE ports; their faster networking is described as an optional PCIe card. The TVS-h874X-i9-64G starts with 64 GB, reaches the same 64 GB listed maximum, and includes two built-in 10GBASE-T ports alongside two 2.5GbE ports. QNAP describes the 10GbE NIC as preinstalled in a PCIe position. That is a meaningful purchase difference for a network path which needs a 10-Gbps built-in port, while the number of native SATA bays stays eight.

The hardware selector specifies an Intel Core i9 with 16 cores (8 performance and 8 efficiency) and 24 threads. QNAP's older series guide also identifies the X profile separately and lists a higher burst-frequency row, but the current selector does not give a processor part number. This is enough to distinguish the published profile; it is not a promise that a particular virtualization or video workload will perform at a given rate. No lab results or independent throughput testing are claimed here.

Eight SATA positions, two additional NVMe sockets

QNAP's current selector lists 3.5-inch SATA hard drives and 2.5-inch SATA solid-state drives in the eight front positions. It describes the two M.2 sockets separately and says M.2 SSDs are not hot-swappable. The English-U.S. guide also names 2.5-inch SATA hard drives among bay media, so confirm the exact drive and firmware on the manufacturer's compatibility list before treating that format as a supported purchase. Do not count the M.2 connectors as extra hot-swap bays or add an optional expansion enclosure to the chassis's native count.

Both QTS (EXT4) and QuTS hero (ZFS) appear as alternative software choices in QNAP's selector. Its eight-bay software tables include RAID 1 under each. An owner still has to choose a system, select two compatible drives and create the mirror; the standard guide's package list does not include data drives or a ready-made array. QNAP warns that changing between the two operating systems resets the NAS and deletes data. A mirror may help keep data available after one member failure, but it cannot replace an independent backup or recovery plan.

10GbE still needs a complete network

Either built-in 10GBASE-T jack meets a 10-Gbps minimum for one individual port. That does not make two jacks into one 20-Gbps client connection, and it does not mean a file copy will reach 10Gbps. The switch or router, peer NIC, cabling, storage arrangement and workload all remain part of the path. The 2.5GbE ports are separate interfaces with their own use cases. A 10.5-Gbps requirement for a single built-in port would be above the documented 10GbE ceiling, so do not read the second port or optional PCIe products as a 10.5-Gbps base interface.

There are two PCIe positions, with a 10GbE card preinstalled in one according to QNAP's selector. The other slot and available width must be checked against any optional storage or network card. QNAP lists two Type-A and one Type-C USB 3.2 Gen 2 ports, an HDMI 1.4b output and two M.2 sockets, but this is a desktop tower, not a rackmount chassis. Expansion choices should be confirmed together rather than treated as independent upgrades with unlimited clearance.

Check the footprint and the “By Request” identity

QNAP lists one 350W supply and a three-year standard warranty for this profile; the wattage is not a measured power-consumption result or redundant power. The selector gives HWD dimensions of 7.09 × 12.96 × 11.01 inches and says the feet are excluded, with as much as 1.18 inches of added foot-pad height depending on model. The English-U.S. guide groups the h874 X profile in a different dimensions table, so the listed chassis height does not agree cleanly across those documents. For a close shelf fit, verify the exact hardware revision and leave room for airflow and service. The “By Request” label is also a reason to confirm the exact TVS-h874X-i9-64G-US ordering identity, warranty and written contents before payment; a similar non-X SKU has different built-in networking.

The selector's net-weight figure is 16.18 lb; the English-U.S. guide's shared h874 row prints 7.06 kg (20.79 lb), whose paired units do not agree. If the shelf has a tight load limit, obtain a revision-specific weight from QNAP instead of treating either source figure as definitive.

Verdict

The TVS-h874X-i9-64G-US is the distinct fit when eight native SATA positions, two M.2 sockets, 64 GB of starting memory and a 10GbE built-in port are each relevant. Its principal advantage over the non-X i5 and i7 profiles is not a higher bay count but the preinstalled dual-10GbE path and the i9/64G specification. It retains the same key ownership tasks: validate exact disks and firmware, choose one OS, configure storage yourself, build a separate backup, and check the network end to end. The Store identity and “By Request” selector do not prove current availability or retailer additions, and no actual performance result is inferred.
