Start with the exact i5 configuration
The TVS-h874-i5-32G uses a six-core, twelve-thread Core i5-12400, 32 GB of DDR4 memory and eight SATA drive bays. QNAP's hardware specifications list a 64 GB memory maximum, two M.2 PCIe Gen4 x4 slots, and PCIe Gen4 x16 and x4 expansion slots.
The standard network arrangement is two 2.5GbE ports. A 10GbE result from an expanded review system should not be presented as the performance of the base network configuration. Related TVS-h874 variants also require their own specification check.
This exact-model discipline matters because the buying decision often combines storage, networking and application hosting. A processor capable of more work does not remove the limits imposed by disks, memory allocation or the network connection.
Practical transfers were strong on an expanded test system
One hands-on test added a dual-port 10GbE adapter to the i5 system. Its 25 GB file-copy results were approximately 9 Gbit/s for reads and 8.7 Gbit/s for writes. An encrypted copy reached about 8.3 Gbit/s in that particular setup.
The same test's folder containing roughly 10,500 files transferred at about 2.5 Gbit/s. That difference is relevant to office backups and document repositories: a NAS that handles a large file quickly may spend much more time processing a similar quantity of small files.
These results support a strong large-file use case with the tested network expansion. They do not establish the duration of an arbitrary backup job or prove that every storage layout will reach the same figures. The complete path includes the client, protocol, drive arrangement and protection settings.
A second test adds a different perspective
A separate evaluation used eight 22 TB WD Red Pro drives in RAID 6 with a QNAP 10GbE card. In its 4K random workload, SMB results were about 2,384 read IOPS and 2,035 write IOPS; iSCSI produced a different result on the same reviewed platform.
This is a useful counterweight to sequential throughput figures. Mechanical disks can offer substantial aggregate transfer speed while still limiting small random requests. Changing the access protocol also changes what the benchmark is measuring.
Cartennas would not combine those numbers with the other review into a single average score. They describe different configurations and workloads. Together, they show why a proposed virtual-machine or database role needs its own latency and concurrency test, even if large file copies look excellent.
Software choice changes the storage design
QNAP offers a choice between its QTS and QuTS hero environments on this platform. QuTS hero uses ZFS, so selecting it is a storage-architecture decision rather than simply choosing a different interface.
Memory must support the operating environment and any additional services. Features such as compression or deduplication should be evaluated against the actual data and resource budget, rather than enabled because the processor appears powerful enough.
The same restraint applies to hosting applications alongside storage. Consolidation can reduce the number of devices, but it also makes a NAS maintenance window relevant to more services. The recovery plan should account for those dependencies, including how applications return after the data is restored.
Expansion is valuable when it solves a measured constraint
The available PCIe and M.2 options give the TVS-h874 room to evolve. A faster network adapter can help when the existing link is saturated. SSD resources may be more relevant when the workload is constrained by random access. Those are different reasons to spend money.
Adding both without measuring the workload can leave the important constraint untouched. A faster link will not eliminate a slow client, and a cache is not a substitute for enough sustained storage performance when the active data does not remain in it.
Cartennas recommends the TVS-h874 for teams prepared to operate that flexibility deliberately. The i5 configuration is a credible starting point for demanding file services and selected additional workloads, provided the design reserves enough memory, uses the appropriate network expansion and retains an independent recovery path.
