Qnap launches NAS with x86 CPU in China: Zhaoxin-based models are available worldwide


Qnap quietly launched a six-bay TVS-675 NAS powered by an eight-core Chinese x86 CPU designed by Zhaoxin, a joint venture between Via Technologies and the Shanghai Municipal Government. The NAS for small businesses (SMB) is one of the first (if not the first) commercial devices to be marketed in the United States and Europe. The KX-U6580 processor was developed primarily for the Chinese market.

Zhaoxin was established in 2013 to build x86 processors for the Chinese local market, reducing reliance on AMD and Intel-designed processors, but retaining compatibility with the huge x86 software library.Zhaoxin’s previous generations of products were not successful due to extremely low performance, and the latest Kaixian KX-6000 series is not a performance champion in general tasks (according to our Review). But it seems that Qnap found that the eight-core 2.50 GHz open display KX-U6580 (equipped with Zhaoxin C-960 graphics card) is sufficient to meet the needs of its entry-level NAS.

Generally, Qnap’s entry-level network area storage devices use Arm-based SoCs or Intel Celeron SoCs supported by the company’s low-power architecture. NAS manages files, runs lightweight applications, or encodes videos, so these cheap SoCs are sufficient for their workloads. Zhaoxin’s Open Display KX-6000 can of course run light applications, but as revealed by our evaluation, its media encoding performance is very low by today’s standards, probably because it lacks tests that are suitable for us under Windows. Certain hardware encoders of the scene, and its general architecture is not entirely suitable for such tasks.Keep this in mind TVS-675 NAS from Qnap It is mainly aimed at small and medium-sized enterprises that hardly need it for media encoding. This shortcoming of KX-6000 may not affect users of the NAS. In addition, Qnap stated that SoC does support H.264/H.265 transcoding of its operating system.

Speaking of Qnap TVS-675, this NAS is expected to provide small and medium-sized enterprises with high capacity, high performance, scalability and fairly fast network connections. The NAS has six hot-swappable 3.5-inch bays for large-capacity SATA hard drives, two SO-DIMM slots for DDR4 memory modules (8GB is included with the system, but you can install up to 64GB), two Two M.2-2280 slots are used for SSD supporting PCIe 3.0 x1 or SATA interface, and two PCIe 3.0 x4 slots for SSD or network card. The device also has two 2.5 GbE ports, two USB 3.2 Gen 1 Type-A connectors, two USB 3.2 Gen 2 Type-A ports, and an HDMI 2.0 output.

Qnap equipped the TVS-675 with three fans to cool the PC-oriented SoC, six HDDs, two SSDs and expansion cards. The company claims that the fan produces 23 dB of noise (although it did not disclose how it measured this level).

Qnap TVS-675 can choose QTS or enterprise-level ZFS QuTS operating system. QTS supports all the features of entry-level NAS, including Qsync cross-platform file sharing (applicable to Apple, Windows, IBM AIX and Linux machines), Qtier caching technology that automatically moves frequently used files/data to SSD, snapshots, RAID mode, virtual JBOD , FTP server, HTTP access, etc. NAS also supports QNAP certified first-party and third-party applications.
