TS-664-8G: specifications and dated store comparison →

A six-bay x86 NAS with dual 2.5GbE, NVMe and PCIe expansion for flexible home-lab or small-office growth.

Exact US MPN TS-664-8G-US; official hardware table TS-664-8G; 8 GB SODIMM DDR4 Since 2024/01; 6 x 3.5-inch SATA 6Gb/s The system is shipped without HDD. For the HDD compatibility list, please visit https://www.qnap.com/compatibility/.

Based on the current QNAP specification tables. We have not tested this NAS ourselves. The hardware-page software tables are QTS 5.2.9 / QuTS hero h5.2.9 (version-bound). TS-664 is listed in Applicable Models on the separate QuTS hero h6.0.2.3591 notes dated 2026-08-24; that listing is not the h5.2.9 feature table. See evidence and test gaps ↓

QNAP TS-664-8G network attached storage system

Is the TS-664-8G right for you?

Six-bay backup and media storage

A six-bay x86 NAS with dual 2.5GbE, NVMe and PCIe expansion for flexible home-lab or small-office growth.[1]

Good fit

Light containers with room to expand networking

Plan the array and client path around 10GbE: Optional via PCIe expansion card; 2.5GbE: 2 (2.5G/1G/100M/10M).[1]

Good with planning

You need built-in 10GbE

The exact factory configuration and platform limits do not make this the safest default for that need: you need built-in 10gbe.[1]

Hardware, storage and network planning

01

The exact factory configuration matters

This page covers TS-664-8G-US, mapped to the official TS-664-8G hardware table. CPU: Intel® Celeron® N5095 4-core/4-thread processor, burst up to 2.9 GHz. Factory memory: 8 GB SODIMM DDR4 Since 2024/01.[1]

02

Plan storage and networking together

Storage: 6 x 3.5-inch SATA 6Gb/s The system is shipped without HDD. For the HDD compatibility list, please visit https://www.qnap.com/compatibility/. Connectivity: 10GbE: Optional via PCIe expansion card; 2.5GbE: 2 (2.5G/1G/100M/10M). Advertised port speed is not a guarantee for one file transfer; drive count, RAID, protocol, client and switch can each become the limit.[1]

03

Read measured results with their setup

No original 8GB (since 2024/01 SODIMM) throughput test was opened. Hardware-Inside tested 4GB SODIMM, RAID-0 thick 800GB, ordinary HDDs without SSD cache, drive model and count unknown, one 2.5GbE client. ATTO 4.01.0f1 Direct I/O 256MB QD4 maxima Read 230.63 / Write 279.48 MB/s (prose 230/279; do not reverse). CDM 8.0.4 3 runs 1GiB: SEQ1M Q8T1 240.68/292.09; SEQ128K Q32T1 239.60/290.29; RND4K Q32T16 231.96/72.23; RND4K Q1T1 19.91/13.53. Plex was a Full-HD browser client; codec/bitrate/hardware-transcode path unstated — not a 4K claim. 23.22/44.02 W are QNAP manufacturer figures, not this lab’s meter.[4][1]

What still needs a real-world test

We have verified the specifications, but have not found an original test that we can reliably apply to this exact model. The advice above follows the documented features; performance, noise and long-term reliability are not independently established here.

Before you buy

US listings and ownership costs

Budget the complete storage system

Include compatible drives, an independent backup destination, network upgrades, cables and any UPS or expansion cards required by the workload.[1]

Treat listings as dated evidence

Amazon/Newegg numeric rows keep their original 2026-09-10T01:06:35+00:00 observation times. The QNAP Store row is the historical 2026-09-10 identity-qualified listing with unknown price and stock; a later cookies-disabled Magento extract was not used as a live US offer. Recheck the live page before buying.[2][3]

Questions before buying

Which TS-664-8G configuration does this page cover?

It covers the exact US MPN TS-664-8G-US. The selected official hardware-table heading is TS-664-8G.[1][2][3]

Are drives included?

The official hardware table describes the platform. Store bundles can change, so confirm the exact seller listing and included drives or accessories before ordering.[1][2][3]

What network connection should I plan for?

The selected official configuration lists 10GbE: Optional via PCIe expansion card; 2.5GbE: 2 (2.5G/1G/100M/10M). A client, switch, cabling, protocol and storage array must all support the intended speed.[1]

Has ChooseCompute tested this NAS?

No. Hardware-Inside’s ATTO/CDM numbers are a 4GB RAID-0 sample, not the current 8GB SODIMM revision.[4][1]

Is the listed price current?

Amazon/Newegg numeric rows keep their original 2026-09-10T01:06:35+00:00 observation times. The QNAP Store row is the historical 2026-09-10 identity-qualified listing with unknown price and stock; a later cookies-disabled Magento extract was not used as a live US offer. Recheck the live page before buying.[2][3]
