Our take on the QNAP TS-664-8G-US 6 Bay High-Performance Desktop NAS

The TS-664 is a six-bay desktop NAS built around an Intel Celeron N5095 quad-core CPU with 8 GB of RAM and two 2.5GbE ports. It stands out for its six drive bays in a compact desktop chassis, HDMI output, and a PCIe slot for adding a 10GbE card or NVMe cache drives. It suits home labs, small offices and media hoarders who want room to grow, and it competes with six-bay units from Synology and TerraMaster that often cost more or offer fewer expansion options. Reviewers praise the hardware for the money but note the Celeron limits heavy virtualization and that the 8 GB model is the one to get for containers.

Owners generally rate the TS-664 as strong hardware for the money, with praise for the six bays, dual 2.5GbE and PCIe flexibility. Criticism centers on the Celeron's limits for VMs and on fan noise under load.

What people mention
  • PerformanceMixedOwners say the quad-core Celeron handles file sharing and media well but bogs down with several VMs.
  • ExpansionPraisedThe PCIe slot and dual 2.5GbE ports are cited as the main reasons to pick it over rivals.
  • NoiseCriticisedReviewers note the fan becomes audible when drives are working hard.
  • SoftwareMixedQTS is feature-rich but users describe a steeper learning curve than Synology DSM.
  • MemoryCriticisedThe 8 GB installed RAM is seen as tight once containers and caching are enabled.

Questions and answers

Is the TS-664 good for Plex?
Yes. The Intel Celeron N5095 supports hardware transcoding, and the HDMI port allows direct playback. It handles 1080p and light 4K transcoding well.
Can I add a 10GbE card?
Yes. The PCIe slot accepts a compatible network card, and the two 2.5GbE ports can be aggregated. This is one of its main advantages over rivals.
How much RAM can it take?
It ships with 8 GB and supports up to 16 GB via two SO-DIMM slots. Upgrading helps if you run containers or virtual machines.
Does it come with drives?
No. The TS-664 is sold as a diskless enclosure, so you supply your own 3.5-inch or 2.5-inch SATA drives.
Is it better than a Synology six-bay?
It offers more hardware per dollar, including 2.5GbE and PCIe expansion. Synology counters with a more polished software ecosystem.
What RAID levels does it support?
It supports RAID 0, 1, 5, 6, 10 and JBOD. RAID 5 or 6 is typical for six drives with redundancy.
