QNAP TS-464 vs Asustor Nimbustor 2 Gen2 AS5402T

The QNAP TS-464 is the better pick for most people who want a four-bay NAS with room to grow and stronger multi-drive RAID options. The Asustor AS5402T is the better pick for a fast two-bay setup: dual 2.5GbE, four NVMe M.2 slots and HDMI 4K output beat the QNAP on connectivity and media playback. Build quality is comparable at this tier, and owners of both brands praise the hardware while noting the QNAP QTS interface takes more learning than Asustor's ADM.

  • Choose the QNAP TS-464 if you want four drive bays, RAID 5 or RAID 6 protection, and 8 GB of RAM out of the box for storage-first use.
  • Choose the Asustor AS5402T if you want dual 2.5GbE networking, four NVMe cache slots and HDMI 4K transcoding in a compact two-bay unit.

What reviewers say

QNAP TS-464

Owners treat the TS-464 as a capable, flexible 4-bay NAS for the money. The common complaint is that QTS takes more getting used to than Synology's DSM.

What people mention
  • SoftwareCriticisedOwners say QTS has a steeper learning curve than Synology DSM.
  • RAID optionsPraisedBuyers value RAID 5 and RAID 6 support across four bays.
  • Drive baysPraisedHot-swappable bays make replacing or upgrading drives easy.
  • MemoryMixed8 GB installed helps app use, but heavy virtualization users may want more.

Asustor Nimbustor 2 Gen2 AS5402T

Owners and reviewers treat the AS5402T as one of the faster two-bay NAS units in its class, mainly for its 2.5GbE networking and four M.2 slots. Praise centers on build quality, quiet running and smooth 4K transcoding, while complaints focus on the diskless package and the smaller app library.

What people mention
  • Network speedPraisedOwners report large file transfers finishing much faster over 2.5GbE than on gigabit-only NAS units.
  • M.2 slotsPraisedReviewers like having four NVMe slots for cache or SSD volumes without sacrificing the hard drive bays.
  • NoisePraisedUsers describe it as quiet in normal operation, helped by the vented M.2 thermal design.
  • App ecosystemCriticisedSome owners say ADM has fewer third-party apps than Synology's DSM.

Questions and answers

Which is better for a Plex media server?
The Asustor AS5402T is the better fit. Its HDMI 2.0b output with 10-bit 4K hardware decoding lets it play directly to a TV, and dual 2.5GbE helps with multiple streams. The QNAP TS-464 has more bays for a large library but no HDMI.
Which holds more storage?
The QNAP TS-464, with four bays versus two. Four drives also let you run RAID 5 or RAID 6, which the Asustor cannot do with only two bays.
Is the Asustor faster on the network?
Yes, on paper. Dual 2.5GbE ports with SMB Multichannel can exceed Gigabit speeds when your switch and clients support it. The QNAP TS-464 is limited to Gigabit Ethernet.
Which is easier to set up?
The Asustor ADM system is generally friendlier for beginners. QNAP's QTS is more capable but has a steeper learning curve, a point owners of both brands commonly raise.
Is the QNAP worth stepping up to over the Asustor?
Step up to the QNAP if you need four bays, RAID 5 or 6, or 8 GB RAM for virtualization and containers. Stay with the Asustor if fast networking, NVMe slots and HDMI playback matter more than bay count.
Which lasts longer?
Both are built for continuous operation and neither has a clear durability edge. Longevity depends more on drive quality, cooling and RAID setup than on the enclosure brand.
