QNAP TVS-951X 9-Bay NAS for SMB Edge and Content Creators


So far we have looked at many NAS units in the lab, ranging from 2-8 bay units. Today we have our first 9-bay NAS from QNAP, the TVS-951X. The QNAP TVS-951X is really a 5-Bay NAS used for HDD storage, then includes an additional 4-Bays used for fast storage, or SSD’s. This configuration opens up many different possibilities for storage options. One can setup QNAP Qtier or go for fast SSD Cache Acceleration; each has its own unique advantages. The last option for these bays might be a fast SSD volume used for virtual machine storage.

Considered to be a budget-friendly NAS for SMB’s and a powerful tool for creators, the QNAP TVS-951X has features that are not found on lower-end units. Along with the extra for bays for SSD’s the TVS-951X includes built-in 10GbE connectivity to boost network performance.

Powering the QNAP TVS-951X processor is a 7th generation Intel Celeron Kaby Lake 3865U dual-core running at 1.8GHz. Memory on our NAS is 8GB of DDR4; this can be upgraded to 32GB. Compared to those lower-end NAS units running embedded CPUs and with 2GB of memory, this expands the roles that the unit can play on the edge. In our review, we are going to take a look at the QNAP TVS-951X and see how well it performs relative to other units we have tested.

QNAP TVS-951X 9-Bay NAS Overview

Taking a look at the front of the QNAP TVS-951X, we find the five 3.5” bays located at the top of the NAS, while the four 2.5” bays at the bottom. Along the left side, we see a power button and a USB One Touch Copy button and port at the lower left. A row of status LED’s display system activity and status indicators.

Installing SSD’s is also tool-free, drives slide in and snap down to lock in place.

Next, we are going to look at setting up the QNAP TVS-951X before we move to our performance testing.


  1. Any information on drive temps?

    You state you were surprised the 120mm fan was able to cool the machine in testing but I didn’t see any drive temperature readings for the various workflows.

    In extended / heavier use cases I wonder if the cooling will be adequate.

  2. What good is this article without a price tag? Haha – I literally don’t know what I should be comparing it to from the likes of Synology or whatnot without it. 🙂

  3. TVS-951X w/ (5) WD 8TB Red & (4) 500GB MX500
    Temps (C):
    CPU 46
    SYS 34
    SSD1/2/3/4 41 41 36 38
    HDD1-5 40 39 38 38 39
    FAN 646 rpm

    It’s on sale fairly often for under $600.

  4. If I were to put 9 x 1TB SSD into the drive bays, could I get one RAID 6 storage pool including all of them, or do the 4 x 2.5 slots remain independent?
