Replacement for old QNAP NAS

Recommended Posts

Hi Dear Community,


I looking around to replace my old QNPA NAS ARM (512MB RAM, 1.2 GHz) and Lenovo notebook (16GB RAM, i5-5200U, with proxomx on top of it), with something quicker.

My current setup is:

  • QNAP as a main storage device for entire home (4x1 TB RAID 5).
  • Lenovo notebook act as proxmox unit where I have Home Assistant VM, Ubuntu server VM and Ubuntu Desktop VM, with few non demanding containers for running some small python scripts.


I would like to replace two of these with something:

  • which would be capable of running all of these thing above (VMs, docker containers and Storage)
  • will be able to connect 4+ HDDs and make an RAID 5 where I can build this RAID using different disks size (unRaid probably?)
  • will be able to connect SSD for OS
  • RAM: 16GB+
  • CPU: 4 cores+?
  • HDD: Starts with min 4, max 6 drives, replace these with higher capacity in future, not in plan to add more drives
  • Transcoding not necessary, since I am playing movies mostly on Android TV which is handling 4k videos quite good. But you can convince me why I should invest in transcoding GPU :)
  • it will be quiet since it will be sitting in flat in one of the closet,
  • and it would be perfect to consume below 50 Watts at IDLE since the new thing will works 24/7, but maybe <50W is not possible and I have to accept higher consumption?


Would you be able to recommend something to build or buy? Appreciate all answers and tips

Preferences are to build this Home server and budget is below 1000 USD.

Used parts are totally OK for me.

I have 5x1 TB and 1x2 TB usded HDDs

Unraid IS NOT RAID but it has parity for redundancy and allows different sized disks. 


The OS is installed from the archives on flash into RAM at each boot and runs completely in RAM.


You can create pools of one or more SSDs for faster storage than the parity array. 


Unraid can host VMs, but many applications are available as dockers so you may not need VMs for that.

I understand the parity concept, but thanks for the resources.


Are you able to recommend some hardware which will consume as a little power as possible and at the same time will be able to run the VMs and docker setup as I have for today?
