My QNAP NAS is TS-431P. Usually at https://192.168.8.167.
- A storage pool combines many physical disks into one large pool of storage space and may contain one or more RAID groups.
- However, with different sized HDDs, there will be wasted space as the minimum is the dominant.
- Multiple volumes can be created in a storage pool, enabling you to divide the storage space among different users and applications.
- Disks of different sizes and types can be mixed into one large storage space.
- Volume
- Thick is recommended for most cases.
Raid levels. I have multiple HDD with different sizes, and need to add more hdds if needed.
- RAID 0 (striping) but losing any disk means losing all the data. Not really a RAID.
- RAID 1 (mirroring). All hdds should be identical.
- RAID 5 (parity striping) but requires at least 3 similar drives.

Samba
Samba server works almost out of the box. Use
smbclient -L 192.168.8.192 -U admin
to see the folders and
smbclient //192.168.8.192/Public -U admin
to actually connect the server. The get command allows to download files to local computer.
Samba works on Thunar (or Nautilus) after installing gvfs, gvfs-smb and sshfs packages, see https://wiki.archlinux.org/title/Thunar#Using_Thunar_to_browse_remote_locations. Use smb://192.168.8.192 only.
