Hello together,
I plan to Build my first TrueNAS (SCALE) Storage Server for home usage (Plex media / SAMBA/NFS shares). Currently I have a Synology 4 Bay Diskstation, but this will be replaced by TrueNAS
What have I now for hardware?
I have a new 16 bay server case which have plenty enough of disks for future expansion:

I think cause of energy costs, I would only use max 8 disk slots, the amount of storage size is enough depends on the following disk size
What disks I plan to use?
I plan to buy the Toshiba Enterprise Disks (MG08 series), maybe the 14TB or 16TB version.
Which ZFS Pool Design should I use?
I read on many pages several discussions based on RAIDZ2 vs mirror etc. When you want to use RAIDZ2 with big disks the "best" disk amount should be a pool of 6 disks, whould you confirm this?
The problem with RAIDZ2 is the expansion, when I use 6 disks with 16TB each, then I must replace all 6 disks (example with 20TB disks), to get an increased pool.
Instead using an RAIDZ2 I considered maybe using Mirror VDEVs, for example we have 3 VDEVs, for future expansion I should only replace 2 disks within a single VDEV and you get a increased ZFS pool.
VDEV 1:) DISK_1 + DISK_2
VDEV 2:) DISK_3 + DISK_4
VDEV 3:) DISK_5 + DISK_6
The downside of Mirror VDEVs is the disk space ratio, in this example you have usable only 3 disks (3x16TB), with RAIDZ2 you have 4 usable disks (4x16TB)
I´m not sure which ZFS pool design I should choose :/
Core Hardware components
Independent of which ZFS pool design I choose, the Mainboard + CPU + RAM should not consume too much power, for me would be any small SoC CPU enough, but in 2022 maybe there are upcoming new CPUs with low power, any suggestions ? For RAM I would like to select 2x16GB RAM, and the mainboard would be grea to have enough SATA slots.
