Advice for new setup

[chrispazz]

Hello,
I currently have a Synology NAS 218+ with 2 TB disk in raid (2x2TB). I run a couple of VM and about 10 dockers.

I just got an HP Pro Desk 600 G1 with 16GB RAM (no ECC), Intel I5-4590, 1 SSD (512GB) consumer grade (WD-Green), and two more HDD (2x1TB).
Which is the best setup to gain best from this hardware?

I would like to run dockers in a Debian VM, add come Containers and some VM (Windows 10 client, Firewall VM, etc).
Should I use ZFS and the 2 extra drives in raid inside the ProDesk?
Should I use 218+ as Raid and keep extra drives not in raid?
Thank you
Chris

I made a first try creating a zfs pool from the two HDD and installing Proxmox on it.
I then added SSD as storage for VM and Containers.
All Is running quite good but I have about 5/10% IO delay without intensive usage and this output from pveperf:

CPU BOGOMIPS:      26340.88
REGEX/SECOND:      3548531
HD SIZE:           895.45 GB (rpool/ROOT/pve-1)
FSYNCS/SECOND:     26.49
DNS EXT:           43.56 ms
DNS INT:           23.06 ms

and the disk performances seems very low....

Any idea?
