4 bay NAS 2 independent disk groups for RAID 0

Unread post by Geky » Wed May 16, 2018 7:58 pm

Am planning for my new NAS with 4 bays and 4x6 TB WD Red disks.
I want to setup 2 RAID 0 of 2 disks each.
Is it possible if I create 2 disk groups and then on each disk group create the RAID 0?

No disk groups needed for such a basic setup.

Thank you.
However I am not sure I fully understand.
Does creating a volume (RAID 0 in this specific case) spanning over 2 disks automatically create a disk group?
Or a disk group is not created at any time and the volume just spans over 2 disks.

My understanding from Synology knowledge base is that a disk group is the basic foundation upon which volumes are built.
So I would expect that either manually or automatically (taken care by DSM when building the volume) a disk group is required for anything that spans more than 1 disk.

Group will not be created and its not needed also if you don’t wanna use them. With small number of drives and volumes there is no need
