Help Creating a Pool for All SSD NAS

TrueNAS General
1

Hi! I’m new to NAS world and recently installed TrueNAS Scale on Ugreen NASync DXP480T Plus. It has the following configuration:

OS Version:TrueNAS-SCALE-24.04.2
Model:12th Gen Intel(R) Core™ i5-1235U
Memory:16 GB
Samsung 990 PRO SSD NVMe M.2 PLCe Gbe - 4 Drives
Boot SSD 512 GB (NVME M.2 GEN 3X4 2242 SSD)

I intend to use this NAS for storing photos, videos, documents and movies, plex server and sharing them whenever needed. How should I setup the pool among the 4 NVME SSD drives and with what configuration for encryption and Data VDevs. The following options are available : Stripe, Mirror, Raid Z1 to Z3, dRAID 1 TO3 etc)

Best

You need to do some research on what is possible first and then assess the level of risk vs capacity you are willing to live with. You cannot use Z3 for example as that requires 5 disks minimum and dRAID is not applicable for single server application. Read here and here.

I’m not sure that’s correct.

dRAID is not applicable, but its not applicable because it only makes sense when you have an immense number of disks… ie when you start talking about multiple disk shelves.

RaidZ is probably the way to go, so you should decide if you want extra redundancy or minimal redundancy.

If capacity is most important, you should use RaidZ1

This will use 1 disk for redundancy and provide 3x the space of a single disk for storage.

As the Samsung 990 PRO SSD NVMe are fairly fast and fairly reliable, it should be safe to use RaidZ1

If you wanted additional redundancy then you could use RaidZ2, whcih means two drives could fail before you would lose data.

I honestly wouldn’t bother with encryption.
