Hi, I have 8x14TB drives, they get about 210MB/s R/W. What setup should I be going with if I am looking for maximum speed?
I will be running TrueNas, thanks in advance.

For maximum speed use mirror vdevs. Pool IOPS scale by the number of vdevs, so 4 mirrored vdevs will give you 4 times the IOPS of a single RAIDZ1/2 vdev.Hi, I have 8x14TB drives, they get about 210MB/s R/W. What setup should I be going with if I am looking for maximum speed?

Only if you have have sufficient IOPS consumers - i.e. with a single thread scaling will (basically) not occur.Pool IOPS scale by the number of vdevs, so 4 mirrored vdevs will give you 4 times the IOPS of a single RAIDZ1/2 vdev.
This machine is being used for backing up mainly (Mostly large files, and some small), might throw a VM or two on there. Only a single user.Only if you have have sufficient IOPS consumers - i.e. with a single thread scaling will (basically) not occur.
@ OP - whats your use case? VMs, large file storage, small file storage ... few user/processes/vms or many?
What are a SLOG drives use cases?You intend to use NFS or iscsi for the vms?
Sync or async?
I've been using mirrors exclusively for years but at this point with your use case I actually would say get an optane slog and then run z2
Those two use-cases are quite different.This machine is being used for backing up mainly (Mostly large files, and some small), might throw a VM or two on there. Only a single user.
