[kwlug-disc] TrueNAS scale (4-5 drive configuration)

[Charles M]

Thanks Cranky, I did in fact build a TrueNAS machine to back up existing
data (on 4 x 3TB) on a Dell T110. So once the new machine is built I'll use
that machine to copy data to the NAS. It may be a while before I back up
the new machine, drives are still a pretty penny. Hopefully SSDs will drive
the price of spinning rust drives down.
