I am still trying to understand the smartctl(8) "SMART Attributes Data Structure".  The RAW_VALUE seems to be a binary bit field (?)

same here

some makes/models of hardware seem to produce a greater quantity of comprehensible smart data

I run like
# smartctl -x /dev/sdf
returns additional data.


Twelve disks gives you many choices for how to layout the pool and trade-off redundancy vs. capacity vs. performance.  Is the data balanced across disks?  Does the machine have enough memory?  Is the ARC working well?

It has 256GB RAM.

My desktop pc currently has only 1Gb networking ever since I replaced my fiber optic card with a gpu in the lone PCIe slot. During the time I had 10g networking direct from server to workstation, I recall easily saturating the network. Amazing speed, but I needed the gpu more. 10g networking is faster than the cheap SSDs in most of my PCs.
