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.

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.
