I've printed, another 2 trays with 2 ea 4T SPCC drives on those 2 trays, 
another tray with one more of these 4T drives in the bottom of tray 3, 
and a 250G toshiba lappy drive of spinning rust as the 6th, holding disk 
drive. Topped with a 5Vx20A PSU, and an 8 port usb-3.2 hub glued to the 
side of the cage, powered by that 20A supply, big PSU because the SPCC 
drives use 4 amps to write, burning up the 2amp hub supply.

I have just plugged it in and booted it to armbian nobel. dmesg reports 
only one drive having a partition, sde1, the rest are as shipped.

I want to set this up as an 8T raid using the 5th drive as the parity 
track, and the 250G toshiba as holding disk.  What tools do I install, 
and how do I configure it?

Or at 4 amps per drive writing , is that beyond my power budget?

Thanks for any guidance.

Thanks for any guidance.
