Look for 5W idle consumption boards + CPU combos which go down to package C6+ state. HardwareLuxx has a spreadsheet with various builds focusing on low power. Sell half your disks, go mirror or Raidz1. Invest the difference in off-site vps and or backup. Storage on any SBC is a big pain and you will hit the sata connector / IO limits very soon.
The small NUC form factors are also fine, but if your problem is power you can go very low with a good approach and the right parts. And you'll make up for any new investments within the first year.
Thanks! I need to look more into what the power implications of 8 drives is - they never spin down, so I assume they are a non-trivial portion of my power consumption.
That said, I've been considering upgrading to something recent and low power anyways. It would be a good opportunity to sneak in some useful features too,
Which the old hardware wouldn't support without adapters, cards, etc.
Responding to myself...
Datasheet reports 7.05 idle watts (~11w at active random read) so depending on what it considers idle, it'd be 8*7.05|11= 56.4:88W
Server clocks in at ~102W. Halving the drives would reduce the power by 27 : 43%
And in theory other components (motherboard, CPU...) must be using anywhere from (102-88) :(102-56.4)= 14 : 45.6 W.
Oh okay that's a lot of power. For reference, I just set up an old Haswell PC as a NAS, idling at 25W (can't get to low Package C states) and usually at 28-30 running light workloads on an SSD pool. My plan was to add a 5 disk cage and at least 3 HDDs, with Raidz2 and 5 disks being the mid term goal. Absolutely unnecessary and a huge waste. I settled on less but larger disks, and in mirror I can get 12-18 TB usable space for under 500€. Less noise and power draw too.
