I wonder if my system is good or bad. My server needs 0.1kWh.

17W for an N100 system with 4 HDD's

Which HDDs? That’s really good.

Seagate Ironwolf "ST4000VN006"

I do have some issues with read speeds but that's probably networking related or due to using RAID5.

That's pretty low with 4 HDD's. One of my servers use 30 watts. Half of that is from the 2 HDD's in it.

@meldrik @qaz I've got a bunch of older, smaller drives, and as they fail I'm slowly transitioning to much more efficient (and larger) HGST helium drives. I don't have measurements, but anecdotally a dual-drive USB dock with crappy 1.5A power adapter (so 18W) couldn't handle spinning up two older drives but could handle two HGST drives.
