I had similar idea, but in the end I've gone a different path:
I've got a USFF PC with 2 external HDDs as NAS, and raspberry pi to keep always on stuff. I used to keep the PC up most of the day, and get it to sleep on schedule during night with `rtcwake`, and it was pretty reliable.
I've removed the scheduled sleep from the PC, as I prefer backups to be done at night, and my "minilab" of USFF PC with SSD & 2 external HDDs, rpi 4 with SSD and a 1Gb switch uses 18W idle, according to cheap power mater.
USFF PC is ThinkCentre tiny m93p with 2-core 4th-gen i5, and I guess newer models should fare better with idle power use.

- aljarry 3y agoI've got 2 external HDDs in ZFS mirror, cheap consumer disks. One of them is perfectly fine, second one started having occasional read or write errors, which is not great. With regular weekly scrub I hadn't had any data issues over last 3 years, and I'm pretty happy with the setup. But it's a hit or miss with consumer external HDDs - before that, I used a single external HDD for backups at a time (100-200GB writes a week) and I lost data from 2 cheap external HDDs over span of 3 years.
