Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

For power consumption, NVMe drives use quite a lot of power, especially PCIe 4.0 ones. About 5W each during use.
3.5" HDD (especially 7200rpm or more) also consume significantly more than 2.5" 5400rpm HDDs that are optimized for low power (the latter use about 1W during use).
SATA SSDs fall somewhere in the middle.
I'm surprised to hear NVMe us that much power - I had no idea, and just assumed they used very little.
It sounds like from a power perspective that 2.5" is better, and SSD is lowest power?
They use practically nothing when idle, but it spikes up dramatically under heavy load.
Still much less on average than a HDD that uses 5-10W even when idle and spun up.
