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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

I am smarting up my home with lots of ZigBee thingies and decided to add a ZigBee smart monitor to my selfhost setup.

Its a desktop box with a core i7 9th gen, 48gb ram, no monitor.

I used to have 4xSSD 4TB + 2xHDD 6TB. Three RAID1 for a total of 4+4+6=14Tbs.

Power was sitting at 50W.

I restructured my storage: 1 RAID5 with the 4 SSDs (12tb) and removed the 2 HDDs.

Power went down to 38W!

I am amazed.

In the future will run just 1 hdd for storing backups and keep it spinned down 99% of the time.

PS: the above wattage is during transcoding, so with high CPU and disk usage....

You've saved a whoopping 0.3kWh/day (assuming transcoding 24/7), that's surprisingly little I would say.

Power costs vary a lot around the world, depending on where OP lives every little saving can help.

Constantly turning it on/off will probably kill the disk faster than the power savings can make up for it, compared to just having it idle when not actively used.

Consumer harddisks are made to be spinned up and down occasionally. Don't do it every five minutes... But I've been doing it for years and years with my server that spins up the disks once or twice a day, once I access some of my archived files. And it's perfectly fine.

The hdd spin on once every night for backup, then off after a bit by the timeout.

That should not be a critical issue.

Yeah, most PCs get turned on and off like once per day. For example at most offices or at home. That's perfectly within normal use.
