SSD longevity seems to be better than HDDs overall. The limiting factor is how many write cycles the SSD can handle, but in most cases the write endurance is so high that it’s unreachable by most home/NAS systems.
SSDs are however really bad for cold storage, as they will lose the charge stored in their cells if left unpowered too long. When the SSD is powered it will automatically refresh the cells in the background to ensure they don’t lose their charge.
Nope, those steps are the steps needed to legally watch Netflix on Asahi Linux on an Apple Silicon device, because Google has not officially released the widevine library for that platform
But the author is actually using less data than expected, because he’s paying for 4K, but only able to watch up to 1080p
My home-assistant installation alone is too much for my Raspberry Pi 3. It depends entirely on how much data it’s processing and needing to keep in memory.
Octoprint needs to respond in a timely manner, so you will want to have the system mostly idle (at least below 60 percent CPU at all times), preferably octoprint should be the only thing running on the system unless it’s rather powerful.
If I were you, I would install octoprint exclusively on your Raspberry Pi 3, and then buy a Raspberry Pi 4 for the other services.
I’m running Pi-hole and a wireguard VPN on an old Raspberry Pi 2, which is perfectly fine if you are not expecting gigabit speeds on the VPN.
This is pretty cool, but I’m wondering why… Sure there’s lots of systems that make use of A/B partitions, which is a pretty good move, but with BTRFS you could have it all in one partition with an A/B subvolume, and they would even be able to share extents that are common between the two (meaning drastically reduced disk space requirements), while still maintaining the ability to boot into either…
Depending on how much changes you might even keep many more than just two subvolumes. On my machine I run BTRFS with snapper, which takes periodic snapshots, as well as before and after every time I install or uninstall a package, with the ability to boot into any of the snapshots if a change somehow botches my system.
While shorter lived certs certainly improve the general security, certificate revocation lists are what you need if a cert gets compromised.
Wait until you set up cert-manager to issue both Let’s Encrypt certificates, as well as generating your own CA and issuing certs from your own CA where you can set the validity however want.
ZFS doesn’t really support mismatched disks. In OP’s case it would behave as if it was 4x 2TB disks, making 4 TB of raw storage unusable, with 1 disk of parity that would yield 6TB of usable storage. In the future the 2x 2TB disks could be swapped with 4 TB disks, and then ZFS would make use of all the storage, yielding 12 TB of usable storage.
BTRFS handles mismatched disks just fine, however it’s RAID5 and RAID6 modes are still partially broken. RAID1 works fine, but results in half the storage being used for parity, so this would again yield a total of 6TB usable with the current disks.
