tbf all the big storage clusters use either mirroring or erasure coding these days. For bulk storage, 4+2 or 8+2 erasure coding is pretty fast, but for databases you should always use mirroring to speed up small writes. but yeah for home use, just use LVM or zfs mirrors.
yeah i still use hard drives for storing movies, logs, and backups on my Nas cluster, but using it for nextcloud or remote game storage is too slow. I also live in an apartment and the scrubs are too loud. There’s only a 5:1 price premium, so it’s worth just going all flash unless you have like 30tb storage needs.
Eh hard drives are archival storage these days. They are DOG SLOW and loud. Any real time system like Nextcloud should probably be using ssds these days.
they make bulk storage ssds with QLC for enterprise use.
The reason why they’re not used for consumer use cases yet is because raw nand chips are still more expensive than hard drives. People dont want to pay $3k for a 50tb SSD if they can buy a $500 50tb hdd and they don’t need the speed.
For what it’s worth, 8tb TLC pcie3 U.2 SSDs are only $400 used on ebay these days which is a pretty good option if you’re trying to move away from noisy slow hdds. 4 of those in raid 5 plus a diy nas would get you 24tb of formatted super fast nextcloud/immich storage for ~$2k.
Raid 5 is becoming less viable due to the increasing rebuild times, necessitating raid 1 instead. But new drives have better iops too so maybe not as severe as predicted.
Check out NixOS. It can build qcow images from scratch for you to import into proxmox

I have 8 bare-metal servers and I do everything automated with NixOS, I rarely ever access the servers directly.
Here are the nixos configs for my DHCP server and kubernetes servers that you can use as a base.

For what it’s worth, Ive been using Ansible off and on at work for 8 years, and I think it’s pretty outdated and clunky these days, there are much smarter ways to manage workloads such as kubernetes, cloud-init, terraform, and NixOS. If you don’t want to get into Kubernetes then definitely learn NixOS.
Kubernetes is more stable than docker compose. Docker compose is fishing for containers after the ship capsized. Frustrating and nothing works out of the box.
Yeah Stalwart seems to have a lot of momentum, I’ll probably be setting up a server with my kubernetes+ceph cluster this month.
