I don’t plan to neglect backups. Currently I use Syncthing as well, but only between non-redundant storage locations, so I have duplicates. Like phone pushes photos to pc or laptop, those sync them between each other. Important docs that I can’t lose are also on all 3 devices.
And I plan to keep the local storage of mission critical data around on some clients at least. I just want to have a central, more robust, redundant system where one or 2 disks can fail without my data being gone or corrupted.
An interesting take, and not very popular among the other comments, but I suppose you have your experiences and reasons to say this.
As I mentioned RAID is on the table, no problem with that. It is kind of the point to have a safer, more centralized storage for important stuff, and space for keeping media.
Speed wouldn’t be a concern. Noise is, since my apartment is very small. And reliability over time would be. Especially power cycles, or spin down - spin up events. I figured if I used SSDs, I could leave the whole rig powered on 24/7 But with HDDs I think I would probably need to turn the system off for the night.
Correct me if I am wrong about enterprise grade SSDs, but if I have the power on time and the TBW values for the drives along with the manufacturing date, ones with reasonable combination of those could be bought for a reasonable price. After some testing they could also be trusted. At what point would you expect an SSD like this to last some years in a home server environment? I am not an expert but with some pointers this should be easy to figure out, which is why I am asking.
