Hello everyone,
I have a DIY NAS running baremetal debian. My storage is 2x 4TB HDD in a mirror using ZFS. These drives have around 1.5 years of runtime.
I use this mirror to store irreplaceable videos/photos/documents (around 600-700GB) and host a jellyfin instance and im currently at 2.5TB for it (less important). I clearly need more storage but not sure which path to take from there.
What I currently think I could do:
-
Buy 2x 4TB drives to add another mirror to the current vdev -> "RAID 10"
-
Keep the current mirror untouched and use it only for the irreplaceable data and buy like 3x 4TB, create a RAIDZ1 with those and use this for jellyfin only. So "RAID1" for my important data and "RAID5" for the less important movies/shows.
-
Completely convert to a RAIDZ1 after buying 2x 4TB drives to store everything on it and get more data with this type of raid. (So 4x 4TB "RAID5")
-
Still open to use something else than ZFS if it would benefit me in this situation.
Let me know what you would do and if I didn't miss anything.
Note that I do value the possibility to expand my storage in the future, could be by adding more drives OR by replacing existing drives to a higher capacity.
And FYI my case can hold 8-10 HDD and my motherboard has 6 sata ports. Thankssss
