I know there was an older post about RaidZ vs Mirroring for hard drives. I'm fairly certain those were large drives too so I apologize if the logic is similar for my scenario!
I have three 120GB SSD and i'm trying to determine what the best setup would be for moving my jails(plex/sab/sickrage)/.system files over to it.
While it's my understanding that mirroring provides performance at the cost of a higher risk factor.
RaidZ would be essentially the opposite at a higher cost per GB, less performance, with smaller risk depending on if you go Z1/Z2/Z3. I also think I read something about a small failure time for SSD especially those that are small in size.
I have 6 x 2TB WD Reds in a RaidZ2 config. So i'd like to keep everything sensitive on the Z2 Pool.
There's one thing i'm really not sure about still:
2 SSD for Mirror?
2 SSD for RaidZ1 with one of those being redundancy
3 SSD for RaidZ1 with one as redudancy and the third as a speed boost? Does it work that way? and is it even close to the efficiency of a 2SSD Mirror?
If I were to run a 2SSD Mirror could I schedule snapshots of the .system/plex/jails files to restore from in the event one or both of the SSDs fail destroying the dataset/mirror. Or will I be S.O.L ? I'm not 100% on taking snapshots on one dataset/pool and storing them on another pool.
Some insight would be greatly appreciated. Perhaps I need to RTFM harder or take another round on Cyberjock's PowerPoint that talked about Datasets/Volumes/Pools.
