I've been doing a lot of reading about ZFS, FreeNAS, and the pro/con of various drive configurations. A lot of my early planning hinges simply on selecting hardware, making sure I have a case that can accommodate all the disks I want/need, etc. With that in mind, does this seem like a reasonable growth plan?
On a related note... I've been playing with ZFS raid pool calculators online and it seems like your overhead desceases significantly as you build a larger pool. (e.g. a 4 x 4TB Z2 array is 50% overhead but a 12 x 4TB array is like 23% overhead). What's the story there? How risky is it to build a bigger pool with numerous disks?
- Phase 1:
- Set up a RaidZ3 (5x1TB) for family photos (and critical documents)
- Set up a RaidZ2 (6x3TB) for media (movies, tv shows, etc.)
- Phase 2:
- Set up additional RaidZ2 pools as my storage needs grow.
