Originally I'd used 2xUSB boot sticks with an encrypted data pool which meant I had no real option but to keep System on the data pool and use a key without password so that System is available at boot time.
I've since migrated my boot drives over to a mirrored pair of Kingston SSD M2's (120GB) and upgraded to TreeNAS 12. Which now means password protected encryption without the need to manage a key is an option. However, the catch is, if you use a password (and thus derived key) for the pool, the System dataset restriction kicks in again. So...
Are there any concerns with moving System to the M2 boot drive? Just how much data gets written to System each day and what is it? I believe the drives are rated for 40TB minimum lifetime writes. Also any issues with regards to FreeNAS usage? What would happen if I lost both boot drives and reinstalled + restored config from backup (or made a new from scratch), just what would have been lost from within that System dataset?
