If you set up the system pool as RAID 0 instead of RAID 1, the main risk is that if the SSDs fail, you won't have redundancy, and you'll lose the system pool. However, your data on the HDDs in RAID 6 would not be affected, as RAID 6 is independent of the system pool. You could replace the failed SSDs, reconfigure the system pool, and rebuild the NAS, but the process would require reinstalling QuTS Hero and reinitializing the system pool.
The benefit of using RAID 1 for the system pool is redundancy: it provides protection if one SSD fails. While RAID 0 gives you a little more speed and usable space, you risk total data loss on the system pool if an SSD fails, as there's no redundancy. For a NAS where uptime and data safety are important, RAID 1 is generally recommended for the system pool, especially if you're using it for system-critical tasks.
