Switched to ZFS recently for my home server, 6x8TB SATA Raidz2 (data) and 4x 500GB SSD SATA Raid1 Mirror (VMs). Above everything, resilience, predictability and piece of mind were the primary motivations. The performance is totally fine - many argue against slow SATA disks with ZFS, especially SSDs, due to ZFS impact on Total Bytes Written (TBW), but if you're not hosting an enterprise with many Database writes, SATA disks are perfectly acceptable with ZFS (my observation). After one month, I have accumulated 2 1/2 TBW on the SSD-Mirror - the disks would still last about 7 years given this rate (this is running with 25 Docker Services and 5 VMs, including bigger ones such as Gitlab). I have compression and encryption on and the fio benchmarks were all good, similar to what I saw with the Hardware Raid 1. Regarding monitoring: It is not that difficult. (1) Have ZFS Mail status updates to you (e.g. this is the default in Proxmox), (2) Monthly Scrubs (cron) (3) Monitor TBW with (e.g.) InfluxDB. Wrote a blog post about the last part [1] "Disk Wear (SSD) - extracted from extended Smart Attributes (Single Stat)". All of the issues with degrading disks apply equally to other disk setups (e.g. Raid1). However, ZFS gives you better tools to predict and prevent, before disaster happens.
