metoo had that unpleasant experience of a worn out SSD that had been used as a ZFS cache and zil device. After that, my next comp got huge amounts of ECC-RAM, freeing up the SSD for the OS and stuff. Also i did change the geometry of the main pool to a collection of mirrors (much faster than raid) and left the raid only on the slower backup server. Due to snapshots and increments, i am now backing up only once in 2 weeks, which takes somewhat around 1 hour bcoz of a slow connection. But i am satisfied with zfs performance from spinning rust, if i dont fill up the pool too much, and defrag after a while ... ;-)
