And the wear rate on (example Samsung 960's) can be off-set by under-provisioning, and (Samsung 960's) already have a ludicrously high write-cycle life already. The most important problem is the ZFS write cache (can be several GB) that commits writes immediately to a VM but put small random data on disk with a delay of a few seconds (to increase performance as writes are not small/slow random but fast/sequential). it Fio zfs. 0x2 with NVMe - Form Factor: M. 14) boot-time loader for netfilter rules, ipset plugin iptables-persistent (1.
