if you are building a 10TB ZFS proof of concept NAS with 1GbE networking, the Intel Optane Memory 32GB M.2 drive is an enormous upgrade over SATA and SAS devices in the sub $100 category if you can live with the lower endurance and reliability ratings.

As we have tested the device and had both it and the M.2 version in our lab for some time, the question is whether it is worthwhile. Since 1PB written would be about the maximum we plan for on low-end storage server equipped with only 10GbE, the Optane 900p/ 905p we see as a better value. They are faster and higher capacity with a lower cost per GB.
