If I'm reading this right, this device is slower than a Samsung 960 Evo across the board (http://www.anandtech.com/show/10833/the-samsung-960-evo-1tb-review http://www.anandtech.com/show/10833/the-samsung-960-evo-1tb-...). It seems that when Intel started developing Optane, they didn't anticipate how much faster NVMe PCIe SSDs would become. Couple that with significant clock frequency headroom for DDR4, and this product really doesn't look competitive.

- olavgg 10y agoYou're reading the wrong numbers. Try benchmarking with PostgreSQL's pg_test_fsync or with fio with the following options: --direct=1 --sync=1 --rw=write --bs=4k Good random-write performance with 4k/8k blocks at QD1 is what matter for SSD's, not if they can write 2500MB/s to a volatile cache.
