Hello everyone: I built a new machine with a Samsung SSD 960 EVO NVMe <https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwjWxp_rk8nUAhWBfn4KHadiANoYABABGgJwYw&ohost=www.google.com&cid=CAESEeD2DLyQ7hEOLOBgSPqc9iEd&sig=AOD64_35gPrHU2xXVzC269PD9qfp0UjlwQ&ctype=5&q=&ved=0ahUKEwi6nZrrk8nUAhUE42MKHXAuDBsQww8ILA&adurl=>Samsung SSD 960 EVO NVMe <https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwjWxp_rk8nUAhWBfn4KHadiANoYABABGgJwYw&ohost=www.google.com&cid=CAESEeD2DLyQ7hEOLOBgSPqc9iEd&sig=AOD64_35gPrHU2xXVzC269PD9qfp0UjlwQ&ctype=5&q=&ved=0ahUKEwi6nZrrk8nUAhUE42MKHXAuDBsQww8ILA&adurl=>Samsung 950 EVO NVMe M.2 500GB component. Installation went swell. I was able to use bootctl (by whatever name), which seemed to be easier than using GRUB. (on the Manjaro wiki was found an extremely coherent discussion of this system). I have encountered no problems other than slow-ish (if one would call it that). When I run hdparm to test the performance of this memory, it falls far short of the specification of 32 Gb/s. I realize that the Linux kernel has recently included some code for the NVME drivers. There is also some question as to the best parameters to use in /etc/fstab. So I am requesting assistance to set up this device on this mailing list. I am using the Zen kernel. Some checks I have made: # hdparm -Tt --direct /dev/nvme0n1 /dev/nvme0n1: Timing O_DIRECT cached reads: 2404 MB in 2.00 seconds = 1201.67 MB/sec Timing O_DIRECT disk reads: 5372 MB in 3.00 seconds = 1790.16 MB/sec # nvme get-feature -f 0x0c -H /dev/nvme0n1p2 get-feature:0xc (Autonomous Power State Transition), Current value:0x000001 Autonomous Power State Transition Enable (APSTE): Enabled Auto PST Entries .................
