    Question Nvme ssd

    Does Linux\Ubuntu supports NVME SSD well? Like if I install the OS on that disk.
    Is getting NVME SSD vs regular SSD worth the price? what's the pros cons? (thinking about buying Samsung 2TB NVME SSD for the new PC).

    Re: Nvme ssd

    I have 3 nvme ssd:s on this computer. None that big. I have 1 with Fedora 32, 1 with Ubuntu 20.04 and 1 with W10.
    Nvme1 is installed on a Delock PCIExpress x4 card. The other 2 are installed on the motherboard's nvme interfaces.
    Performance is cheched with the Disk utility.
    Average read rate on Nvme0 is 1,6 GB/s (100 samples)
    Average read rate on Nvme1 is 1,7 GB/s (100 samples)
    Average read rate on Nvme2 is 3,0 GB/s (100 samples)

    I have had no problems so far.

    My machine has two, a 512Gb Samsung 970 pro that holds operating systems and the system ESP and a 2Tb IBM P660 that holds user data (separate partitions for Windows and Linux docs and pics,) that I bought on impulse when NewEgg offered them on sale $150. Both work fine.

    It depends on your computer's UEFI firmware. You may need to upgrade the firmware to use the NVMe and to boot from it. Check with manufacturer for details.

    To support NVMe booting on my Asus h97 motherboard (2014), a firmware update was required. After that, it works.

    I too have an NVMe on my desktop, HP 920 512GB. It seems to work as advertised. I'm not sure though how much of a benefit NVMe is on an ordinary desktop machine. My impression is that NVMe really shines in continuous high throughput situations such as servers or cloud infrastructure. Another benefit of NVMe is size, they're small for compact devices. My impression could be wrong, I'm not a pro.
