This is the first I've heard of NVMe. I just read
https://en.wikipedia.org/wiki/NVM_Express , and now have some questions:

1) Can I replace the spinning platter 2.5" hard disk in my 5 year old
   laptop with an NVMe device? My research tells me an NVMe must plug
   into a PCIe slot rather than a SATA slot.

2) Do you fstrim NVMe-hosted partitions the same way you do for SSD?

3) When you install an NVMe card in a PCIe slot, what device name shows
   up? Is it sd-whatever, or something else?

4) If my desktop has a free PCIe slot, does that mean I can plug in an
   NVIe drive and use it?

Thanks,
