This is the first I've heard of NVMe. I just read<br>
<a href="https://en.wikipedia.org/wiki/NVM_Express" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/<wbr>NVM_Express</a> , and now have some questions:<br>
<br>
1) Can I replace the spinning platter 2.5" hard disk in my 5 year old<br>
laptop with an NVMe device? My research tells me an NVMe must plug<br>
into a PCIe slot rather than a SATA slot.<br>
<br>
2) Do you fstrim NVMe-hosted partitions the same way you do for SSD?<br>
<br>
3) When you install an NVMe card in a PCIe slot, what device name shows<br>
up? Is it sd-whatever, or something else?<br>
<br>
4) If my desktop has a free PCIe slot, does that mean I can plug in an<br>
NVIe drive and use it?<br>
<br>
Thanks,<br>
