On an older system while you can add a PCI card to the system, in a
lot of cases you won't be able to boot off of it without motherboard
support. You can get around that by keeping a spinning drive or a
small ssd or USB crive that actually boots the system and then
immediately hands over to the root partition on the NVMe letting you
have your cake and eat it too.<br>
<br>
While a pure PCIe based card is quite expensive, you can get a PCI
card that will give you an M.2 slot for around $13 and up. The nice
thing about getting the adapter, other than saving some money, is
that most new motherboards are shipping with one or more NVMe m.2
slots, so you will be able to carry your drive over to a new
computer when you decide to upgrade.<br>

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" moz-do-not-send="true">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>
