I've not had any problems with them. They do show up as a different device: |
8 |
|
9 |
/dev/nvme0n1p# |
10 |
|
11 |
Where # is the partition number. I think /dev/nvme0 might be the first |
12 |
NVMe controller as the only NVMe (card?) that I have is /dev/nvme0n1. |

I've been using the inexpensive ~> cheap one that I have for more than |
17 |
18 months. I'm using a partition on said NVMe as a cache for my ZFS |
18 |
pool. I've not yet seen any symptoms of problems. |

I will say, that you want to make sure the system has PCIe that's 3.0 or |
21 |
better to take advantage of the full speed. -- My existing NVMe is in |
22 |
a PCIe-16x slot to NVMe adapter card. It only uses 4x lanes, but the |
23 |
other are physically occupied holding the card. |
24 |
|
25 |
I'm building a new system, to replace the 5+ year old XPX w/ PCIe 2.0 |
26 |
that has the card and I'm replying from with a newer system with quite |
27 |
similar, save for PCIe 3.0. The speed difference between the NVMe in |
28 |
the systems is insane with the faster PCIe bus. |

32 |
That depends. |
33 |
|
34 |
If they are used for part of the operating system, as in your boot / |
35 |
root drive, then simply disabling them will be ... problematic. If |
36 |
however, you are using it as a non-essential drive, or not using it at |
37 |
all, then sure, you can disable it. |
