Hey...
I just got a new laptop, and I am in the process of setting up opensuse on it. For the moment it has tumbleweed, but I plan to set it up with 15.3.
One thing I noticed is that the new hard drive nomenclature, or whatever you should call it, is different from what I am used to in the past. In the past the drives would be /dev/sda, /dev/sdb, etc.
In this one, if I plug in a USB stick, the drive letter is /dev/sda. However, the NVMe SDD that I put in it was given the designation /dev/nvme0n1, with each partition being /dev/nvme0n1p1, /dev/nvme0n1p2, etc.
This is the first time I have had an NVMe SSD, but when I set up the partitions for the install, I didn't know that it would give it these kinds of letters.
I am just curious as to what the reason was behind the decision to change the way drives are designated if they are NVMe, and if any other changes like that have been made? AFAIK it's simply because these NVME SSDs are PCI devices, like for a while we had /dev/hda for an IDE device, /dev/sda for a SATA device. This notation is clumsy. Someone should find a better notation--how about /dev/sfa where the f stands for "flat"? Or something similar. --doug
