I’m guessing it’s for some shit to make sure some ridiculous setup with two gazillion drives doesn’t have conflicts

I’m not sure if it is the standards one or the usecase one

The other dragons aren’t specifying a partition

So the 3rd dragon should just be /dev/nvme%d

NVMe device names follow this pattern: nvme <number> n <namespace> , where: <number> is an integer that is assigned by Linux during the boot process. The first NVMe device that is detected is assigned 0

I still don’t understand the point of namespaces. I guess it’s less overhead to pass through a namespace to a VM rather than having a virtualised disk image or bind mount.

You also can have a ‘c’ in there, when it wants to model multipath nvme…

Well it’s sdx because they both use the SATA interface. The sdx convention actually comes from scsi though, and the fact that SATA and USB drives use it might point to some code reuse, or maybe a temporary solution that never got fixed due to breaking backwards compatibility.

Fun fact: IDE drives use the hdx naming convention.

I thought they standardized on sd* even for IDE drive a few years back…

Yeah, that’s what I think as well…

Got a few old rigs with IDE drives in them running Void x86, the drives in /dev are named sdx.

I didn’t know that. Maybe nvme hasn’t been added to the standard yet then.

No, they decided that nvme were too fancy to be modeled by mundane ‘sdxn’ scheme. They hypothetically have ‘namespaces’ and ‘controller paths’ and they wanted to have the naming scheme model that fully.

I still muscle-memory type /dev/hd[TAB] once in a while when looking for storage devices.

Yeah, but I think they switched to also use sdx for IDE devices as well.

Virtual drives also have a fun and relevant prefix!

Yea, I get that the s in sdX stands for sata, but why cant we have an ndX with n for nvme?

Different bus, different naming.

Now, memory kinda hazy, but weren’t ide devices /dev/hdX?

Yeah, they used to be, but they switched a few years back to consistently call all block devices sdx.

srsly? so it’s just all “grab whatever dev” and not at all associated with the bus?

ATA was rolled into the SCSI subsystem, so both sata and pata are covered by SDX.
