Just like
@Mikael H points out, Windows drive names are quite arbitrary in their naming convention while Unix-like OS's are more logical.
Take a standard hard drive for example in a computer with 2 of them:
- First HDD = sda
- Second HDD = sdb
Now let's talk partitions with one HDD in the computer and 3 partitions.
HDD = sda
- Partition 1 = sda1
- Partition 2 = sda2
- Partition 3 = sda3
Let's see a computer with two HDD's and partitions.
HDD one = sda
- Partition 1 = sda1
- Partition 2 = sda2
- Partition 3 = sda3
HDD two = sdb
- Partition 1 = sdb1
- Partition 2 = sdb2
- Partition 3 = sdb3
If you have two CD/DVD ROM drives they would be:
- First ROM drive = sr0
- Second ROM drive = sr1
You can use the command below in a terminal to see drive layouts.
If you just want to see your drives without displaying the partitions:
For example, here is the computer I'm on right now.

The first HDD is
sda and the first m2 NVMe drive is
nvme0n1. I have it configured that the nvme0n1 is my boot drive and the HDD as a secondary storage device.
Here it is again showing partition layouts.
