I have a similar situation here: The device names never change -- sda is
always the same disk etc.

This may be true in some setups/motherboards.

Others will have different experiences, e.g. when a motherboard has two or more disk controllers (e.g. one for SATA RAID and one for "regular" SATA), or you have a controller in a PCIe slot and use disks on either the controller or the motherboard, or you have several controllers in PCIe slots.
