I believe it depends on how the drives are connected.
/dev/sda would be the default boot drive, though modern computers can be configured to boot from any drive recognized by the BIOS or UEFI.
Older versions of the Linux kernel named IDE/ATA hard drives, and CD/DVD drives too, as /dev/hda, /dev/hdb and so on.
