You mean that *so far* your internal hard disk is always /dev/sda
and *so far* your external USB disks are always /dev/sdb and /dev/sdc.
There are no guarantees that it will always be so.
On my system, I've noticed that my single internal hard disk is
usually /dev/sda and my CD-ROM drive is usually /dev/sdb.
But if I boot my system from a rescue CD, the CD-ROM drive
is usually /dev/sda and the hard disk is usually /dev/sdb.
But I cannot guarantee that the hard disk will always be /dev/sda
even if I boot from the hard disk every time.
It's all timing dependent. Devices are not necessarily discovered
in any particular order anymore. It is safest to use UUIDs
