- I'm just guessing, but it may be that the internal version doesn't get
- as hot since it's typically housed in a PC case that has forced air
- cooling. The external, on the other hand, is sealed in a little
- plastic box which may or may not have good airflow (depends on how
- much effort went into its design - I haven't had much experience with
- USR externals). Secondly, the circuit board on the external may be
- layed out slightly differently than the internal, which might cause
- things like subtle timing bugs that are more heat sensitive than on
- the internal version, etc.
-
- Again, this is just idle speculation.
