See if it reads, see if it writes. Whatever software you think you'll be using with the Premium, run it through all its paces. If you'll be using it to burn audio CDs, go through your normal workflow & see if the CDs work on other devices. If you'll be using it for ripping, again, run it through the normal workflow & see if it completes without error. That's the best test.
Might also help to see if software like PlexTools works, if you intend to use it.
