While I agree with most of that shmokes, about putting games on a bigger HDD, I have to put my 2¢ in and say that I use my XBOX as my exclusive DVD player (due to XBMC awesome upscaling capabilities) and couldn't live without a dvd drive for that due to not having a server to store all sorts of movies on.
Other reasons for having a drive (some more legal than others):
Rented/Borrowed from a friend, a game which you want to rip
To play music CDs, to play cdr you may need one of the more expensive drives...
You have more games or movies than will fit on even the largest of HDDs
(related to the last one) you don't have the technical knowhow to do swappable HDDs
You're not a PIRATE and you buy games which you want to rip yourself
As for the original question,
CHECK HERE.
I doubt your drive is compatible just because the sheer number of drives that exist and the small number of drives that are compatible. Unless of course you want to do one of the setups where you hook up a PC drive in ADDITION to the XBOX drive. In which case you will not be able to close the xbox.
Honestly though, just go check out those TUTs and search the xbox-scene forums for this. There is NO better resource for anything xbox!*
