I've got a Seagate Momentus 100GB and a 30GB drive (which I can't remember the brand of - I recall I had an incompatibility with one of the two 30GB drives I had and can't remember which I kept).

I have a lot of free space though I have a bunch of music sitting on an external drive somewhere that I haven't sent up to the empeg - 100% due to lack of time to futz with tags, syncing and organizing. I don't know if I'll upgrade the empeg again - it all depends on how full it gets and how soon that happens. I don't plan to get rid of my current empeg nor my spare, but I don't know if I'd (be able to) install either in a new car in a couple of years.

I'm planning to get a large capacity NAS box, so I may just flash one of the empegs with the receiver software as well as pick up a newer Squeezebox (though I'd love something with an optional TV-Out display).
