I'm a huge fan of Glyph drives. They are dead quiet and totally reliable. They come up to 750Gig.

The GT050 drive has FW400 and a FW 800/400 and eSata version. I have never had a problem with any of the ones I've owned.
I know of some who have had good success with Firmtek eSata drives as well.

But they are only eSata so you wouldn't be able to share the drive as easily as the Glyph with 4 different connectors.
Of course, they come with a premium, but i found it worth it.
