NEC D3146H
A fairly rare drive, but one of the very best pre-IDE drives around. The 3146 was fast and very reliable. It was the last ST-506 (pre-IDE) drive we ever sold, and was every bit as good as the three early IDE steppers described next.
NEC kept on making pretty nice hard drives, by the way, for a good long while after this; but eventually switched to just manufacturing under license from IBM for a while before giving it up altogether.
