The ST01 will work with non-Seagate drives, but you may have to bypass
the onboard ROM which makes it look like an XT/AT drive, and you will
likely have to write your own driver. An ST01 driver for Microport Unix
that works with non-Seagate drives was posted several months ago. It
appears that the Seagate-specificity concerns some assumptions made in
the ROM routines. There are apparantly some shortcuts taken in the
ST01's electrical interface, but these are not the major problem, from
what I hear.

The ST01 is reportedly made for Seagate by Future Domain. The  onboard
ROM carries a Future Domain copyright. So, they may make the best host
adapters, but they also make the ST01.
