Actually, there are a number of manufacturers of removable mechanisms
(Bernoulli, Syquest, and Ricoh are most popular).  Each of these mechanisms
have their own advantages and disadvantages.  Syquests are cheapest and
most common, but are relatively unreliable, causing a number of companies
in the Mac market to avoid or drop them.  Ricohs are a new technology
which promises to be quite reliable, but are also more expensive.
Bernoullis are the most expensive, but are an established, reliable
technology.  There are also more "exotic" technologies such as
megneto-optical drives, flopticals, and so on.

Those mechanisms are used by a large number of companies, who add a case,
power supply, cables, driver software, documentation, and perhaps other
bundled software.  The other factors are how much testing the company does
on the mechanisms it ships (to weed out failures), the quality of their
engineering, and the warranty and service that they provide.  While some
companies may just be "the maker of the housing" there is a lot more than
that going on at any quality drive vendor.
