The Hawk was quite different from the Phoenix. Actually it was not a
Cartridge Module Drive, rather it was called Cartridge Disk Drive. While
the CMD and SMD drives could be used on the same host interface the Hawk
could not since the interface was different from the SMD interface.
I don't know that I recall SMD being a
product as much as a reference to
the interface they had though.
"SMD" was in fact a product name. The CDC976x, BK4XX, BK5XX, BK6XX, and
BK7XX series drives had the official name "CDC(R) Storage Module Drive",
from whence came the "SMD" name for the interface, starting with the 9760
in 1973. MMD and CMD drives came along a few years later. AFAIK the MMD
drives weren't too popular in the early years, but gained traction in the
1980s. CMD drives, on the other hand, were an instant hit, starting with
the 9427 "Hawk" drive in 1977.
