SMD drives [...] going from dozens to hundreds of
megabytes
The largest I met were 8" Fujitsus that were in the 2 Gbyte range.
If we want to get into the "drive interfaces that were the next big
thing but never quite caught on in the wide world", we can start
talking IPI :-). I've seen VME and TurboChannel IPI interface boards.
We may still have some dead IPI drives in a chassis at work...
IPI cabling looks a lot like SCSI cabling but that's about all I can
say about the interface standard.
