Actually, it really depends on the amount of power each drive uses, and the
amount of heat it generates.  If you had a 207 MB drive that used the same
or less power, and generated the same or less heat as a 104 MB, there would
be no reason you could not put two of them in an SS1.

However, I suspect for most people, they are talking about the specific model
of drives that Sun ships, which are Quantum ProDrives for the 104 MB, and
either a Quantum ProDrive or a Maxtor LXT for the 207 MB (at least in the
machines we've gotten through here).

I don't know about the Quantum 207 MB, but it is true that the Maxtor
puts the SS1 power supply right at its crumbling edge with two of them
stuffed in there, and I also know the Maxtors tend to run hotter.  Whether
that's too hot, I don't know, since I haven't done any real calculations.

Note also that later model SPARCstations have better power supplies, and
the SS2 has an auxilliary fan in the drive area.
