[Ti] 4200 vs. 5400 rpm int. hd: decision?

[b]

According to Dick Grable:

The speed increase between the two is negligible, however the 
difference in heat generated [think Laws of Thermal Dynamics] is a 
different story. The heat situation is more relevant to the mean time 
between failure of the drive itself, not the Powerbook.

Video work, if we're talking about non-linear editing, is best done 
on an ultra wide SCSI [10,000 rpm is nice], but that's a bit extreme 
for most non-pro video editor-types.
