Actually 40gb is overkill, but you'd be hard put to find one today, or
even an 80.

It could be argued that a larger drive will give faster seek times, if
the data is properly arranged, because it doesn't have to seek but a
small portion of the total, but I wouldn't put too much stock in that
argument. The geometry that's perceived by the OS probably has nothing
to do with the actual physical location on the platter stack.

Actually, the solid-state drives are getting cheap enough that one might
want to consider one for the OS, but if you have a lot of RAM it's
buffering most of the often-accessed stuff anyway. Myth users usually
don't care about faster startup speed.

As for the DVD drives, I'd think you would want those to be on the
frontends, where the viewer can access them, and nobody I know can watch
more than 1 DVD at a time, so I'd stick with the single drives.

Or, assuming you live where it is legal, you could rip the DVDs and
store the data along with the recordings.
