for a given generation of disks, larger disks have more platters,
which require more energy to start up. They also use a bit more while
running, but the difference will be small - probably less than a watt.

I think the latest 3.5" drives use 500GB platters.

I managed fine (24 and 27) - got some sucker things off ebay, and a can
of compressed air (to blow the inevitable dust from the screen), and
some decent torx screwdrivers. Be wary of the guides - they get you in
the ballpark, but I've found differences in screw counts/locations.

I'm pretty sure that all but the latest use a stick-on HD temp sensor.
If it's later, you'll need a disk of the same make with appropriate
pin-outs for the sensor. The 320 in my 24" is the quietest HD I've used,
but it's quite hard to get an exact copy - ebuyer were doing them
rcently I think.

I swapped it out for a 1TB WD 'Green' (lower power, heat and noise) and
it's pretty good. Not quite as good as the 160GB SS :-)

Fnarr! Second one in this thread, well done.

(though using post-its to make notes about the screws surely kills the
moment?)

Seconded. For me, (lack of) noise is more important than speed or
capacity and I always seem to end up with either Western Digitals or
regrets.

It depends on where you put it.
