If it's recording the same stream it'll use the same amount - here in
Australia, MPEG2 HD uses about 7GB an hour, or roughly 140 hours per
TB.

Look up the benchmarks on 2TB 5400RPM drives - for many applications,
the higher data density renders the lower rotational speed moot. I
wouldn't run an OS or database on one, but for dumping recordings onto
they're fine.
They're also rather more economical....here in Australia I can buy
WD's, Seagate's, Samsung's or Hitachi's for ~$110.
