That explains why circuit city has a Toshiba with 320GB but 5400 rpm.

I don't know if any laptops come with 320GB @ 7200rpm. But they do sell
them and will fit a laptop.

I have not seen a laptop drive that large, period. I do know that two
manufacturers announced 320GB drives just in the past 2 weeks, not
shipping just yet but imminent. However, I don't think that they were
7,200 rpm. In these smaller drives, there is a "lag" compared to
desktop drives .... they are neither as large nor as fast, and there is
a tradeoff near the top ends of the performance and size ranges between
rotational speed and capacity .... you have to give up one to get the
other. Over time, they keep getting bigger and faster, but they are
always behind desktop drives, and at the top ends of the speeds and
capacities, there is always a tradeoff, you can't get the fastest speeds
(7,200 rpm) in the largest sizes.

Weird... your Internet access must be different than mine. As if I
Google 320GB, 7200rpm, 2.5 inch, I get ½ million hits. Here is one of
them.

I didn't google. I looked at laptops at Circuit City sites, not hrad
droves and saw that their product G45-AV680 and X205S9359 at $3500 was
with 320GB of 5400 rpm.
