Largest Single Platter drive?

Hi,
Need to replace my hard drive in my HTPC as it's started developing bad sectors.
Anyway being that it's for a HTPC I want it to be as quiet and cool running as possible. Either going to be a seagate or samsung, however what's the largest I can get with a single Platter drive?

Many Thanks...

excuse me for asking a stupid question, but why would the number of platters make a difference?

My understanding is that less platter means fewer moving parts, which means less noise, heating etc
