Sony :: How Can I Check If My Notebook Supports SATAII

I'm thinking about changing my HDD, since it's a 4200rpm 200GB.

I was thinking about getting a Samsung SATAII 7200rpm( storage doesn't matter that much, I already own an external device, as long as it's not less than my current HDD ).

But I was told that my Vaio model, VGN FZ140E, doesn't support SATAII. So I'd have to choose a SATA 5400rpm HDD.

I'd like to ask you how can I check it this is true. If so, would changing my HDD be a noticeable upgrade?

Also, among these brands, which one would you choose( for better performance, low noise, low energy comsumption etc. ): Samsung, WD or Seagate?
