i just want to know which has the best overall performance ,
price is not an issue.
Get the Seagate 7200 rpm, then. Could be issues with heat, but no one has experience with it in the wild yet. I went with the Samsung for this very reason - very little heat generated from it.
are there any 7200rpm 500GB ?
i don think so .
i need 500GB
and as far as i know there's only 5400 rpm available for that capacity for now.
THere aren't any 500g notebook drives @ 7200 rpm, only 5400. Go with the western digital.

Actually, you implied it could be found in the wild and I suspect that it hasn't shipped yet. It's out of stock at every vendor where it's listed - zipzoomfly, buy.com, etc. Do a google shopping search on the part number and all the vendors who have this product are out of stock or sold out (st9500420as). That's fairly normal behavior for products that aren't shipping yet.
That may be true - but its arrival is clearly impending and may be worth the wait. But considering Seagate's recent 1.5TB adventure, I'm not sure I'd want to be one of their "beta testers".
