small and fast is all you really need to worry about

if you can find a 10,000rpm model that would help but might be a bit noisy for your tastes

160gb is plenty (80gb would be easily be fine)

Yes that one you linked to will be fine. But the general rule of thumb is that the larger the images/files you intend to work with, the bigger your scratch disk should be.......

Of course this wont matter unless you:

A) Have sufficient Ram to dedicate to PS in the 1st place, AND....

B) You have set the PS prefs to use the right amount of ram (approx 60-75% of total) and identified the scratch drive(s) in the prefs :)

ps....I use a 10k/150GB Raptor notta problemo for avg 100mb-20GB images........
