Scorpio Black vs Caviar Blue

I have Scorpio Black ( WD3200BEKT) from my Laptop

Now building a Desktop. Do you recommend to use Scorpio Black using 3.5in Adapter or Get a Caviar Blue ( WD7500AALX)?

Which will be good in term of performance?

Caviar Black is coming with 32mb So that is a clear winner but That is not the Question

Are 2.5in are more Durable than 3.5in in term of shock proof?

I know 2.5in are power efficient but i don’t want to get with the expense of performance


WD Black as they named now is the clear winner on this.
