I need a hard drive



In what context do you need a new drive?
Is this for a new PC? Or is this an addition to an existing PC?

How much do you wish to spend on this?
 


A "new desktop".
Based on your initial question, many other questions present themselves.

What other parts are you buying?
What is the total budget?
What will this be used for?

But to your question, a WD Blue 7200RPM or WD Black.
