Ok so is what I want to do "add as storage" Like I just insert it to my pc and my 160gb drive would be drive c and my new 500gb would be like drive d? Then it would be kind of like a usb drive? Like I can drag any files I want into the 500gb?
Yes. That us just how it works.
This is an idea of what you can do with multiple drives or even multiple partitions on one drive.
In this case c: is windows d: is files f: is some games: h: is windows 8. The missing letters are optical drives.
I am not calling your 160 slow because it is old or new. It is slow because platters now hold more data per square inch. So the 500 should be faster.
Just to give you an idea of how far drives have come.
Think back to 60gig drives. then 120,
At the time, that 120 was fast and 2 in raid0 was even faster.
Fast forward....
Next thing you know. 2TB drives with even more speed.
