Upgrade time

Nope, pretty sure that's a PATA drive, I looked it up on Seagate's website and it says "Interface - UltraATA/100."

You need a drive with the following specs:

2.5" diameter
9.5mm thickness
SATA interface.

 

it only takes 2-6 minutes to replace. what you link with drive isn't compatible. you need SATA (Serial-ATA 150) drive.

 

Exactly.

If you're looking for a speedy 160GB drive, then there is only one model to look at- The Hitachi Travelstar 5K160.

 

Why not the Seagates?

I don't know, I have this pathological fear of anything HGST nowadays.

Those are your options with Seagate ATM. I'm a Seagate user myself, won't use anything but.

I'd wait for the 5400.3 models to come out in SATA though, that's when you'll get the higher capacity drives (160GB+).
