could someone compare these 2 hard drives for me? I'm not that smart with hard drives, and I'd like to know teh difference, and which would better to buy. the first is 40GB and the 2nd is 80GB and their the same price.

They're both fine, but for the same price, logic would tell you to get the bigger one.

Isn't serial harddrive suppose to be faster than the IDEs?

Yes, SATA > PATA.

Dewd, #2 is way better. 8meg cache rather than 2meg, 2x drive space, faster interface, better warranty even.

Just check to make sure you can have a SATA drive.

How would you find out if you can or cant have a SATA drive?

You will have SATA controllers on your motherboard. Go to the motherboard mfg's page and see what the board offers.

Serial ATA connectors look like this:

If you have some of these on your motherboard, then get the one on the right. Otherwise, try to find the same drive (the 8M cache is the kicker here...) with a PATA interface.
