MBP HD Upgrade Comparison

[Whits]

I'm thinking of upgrading my MBP's hard drive and had a questions about what to purchase. These are the ones that I am looking at:

http://eshop.macsales.com/item/Seagate/ST9320421AS/

http://eshop.macsales.com/item/Western Digital/WD3200BEKT/

I'm wondering if there's any major differences between those 3 that would make one better than the other. I know the rpm speed is the same on all of them, but that's as far as my spec knowledge goes when it comes to hard drives.

Thanks!

From what it looks like to me the Seagate's specs look marginally better in a few categories (power consumption, latency). Are there any major differences?
