Which HDD to buy ?

[troll_mode]

i am totally new in this area
my computer had old seagates 500gb sata II which i am currently using on my new system
so i went for an upgrade and got a ocz vertex 4 128 gb ssd
i will install os and apps in it but i also want a new hdd of 2tb size. i was thinking of seagates 2tb 7200.14 sata III model and WD black caviar 2tb SATA III .
i want a drive for storage and not for os as i have ssd already.
which of the two will be good for gaming ?

They are interchangeable unless you want to do benchmarking and look for 2% differences. Buy whichever is cheaper in your local store.

And do backups.
