Need to replace inter HDD, what to get?

I have a 24" Aluminum iMac (post september '07) and recently my internal HD failed. yay.

now, I need to replace it but I dont know what HD to get.

My current drive is 500GB, has a 32mb cache and transfer rate of 3GB/s

I was looking at a 1TB Caviar Black WD hard drive with 64mb cache and 6GB/s @ 7200 rpm

Will ANY 3.5" drive work??

THANKS

Not any 3.5" drive, it has to be SATA. The one you mentioned will be fine.

Thank you.

Your reply is greatly appreciated !
