hdd replacement in 27" iMac

My WD1001FALS hdd failed in my 1010 27 imac and I need to replace it. I was wondering if it was worth the upgrade to install the WD1003FZEX or if I should just go ahead and put in another WD1001FALS?

And, will the WD1003FZEX simply plug and play or will I need to make some changes to get it to work in my machine.
