What hard drive can I upgrade to?

Hi, I've recently got back out my old macbook pro from mid 2009, unibody 2.53 ghz, and the hard drive is dead on it. I've tried everything to fix it and it's dead. I'm wanting to get a new hard drive, I know mine is a sata 2.5" 5400 rpm, are there any specs I need to know what to look for before I buy a new one?

Also, I've seen some online that has the contacts in the area where it'd be hooked up to a power supply, if I get one with those contacts there, is that okay? I know that the cord in the computer doesn't hook up to that spot, but I'm unsure if I need a hard drive that doesn't have those contacts.

I'm basically wondering if any sata 2.5" 5400 rpm will work or if my macbook takes a specific one?

Thanks for any replies
