New Hard Drive in MBP 13" 2010 model

[smats]

quick question and sorry if its been asked before (probably has)
Im thinking of upgrading my MBP hard drive up to around 500GB or 1TB (5400rpm and 8 cache). I know Mac's are funny when upgrading things so is there a limit to hard drive space?
Also how much power does the current hard drive use as i dont want to loose much battery life.
will it slow down my mac at all, i have heard about people getting problems when upgrading hard drive.
Lastly will it void any of my warranty (i know the new hard drive wont be under warranty)

thanks 🙂

Inexpensive, large, noticeably faster (see youtube video). Slight increase in noise/vibration. Battery time about the same.
