My reason for upgrading my hard drive is because id like to run windows 7 via bootcamp. I want to give a decent amount of space for both operating systems. I was on the phone with apple and asked about a 1TB and they said it would slow my computer down ( Late 2010 17" i7 2.8ghz macbook pro). The guy i talked to also said that i may get an excess amount of heat from the bigger hard drive.... Is that true? Id like opinions on what i should do, and if possible id like to get a 7200rpm hard drive but thats a secondary need. Thanks!
