Hello! First off, I'll be ordering from Newegg Canada: https://www.newegg.ca 1. I want an external hard drive that holds at least 4TB. It'll be for backing up music and movies. I would like it to not only be compatible with my MacBook Pro, but Windows PCs as well, in case I get one down the road! 2. I'm looking for a Blu-ray drive I can plug into my MacBook Pro. Right now I have an external DVD drive from Apple, and it's fine, but it doesn't support Blu-ray. Any advice? Thanks!
