Hey. I'm about to buy a MacBook Pro 15-inch, but I can't decide wether to go with a 750 GB Serial ATA-HDD or a 128 GB SSD. The MacBook will be used mainly for video editing in After Effects as well as some games, so I feel like 128 GB is way too small, and I can't afford the 256 GB SSD either. But I really wan't the computer to be fast and easy to work with, so an SSD would be ideal but I just can't afford a bigger one. Are there any options to this or should I just go with the 750 Serial ATA-HDD? Also, how exactly does the Time Capsule work and could this be an option to go with? Thanks for any input.
