Hi all Just after some advice. I want to virtualize Windows and Linux on my MBP 13" 2011. To make this quicker I plan on upgrading to 16GB RAM, and replacing the stock HDD with either (1) a single 512GB SSD, or (2) 2x256GB SSD via Optibay. If I used the two SSDs I would have one dedicated to storage for the virtual machines, and one dedicated to OS X. Which option is better? Thanks.
