I have a mid 2012 13" MacBook Pro, with HDD and I was wondering if it is possible to upgrade this model to have an SSD running alongside the HDD? The purpose of this, if Ive done my research correctly, is to have the OS running from the SSD to speed things up and then still have the HDD to store my music/photos/films, etc. Getting ahead of myself Ive already bought an SSD, being a Crucial M500 2.5 inch 120gb. Would this be ok for my needs, above? Ive been searching the net trying to find out whether my laptop could have the SSD run alongside the HDD but Ive not found a definitive answer. If its not possible then I guess Ill return the SSD and live with it how it is. If it is possible and someone is aware of a good step by step guide (for the illiterate!) of not just fitting it but having in ready to use and what I made need to consider thereafter due to having 2 hard drives. Many thanks in advance and a happy new year to you all.
